Product Description:
#797 Earth Science & Geology - Coastal Dunes (Run time min.) DVD $19.95

At ground level, shallow seas, broad beaches, dunes, and waterlogged hollows seem to comprise a chaotic environment. In fact, there is order and form, produced by the interaction of wind, vegetation, and moving sand. Because sand dunes develop rapidly, the development of a landform can be observed. Measuring wind velocity demonstrates how saltation, sand movement, and erosion happen. The program demonstrates the morphology of dune development and how the complex interaction between it and the vegetation-soil system can be observed and measured. The program also demonstrates how precarious the balance is between the various factors, and how slight changes-including the use of the area by man-can destroy large parts of the system. (20 minutes)

#798 Earth Science & Geology - Waves and Beaches (Run time min.) DVD $19.95

This program examines the various shapes taken by a beach in order to dissipate wave energy. Two beaches are compared-a fairly steep one, a mixture of sand and shingle, and, half a mile away, a flat and sandy one. Field measurement and laboratory demonstration show how wave type and sediment variability cause changes in the beach profile. The effect of wave steepness on beaches can be demonstrated and measured-steep waves producing flat beaches and flat waves producing steep beaches. Simple tools can be used to measure phase difference, wave height, and wave steepness. (20 minutes)

#799 Earth Science & Geology - Valley Glaciers (Run time min.) DVD $19.95

Glaciers are a fundamental component of landscape, with broad historical significance, as important storages of fresh water, and as keys to the study of future glaciation and its effects. This program examines the characteristics of contemporary valley glaciers in the Swiss Alps; the area of snow and ice, with reference to the contribution of ice-fields and cirques; a detailed examination of a cirque glacier; the significance of banding or layering; ice-falls, crevasses, and ogives; the evidence for basal sliding; the character of the ablation zone; the character of the pro-glacial area and particularly the character and behavior of streams. To gain an idea of water loss from the glacier, discharge is calculated by measuring water depth and velocity; the techniques and simple tools for doing this are described. (20 minutes)

#800 Earth Science & Geology - Glacial Deposits (Run time min.) DVD $19.95

Sediment sequences deposited under glacial conditions during the Pleistocene period cover some 10% of the earth's land surface. This program concentrates on the interpretation of a sediment sequence exposed in a river cliff cut by the River Severn in England. Techniques of sampling and analysis are illustrated, with emphasis on the measurement of particle size and of particle dip and orientation. This analysis suggests that the deposits were laid down during a period of glacial retreat. The land forms produced by a more recently-retreating glacier in Switzerland are studied, the vegetation analyzed, and three simple measures are used to distinguish between morainal material, outwash deposits, and lake sediments. (20 minutes)

#801 Earth Science & Geology - Soils: Profiles and Processes (Run time min.) DVD $19.95

This program looks at the way soils can vary even within a small area of a forest. A well-developed podzol is examined in detail, with samples taken from the center of each horizon and then analyzed for organic content, soil acidity, mineral content, and particle size distribution. The measurements and analyses demonstrate why three soil profiles can be so very different in closely contiguous areas, with the same underlying sand, the same climate, and similar if not identical vegetation. The differences are due not to soil types, but to different processes at work. (20 minutes)

#802 Earth Science & Geology - Catchment Studies (Run time min.) DVD $19.95

This program follows the route taken by rainwater through a number of different catchments and evaluates the response of these catchments to a rainfall event-a response represented by the flood hydrograph. The program was photographed in the Santa Clara valley in southern California and in Wales. It emphasizes the tools and techniques necessary for a catchment study and subsequently compares the effect of vegetation on the discharge of two rivers by using the measurement techniques taught in the program. (20 minutes)

#803 Earth Science & Geology - River Channel Forms (Run time min.) DVD $19.95

This program analyzes the dynamic nature of rivers and the relationship between their forms and processes. It examines the various functions a single river needs to perform, and shows how to measure river form and process, relate the two, and synthesize several attributes of the form of a river channel. It examines the differences between low and high flow, and explains how to calculate the quantity and velocity of water transport and how to attempt to measure the amount of bed-load. It compares bankfull and low flow and upstream and downstream discharge, shows how man's intervention has solved a low water problem, and asks students to try to deduce what will occur during a flood. (20 minutes)

#3310 Earth Science & Geology - Flood Control (Run time 20 min.) DVD $19.95

The lowland basis around Los Angeles contains the most extensive water conservation and flood control system in the world. In 1917, work began on a system of dams and improved channels to control the floodwaters entering the basin. This program looks at the way this system was built and the problems entailed in its design and construction. (20 minutes)

#3311 Earth Science & Geology - Slopes (Run time 20 min.) DVD $19.95

This program examines some characteristic lakeside slopes that at first sight seem to present a random assortment of shapes and sizes. It attempts to establish whether any order can be discovered in such apparent chaos and to understand the ways in which these slopes have developed. (20 minutes)

#3312 Earth Science & Geology - Limestone (Run time 20 min.) DVD $19.95

Limestone has a great advantage in that its landforms are produced by only one process: solution. This fact can be exploited to provide information on one of the central problems of physical geography: the rate at which landforms develop. In effect, a limestone landscape provides a kind of outdoor laboratory in which simple experiments can be carried out. (20 minutes)

#34429 Earth Science & Geology - Meteorology: The Science of Weather (Run time 14 min.) DVD $49.95

As landfills continue to close, recycling is becoming a higher priority in urban locations around the world. This program explains how Toronto and Halifax are transitioning from a landfill-oriented strategy to multistage recycling that begins in the home. Footage of a glass/metal/plastic recycling plant, a large-scale composting facility, and a paint reclamation center illustrates how these cities are succeeding in diverting biodegradable and hazardous waste from the garbage stream and recycling them into marketable materials. Related social, political, economic, and other issues are addressed as well. A viewable/printable instructor's guide is available online. (14 minutes)

#5709 Environmental Studies - South America, Wild Kingdom (Run time 26 min.) DVD $79.95

This program shows us South America when it was still an island, separated from the North by water: a peaceable kingdom of unique species found nowhere else, like the armadillo, the anteater, the sloth, and a host of creatures so little endangered by predators that they sported the bright and exotic colors and patterns typical of the South American jungle. Then the Isthmus of Panama appeared; South America ceased to be separate; and across the land-bridge came the much more rapacious animals of the North. The program shows us this land of superlatives and the successive invasions of predators-including the latest and most dangerous, humans. An RTVE production. (26 minutes)

#5710 Environmental Studies - The Sea of Cortez (Run time 27 min.) DVD $79.95

The Sea of Cortez, alongside Baja California, is a biological wonderland that supports vast numbers of sea birds and marine mammals.

An RTVE production. (27 minutes)

#5711 Environmental Studies - The Sonora Desert (Run time 28 min.) DVD $79.95

The Sonora Desert runs from the southwestern United States to northern Mexico-part of the thirst belt in the northern hemisphere. This program probes beneath the appearance of desolation to reveal a world of living things that have adapted to life in the desert. It shows how plants acquire and save the sparse water resources and avail themselves of spectacular colors to attract pollinating birds and insects in the short time in which they can propagate; and it shows how animals withstand the heat of the day, forage for food, and protect themselves from predators for whom they are themselves the food. Cacti, insects, reptiles, birds, and mammals are nowhere more obviously interdependent than in the Sonora Desert. An RTVE production. (28 minutes)

#5712 Environmental Studies - The Tropical Rainforest (Run time 27 min.) DVD $79.95

The rainforest is home to the highest concentrations of life on Earth. This program shows us the South and Central American rainforests-a plethora of different worlds, of sharp and subtle contrasts cloaked in the uniform covering of the forest. Survival is the driving force and we see a vast array of protective devices: spines, camouflage, imitation of more deadly animals, poison; conversely, there are offensive tactics like ferocity and overwhelming superiority in numbers, illustrated most graphically by various species of ants. Of the legendary quetzal, we learn about its elusive natural habitat, its mythical role in Aztec life, and its lamentable role in the conquest of Mexico. An RTVE production. (27 minutes)

#5713 Environmental Studies - Amazonia (Run time 28 min.) DVD $79.95

The Amazon, 4,000 miles long, its basin holding two-thirds of all the fresh water on Earth. Even the superlatives are superlative. This program looks at the river basin, the jungle, and the life within this ecosystem so vital to the survival of life as we know it on our planet: the effects of rainfall and humidity, the balance between predator and prey, the pressure to reproduce, and the struggles, not only between species but between such opposing worlds as those of reptiles and mammals. An RTVE production. (28 minutes)

#5714 Environmental Studies - King of the Jungle (Run time 28 min.) DVD $79.95

Not the lion, who is African, but the puma is the lord of the Amazonian jungle. In the process of showing us the infancy, young adulthood, and maturity of this superbly-adapted animal, this program shows us the other denizens of this colorful and dangerous world in their never-ceasing efforts to survive. An RTVE production. (28 minutes)

#5715 Environmental Studies - The Pampas and the Chaco (Run time 27 min.) DVD $79.95

Pampa in the language of the Incas means "prairie"-a landscape typically devoid of trees and open to the wind, either the dry and cold pampean wind that blows from the south, or the damp and redolently tropical northern zonda. This is the limitless grassland of the gaucho and of a host of idiosyncratic animals and birds like the rhea with unique nesting and hatching behaviors. The chaco, an intermediary ecosystem between the open grassy plateau and the dense tropical jungle, may be a region of trees and bushes struggling in the drought or a landscape covered with lakes and pools. Either way, it offers an extraordinary wealth of fauna. An RTVE production. (27 minutes)

#5716 Environmental Studies - Oceans of America (Run time 28 min.) DVD $79.95

At the southern end of South America, the Atlantic and Pacific Oceans are within reach of each other. In the southern spring, the Valdez Peninsula, the coastal desert of Patagonia's Atlantic shore, is a paradise for sea animals, and in this program we observe Magellanic penguins, right whales and orcas, elephant seals and sea lions. On the Pacific shore, we observe the interrelationship between sea lions, pelagic birds, and the creatures that inhabit the ecologically transitional stage between life on land and under water. An RTVE production. (28 minutes)

#5719 Environmental Studies - The Andes (Run time 27 min.) DVD $79.95

An RTVE production. (27 minutes)

#5720 Environmental Studies - Wetlands of South America (Run time 28 min.) DVD $79.95

This program shows us animal and plant life in a variety of ecosystems all categorized by the term "wetlands." Flood zones, coastal mud flats, and mangrove swamps are all geographically unique but all are rich in birdlife. Here we observe different adaptations for finding and eating food in a watery environment-legs for wading, eyes for sighting, beaks for dabbling or catching food. Other animals, too, have adapted to these environments, from the hermit crab, to the marsh deer, whose specialized hooves enable it to walk in swamps without sinking, to the American flamingos who breed in the Yucatan and have one of the best food-filtering systems in the animal kingdom. An RTVE production. (28 minutes)

#5721 Environmental Studies - The End of the Earth: Antarctica (Run time 26 min.) DVD $79.95

#4120 Earth Science & Geology - The Man Who Moved the Mountains (Run time 50 min.) DVD $89.95

The map of the Earth is a flat picture of the Earth's surface; this BBC Horizon program presents the story of how Harold Wellman changed that picture. Hired by the New Zealand Geological Survey to map the underlying bedrock of the Southern Alps region, he noticed that there were invariably only two kinds of rock, granite and schist. His search for the boundary between the two led to the discovery of the longest straight line on Earth and a radical new theory that describes the Earth's surface and permits geophysicists to explain how mountains are built, and why they are such a prominent feature of the landscape. (50 minutes)

#5539 Earth Science & Geology - Geology: An Introduction (Run time 23 min.) DVD $89.95

Although we have not yet learned to do anything about them, geologists are learning more and more about the gigantic movements that take place within and on our earth. This program shows that continental drift explains earthquakes and volcanic eruptions, presents the methods geologists now use to identify rocks with great precision, and discusses the formation and exploitation of one of our most important sources of energy, oil. (23 minutes)

#5579 Earth Science & Geology - Geomorphology (Run time 23 min.) DVD $89.95

In the five billion years of its existence, the earth has undergone considerable modification. Mountains appear, but no sooner are the ranges and valleys formed than they are flattened by the inexorable forces of erosion. This program describes some of the great forces at work in landscape formation; looks into the modern mapmaking methods that provide ever greater precision in the representation of our planet; and examines teledetection, the satellite-based method that makes possible a better interpretation of the earth's resources and therefore more precise management of resource allocation. (23 minutes)

#5584 Earth Science & Geology - Conquering Mountains (Run time 23 min.) DVD $89.95

Mountains represent challenge, danger, and a window on a different world. This program covers the human ability-and the limits of human ability-to adapt to high altitudes, and the relevant physiological mechanisms; the nature of altitude sickness; the psychological and physical abilities involved in rock climbing; and the nature of avalanches and how their devastation may be reduced. (23 minutes)

#5602 Earth Science & Geology - Mines and Minerals (Run time 23 min.) DVD $89.95

This program tells how minerals are extracted from mines, purified, and shaped, tracing the path from mining exploration to the different uses of metal. We first see how geologists and geophysicists detect certain mineral concentrations from the earth's crust and determine their potential economic worth. We also see how the mineral is extracted from the mine and refined into pure metal through several operations. Finally, we are shown the traditional techniques used to shape precious metals. (23 minutes)

#5635 Earth Science & Geology - Geological Processes (Run time 23 min.) DVD $89.95

This program covers erosion and canyons-how water, wind, and temperature changes sculpt the earth and create deep crevices; why the Grand Canyon serves as a good example of the geological history of our planet; volcanism and petrifaction, which explains why volcanic eruptions can be calm or explosive, depending on the chemical composition of magma and gas; why explosive eruptions create scoria cones like the Sunset Crater in Arizona; how volcanic ashes contribute to the fossilization of plants and animals; and astrogeology, whose computer-synthesized images teach us about the topography and geology of our planet. (23 minutes)

#1378 Environmental Studies - Antarctica (Run time 26 min.) DVD $89.95

Still largely uncharted, Antarctica is already being used as a garbage dump. This program introduces the geography of this continent and contrasts the beauty of the icescape with the discovery made here of the potentially lethal hole in the atmosphere that exposes us to carcinogenic levels of ozone. (26 minutes)

#1385 Environmental Studies - Acid Rain (Run time 20 min.) DVD $89.95

A history and explanation of the history of acid rain and the dangers posed by industrial carbon and sulfur emanations that interact with airborne moisture to produce acid rain. The program provides chemical definitions, illustrates geological and meteorological interactions, and traces the sources of acid precipitation. It also demonstrates ecological concepts, and suggests possible solutions. (20 minutes)

#2131 Environmental Studies - Seas Under Siege (Run time 56 min.) DVD $89.95

Sometimes washing up on beaches in the form of used syringes, other times hidden in the belly of a fish, toxic contamination-the inescapable consequence of toxic wastes flowing or being dumped into the ocean-is a form of pollution found off all coastlines throughout the industrialized world. This program looks at some of the sources of this pollution: industrial effluents, by-products, and waste, stormwater run-off from land treated with herbicides, motor oil slicks left by automotive traffic, and, of course, sewage and toxic waste. It also shows some of the consequences: polluted beaches in New Jersey, 6,000 Baltic seals dead of a viral epidemic engendered by dioxin, English sole in Puget Sound inedible because of liver cancer traceable to motor oil and automobile exhaust fumes. The program is a loud cry of warning, with detailed documentation for proof, that the opportunities for remedial action are growing rapidly slimmer. Says Swedish marine biologist Lars Azelius, "This time it was seals; next time it could be the people living along the coast." (56 minutes)

#2281 Environmental Studies - In the Blood of Man: The Sea of the Imagination (Run time 26 min.) DVD $89.95

Curiosity, intuition, daring, fear, the need for food or to escape, the lure of the unknown-the sea as the visible limit of humankind has inspired creation myths, novels, symbols like Moby Dick and stark realities like Viking warships, attempts to reach out by boat and attempts to shut out those who came by boat. Always-and even in our own technological world-the force of the sea is overpowering, even while we continue to pit ourselves against its power. (26 minutes)

#2283 Environmental Studies - The Blue Highway: Trade Routes Across the Sea (Run time 26 min.) DVD $89.95

The face of the modern world was created by the ships that bound the world together, from Arab dhows, to wooden clippers, to iron steamers, to gigantic container ships. This program traces the history of sea-borne commerce in the Orient: the Portuguese in the 16th century in Macao and Japan, the Dutch and the Dutch East India Company in the 17th century in what is today Indonesia, the rise and fall of Shanghai and Cochin, the consequences of the opening of the Suez Canal, which severed Africa from the trading world to its north. (26 minutes)

#2285 Environmental Studies - The Last Hunters: The Cod War (Run time 26 min.) DVD $89.95

Fishing was humankind's earliest exploitation of natural resources. By the 19th century, fish supplies were rapidly diminishing, and, as the narrator of the program states, "The hunt had become a frenzy." This program examines the problem of overfishing by tracing international controversy over fishing rights from 16th-century Dutch herring fleets, and Grotius' treatise on Freedom of the Seas, to the 1975 war between Britain and Iceland over cod fishing rights off the latter's coast. Rights granted by an international tribunal allowing Iceland to set coastal fishing limits were eventually granted to other nations-a pattern that has reduced overfishing and promoted better commercial fishing management. (26 minutes)

#2294 Environmental Studies - The Frontier of Biomedicine (Run time 27 min.) DVD $89.95

The investigation of simple creatures from the sea has led to new understanding of some of the same life processes in the most complex of living organisms, humans. From studying the proteins related to Alzheimer's disease to extracting chemicals from marine organisms to use as pharmaceuticals, the sea has been a great resource. Sharks are providing fertile clues to understanding the growth, or the inhibition of growth, in certain malignant tumors, while the coral reefs-the greatest battlefields of chemical warfare on Earth-are being explored for means to combat human diseases. (27 minutes)

#2334 Environmental Studies - Life in Arid and Semi-Arid Lands (Run time 28 min.) DVD $89.95

This program explains what a desert is, why it occurs, what kinds of plant and animal life it sustains, and how that life is adapted to-or adapts to-the lack of water. The primary focus is on the effects of growing populations in arid or semi-arid regions: lack of vegetation leads to overgrazing, humus mineralizes, rare rainfall creates runoff and washes away the remaining topsoil, the soil becomes hard and impermeable to water, dries out, and becomes infertile. Thus the desert grows.The desert of Thar in northwest India is a case study of the problem, with a population of over 10 million plus 20 million cattle. How can the people of this region survive? How do they feed themselves and their animals? What do they use for shelter and fuel? This example, and that of the Bichnois-who have created green oases in the desert-are used to show what can be done. (28 minutes)

#2335 Environmental Studies - The Desert as Laboratory (Run time 28 min.) DVD $89.95

This program looks at two deserts that are being used as research models in an effort to understand the role of humans in the desert ecosystem. In the Mapimi in northern Mexico, scientists are studying the best methods of irrigation, the disposition of salt in irrigation water, and the introduction of optimum crops where irrigation is possible and of strictly quantified grazing elsewhere. Important knowledge has also been gained from the Mapimi on the effect of rainwater on barren soil and on soil with vegetation. In the desert between Lake Turkana and Mount Marsabi in northern Kenya, scientists are seeking to control desertification caused by overgrazing and over harvesting wood, by identifying the most productive and ecologically nondestructive foods for animals. They are also trying to identify ecologically beneficial adaptations in lifestyle which the nomadic tribespeople would be likely to accept. (28 minutes)

#2336 Environmental Studies - Life at the Top (Run time 28 min.) DVD $89.95

Nepal, high up in the Himalayas, is one of the most beautiful and poorest nations. This program reveals the variety and nature of life on high and examines how people have managed to sustain themselves in the past, at a cost that can no longer be paid as deforestation and other forms of environmental exploitation have begun to undermine living conditions. At this critical juncture, the population of Nepal has reached the maximum its territory can feed: with crops grown at the greatest possible height in the summer and grazing animals at lower altitudes in the winter, the country is using every square inch of land possible to supply food. The yield cannot be increased and the land area is not enlargeable, while the population continues to increase. What are the possible solutions? (28 minutes)

#2337 Environmental Studies - Equilibrium in a Mountain Habitat (Run time 28 min.) DVD $89.95

As populations increase, as forests are cut down, and habitats and species destroyed, governments are sometimes able to set aside areas as protected areas. This program looks at two such areas, one in India's jungle region, the other in the mountains of central France, where human habitation over millennia denuded the forests to the point of making the area unlivable and which is now becoming a model of how man can live in stable equilibrium with other animal species and with plants in a mountainous environment. (28 minutes)

#2338 Environmental Studies - The Tropical Rain Forest (Run time 28 min.) DVD $89.95

Most forests are in the tropics, on either side of the equator. Temperatures are high and rainfalls are heavy and not seasonal. This program looks at the ecosystem of the rain forest: the height of the trees and the adaptation of leaves to heavy rainfall; the richness and variety of plant and animal life; the role of lianes, epiphytes, bromeliads, and carnivorous plants; the ecological roles of marsupials and monkeys, birds and mammals, herbivores and carnivores; and the unique insect life in the tropical forest. (28 minutes)

#2339 Environmental Studies - Preserving the Rain Forest (Run time 24 min.) DVD $89.95

Humans came out of the African forest, and continue to live in equilibrium with the tropical forest in Africa, Brazil, and elsewhere-hunting, fishing, collecting plants. Trouble only begins when humans begin to cultivate plants in the forest, cutting down trees and burning brush; the soil is soon exhausted, and the would-be farmers move elsewhere. As long as this is done on a small scale, nature can heal the damage, as happened among the Mayas of the Yucatan. But population growth combined with greed and technological efficiency have long since outstripped the ability of the forest to regenerate itself and are boding ecological disaster. In counterpoint to the unimpeded destruction of the Brazilian forest, the forest of Tai, in the Ivory Coast, is an example of a tropical forest habitat that is being used as a natural reserve and as a site for controlled agricultural and industrial activity. (24 minutes)

#2340 Environmental Studies - Coastlines (Run time 28 min.) DVD $89.95

They appear like permanent lines on maps, but coastlines are in constant flux, eaten away by erosion and extended by deposits of sand and stone carried by water. This program looks at the vegetation that is gradually established; at the continental shelves; at the extraordinary and diverse forms of life that flourish at water's edge or in shallow waters, on land and in the water; and at the structure of coral reefs. (28 minutes)

#2341 Environmental Studies - Ecology of the Coral Reef (Run time 28 min.) DVD $89.95

This program looks at the ecosystem of coral reefs. It examines the natural disasters that threaten them, like severe storms, or the proliferation of a species like the starfish, which is ravaging the Australian Barrier Reef-perhaps a natural event, perhaps the result of an artificially-induced change in the environment that is destroying the starfish's normal predator. In seeking the reasons why coral reefs are shrinking everywhere, the program looks at the effects of pollution: particles in suspension in the water that affect photosynthesis in marine plants or that settle and upset the surfaces inhabited by marine life; the result of deforestation and run-offs; the effects of sewage on algae, which compete for space with coral; and the effect of people, from fishermen who overfish to tourists who destroy beaches to oil companies whose tankers spring leaks and destroy everything in the water and on shore. (28 minutes)

#2342 Environmental Studies - Lagoons (Run time 28 min.) DVD $89.95

Lagoons are nature's preserve for fish, waterfowl, alligators and other reptiles, and mangroves and other indigenous vegetation. The nature of the lagoon-its calm waters, which make for good fishing and provide an excellent port-has proved a lure to the species that is destroying the lagoons by building cities on their shore: humans. Venice, Abidjan, and Miami are examples of such cities. This program looks in detail at the Everglades, a huge wetlands area exhibiting all the glory and all the problems of such a space: diversion of water for human purposes; the effects of chemicals on the ecosystem; and the signs of increasing pollution-the proliferation of algae into floating islands of floating vegetation which destroy not only the waterways but also the very advantages that drew humans to the lagoon. (28 minutes)

#2343 Environmental Studies - Wetlands and Pinelands (Run time 28 min.) DVD $89.95

This program is devoted to a study of wetland ecosystems, from the Pine Barrens of New Jersey to areas of Mexico and Belize, where government regulation and environmental planning are recognizing the role of humans in the ecosystem-demonstrating that it is possible to save both humankind and earlier indigenous species. (28 minutes)

#2344 Environmental Studies - Urban Ecology (Run time 24 min.) DVD $89.95

With world population topping 5 billion and industrialization and agricultural mechanization both increasing apace, the greatest stress point is the city. The population of Mexico City was 8 million in 1970; 18 million in 1990; it will exceed 30 million by the year 2000. The problems multiply with the population-housing, employment, food supplies, transportation, and waste disposal, to name only a few. The problems come with urbanization, but they are different in different cities. This program looks at the city of Abidjan, capital of the Ivory Coast-a city created at the end of the 19th century by the French colonial government as the country's administrative center. A railroad terminus was built, the port developed, and streets laid out on a grid. After independence was achieved, the city became more important and more crowded, with population growing 10% annually. The result: denser and denser housing, fewer and fewer amenities, and less and less public effort to control or ameliorate the problems. (24 minutes)

#2345 Environmental Studies - Toward a Livable City (Run time 28 min.) DVD $89.95

This program looks at the development of Barcelona, a city dating to pre-Christian times, which grew slowly until the advent of the Industrial Revolution. After World War II, growth began to accelerate, the inner city became more crowded, the wealthier people moved to the suburbs, and real estate speculation and exploitation were rampant. Then the government moved in and planning began. The goal was to make urban life more pleasant: old, disused buildings were torn down, green spaces opened, advantage taken of the natural landscape of mountains, beaches, and the Mediterranean. These are luxuries that third-world cities cannot afford. Nevertheless, there are minimum standards of livability, and the program shows how the results of research can be applied to improve the allocation of scarce resources in housing, transportation, fuel consumption, air quality control, and waste disposal. (28 minutes)

#2401 Environmental Studies - The Greenhouse Effect (Run time 26 min.) DVD $89.95

A life-sustaining envelope of gas surrounds the earth. This atmosphere contains oxygen, CO2, water vapor, and other gases-it is what generates climate, which affects all living beings. This program analyzes the sun's gradual brightening and the relationship between sunlight and CO2, explains why the atmospheres of Mars and Venus cannot sustain life, theorizes about the disappearance of dinosaurs and a dinosaur-friendly climate, and explains the relationship between climatic change and continental drift. (26 minutes)

#2402 Environmental Studies - Sun, Sunlight, and Weather Patterns (Run time 26 min.) DVD $89.95

Climate is a changing phenomenon, the first signs of alteration appearing in its day-to-day behavior-i.e., the weather. One readily observable recent climatic change is the increase in the number and ferocity of giant weather events like hurricanes. This program explains the origin of tropical storms, tropical rainforests, and polar deserts. It shows the route and the effect of the Gulf Stream and explains its role in the Little Ice Age of the 16th century; theorizes about the events that caused the Sahara to become desert; and examines the link between these events, changes in the sun's activity, and cycles involving dust storms and volcanic eruption. (26 minutes)

#2403 Environmental Studies - Civilization and Climate (Run time 26 min.) DVD $89.95

Changing climate probably played the decisive role in drawing hominids out of the trees, up on their hind legs, and off in search of food whose supply had been dispersed by the replacement of rainforests by grasslands. Migrations were motivated by the search for food; during ice ages, when sea levels dropped, new areas became accessible and populations spread. Links between climatic changes and emerging civilizations have also been postulated; the collapse of civilizations confronted with climatic challenges to which they could not or would not adapt is clearly documented: the Indus River civilization, the Viking settlement in Greenland, even the French Revolution. And Hitler's disastrous decision to invade Russia in 1941 was apparently based on inaccurate weather forecasting! (26 minutes)

#2404 Environmental Studies - Modifying the Weather: The Case of the Man-Made Desert (Run time 26 min.) DVD $89.95

By building roads, watering crops, and grazing cattle, we are constantly changing the climate. We may also modify the weather by cloud seeding, though there is no scientifically accepted proof that rain or snow would not have occurred naturally in cases where seeding appears to have been successful. This program shows how migration in the Sahel has altered regional climate; examines the tomorrow-be-damned policy of water usage in Arizona; and investigates the drastic miscarriage of good intentions in Central Asia, where efforts to irrigate the desert turned into the worst climatic disaster in the history of the Soviet Union: the drying up of the Aral Sea, once the world's fourth-largest lake. The program details how this catastrophe happened and reveals its consequences for the population, the physical geography, and the climate of the area. (26 minutes)

#2405 Environmental Studies - Global Warming (Run time 26 min.) DVD $89.95

The history of Earth has been a history of temperature change; people and animals have historically moved to better climes, richer pastures, and areas of more abundant food. The problem now is that "somewhere else" is already occupied; meanwhile, temperatures appear to be rising, with foreseeably disastrous consequences. The gases in the air which cause the greenhouse effect have made life possible; too many gases, however, and catastrophe looms. Observation, historical records, and computer models lead to the conclusion that temperatures are rising, though no one can be certain how high they will go, or when, or what will happen. Low-lying areas will be under water, of course, as ice melts and sea levels rise; diseases and predators will proliferate; rains will increase in some parts of the world, while drought strikes elsewhere and mass starvation results. (26 minutes)

#2406 Environmental Studies - Danger Ahead: Is There No Way Out? (Run time 26 min.) DVD $89.95

If the threat of global warming has been created by our reckless use of technology, can we use technology to eliminate the threat? We could try to cool the earth by deliberately polluting the atmosphere, as volcanoes do, but suppose we overcooled the planet, creating another ice age? This program suggests some less drastic solutions to the problem of global warming: reducing CO2 emissions; harnessing the energy of the sun and the wind; using nuclear power; conserving energy; curbing or stopping the use of CFCs; and preserving the rainforest. But the basic fact is that greenhouse gases are produced by fundamental biological processes, and there is no reasonable way to stop their proliferation. It may also be taken as a given that, while individuals may be able to adapt to climatic change, societies cannot. (26 minutes)

#4904 Environmental Studies - Prime Minister and Environmentalist: Gro Harlem Brundtland (Run time 30 min.) DVD $89.95

In 1981, Gro Harlem Brundtland became the first woman to be elected Prime Minister of Norway. Her political career has been marked by a zest for social reform and an active role in changing the status of women in Norwegian politics. A Harvard educated physician by profession, Brundtland has also been a prominent environmentalist throughout her political career. In this program with Bill Moyers, she speaks to the sense of environmental urgency facing policymakers today and introduces the concept of "sustainable development." Brundtland also talks about the increasingly important role of women in politics. She says, "If both sexes are not equally involved in building society, in making an impact on society, making political decisions, then you don't have a democracy." (30 minutes)

#4962 Environmental Studies - The Greenhouse Effect and Global Climate: Jessica Tuchman Mathews (Run time 30 min.) DVD $89.95

How serious is the "greenhouse effect" on global climate and the environment? Very, says Dr. Jessica Tuchman Mathews, a Ph.D. in biochemistry and biophysics. We are now facing the specter of the "greenhouse effect," the prospect of overloading the earth's atmosphere with gases released when industrial nations burn fossil fuels like coal and oil, and the Third World strips its forests to farm and burn firewood. In this program with Bill Moyers, she contemplates just how much the earth and the heavens can stand. Mathews suggests that advances in technologies and international cooperation are necessary if the world is to save itself from ecological disaster. (30 minutes)

#4980 Environmental Studies - Assessing Our Planet's Health: Lester Brown (Run time 30 min.) DVD $89.95

There is more air pollution this year than last. There is more water pollution, more toxic waste, and more poisoned wildlife. There are fewer trees this year than last, and that means more desert and less land to grow food to feed a world population that keeps growing. As founder of the Worldwatch Institute, Lester Brown has tackled these environmental problems head-on. Brown and his colleagues have suggested solutions for numerous environmental dilemmas, and have published numerous reports on topics ranging from nuclear power and the potential of the bicycle to deforestation and soil erosion. In this program with Bill Moyers, Brown discusses the possible dire effects of global warming, and stresses the importance of the world's countries working together toward an environmentally sustainable economic system. (30 minutes)

#5040 Environmental Studies - Future Talk (Run time 60 min.) DVD $89.95

Featured in the program are industry representatives and grassroots environmentalists who examine corporate America's willingness to protect the public's health and safety. The program travels to a rural Louisiana area known as "Cancer Alley" where we meet citizens struggling to get the chemical industry to operate in a responsible manner. (60 minutes)

#5062 Environmental Studies - The Politics of Trees (Run time 60 min.) DVD $89.95

This program with Bill Moyers looks at the ongoing debate on how we manage the rapidly disappearing old-growth forests of the Pacific Northwest. Is the timber industry pressuring the forest service to cut trees in violation of environmental laws? Are environmentalists hurting the economy of the Pacific Northwest? What effect has overcutting on private land during the 1980s had on our environment? Featured in the program are environmentalists, politicians, and industry representatives who debate these issues. (60 minutes)

#5107 Environmental Studies - Anaerobic Waste Water Purification (Run time 14 min.) DVD $89.95

Soil, air, and water in the Netherlands are heavily polluted, and stringent efforts are being made to clean them up. An example of this is the development of anaerobic waste water purification. Industrial effluent is purified by bacteria under anoxic conditions. Cees Buisman specializes in the use of sulfur bacteria to remove harmful substances. The processes he uses are very similar to what happens in an ordinary drainage ditch, only much quicker. (14 minutes)

#5108 Environmental Studies - Coastal Erosion (Run time 14 min.) DVD $89.95

The coastal defenses of the Netherlands consist of dikes, sandy beaches, and dunes. Each year it becomes more and more evident how vulnerable the coast is: stretches of beach and dunes simply vanish into the sea, while elsewhere new land is created by sand which is washed up. Geologists are investigating the processes involved in the silting up and washing away of sand. Some factors which play a part in this are the force of currents, tides, the height of waves, wind, and the coastal profile. To gather information about the behavior of sand in water, the Ministry of Public Works has filled in a gully between two sandbanks off the coast of an island, in the hope that waves will carry the sand deposited in the sea up onto the beach, and that it will remain there in the future. (14 minutes)

#5199 Environmental Studies - The American Wilderness (Run time 26 min.) DVD $89.95

Wilderness, this program tells us, is a state of mind, a dream of peace, a return to the primeval world before humans tried to remake nature for their own convenience. But the American wilderness was also something that, when this country was being built, represented danger or existed as something that had to be endured before prospectors or traders could get to the other side, whatever was on the other side. Here we see the world's first designated wilderness area, New Mexico's Gila Wilderness, with its pristine natural wonders and its relics from the past: the now-lost grizzly bear; prehistoric Indian cave dwellers; and memories of the Apaches, Spaniards, and Anglos who sought to escape the wilderness and build civilization. (26 minutes)

#5515 Environmental Studies - The Environment (Run time 23 min.) DVD $89.95

Every day, in every way, humans seem to find new ways to despoil our planet. This program takes a global look at such problems as PCBs and acid rain. In the end, breathtaking imagery enables us to visualize the meaning of the greenhouse effect and depletion of the ozone layer. (23 minutes)

#5525 Environmental Studies - Oceanography (Run time 23 min.) DVD $89.95

The oceans are immense reservoirs filled with natural resources which also constitute a highly complex and fragile environment. This program shows us both realities and explains that the two are not necessarily incompatible. It begins with a voyage into the microscopic world of phytoplankton, source of all ocean life. We also learn about the tides, what causes them, and how they are forecast. Lastly, we look at aquaculture, a technique that enables us to farm the oceans without disrupting their balance. (23 minutes)

#5555 Environmental Studies - Science and the Third World (Run time 23 min.) DVD $89.95

(23 minutes)

#5558 Environmental Studies - Fighting Pollution (Run time 23 min.) DVD $89.95

The war on pollution in all its forms is a pressing priority that brooks no delay. Although much remains to be done, the technology to restore our environment is already in existence. This program describes three examples of such technology: the purification of drinking water; urban and industrial sewage treatment; and vacuum pyrolysis, a revolutionary procedure that makes possible the total recycling of troublesome waste products such as tires. (23 minutes)

#5581 Environmental Studies - Noise, Radioactive, and Electromagnetic Pollution (Run time 23 min.) DVD $89.95

Only a Rip van Winkle could still be unaware of the many problems threatening the balance of nature. This program deals with other, more insidious forms of pollution: noise pollution, which can destroy hearing; radioactivity, which affects us at the cellular level, causing mutations and cancer; and electromagnetic waves emitted by high-tension lines and most electrical appliances, which may also have negative effects on the human body. The program explores the possible effects of these three sources of pollution and the controversies they elicit. (23 minutes)

#5593 Environmental Studies - Ocean Resources (Run time 23 min.) DVD $89.95

This program focuses on some new uses of traditional resources from the oceans: oyster farming, a field where science and tradition are joining to improve the quantity and quality of oysters brought to market; the extraction of chemicals from seaweed, which has found industrial and medicinal applications; and the use of organisms from the sea for a host of purposes, from coral to replace bones to fish oil preventing heart disease. (23 minutes)

#5616 Environmental Studies - Water (Run time 23 min.) DVD $89.95

This program looks at the composition and properties of water and its ability to adopt different forms and move from one to another as it circulates continuously between earth, bodies of water, and the atmosphere. The program also looks at two specific kinds of water: mineral water, which has different uses depending on the minerals it contains; and rain water, which can be a serious source of pollution for waterways that run through cities. (23 minutes)

#5619 Environmental Studies - Waste Disposal (Run time 23 min.) DVD $89.95

Household waste can cause pollution of all kinds, but more and more of these wastes can be recycled effectively and economically. The result is reduced pollution and a useful new source of raw materials and energy. Hospital waste disposal presents the additional problems of contaminated waste, which is a series of problems depending on the nature of the waste: contaminated blood waste, for example, requires different treatment from radioactive waste. Finally, there is animal waste, which is natural enough but nevertheless the cause of pollution if it is not properly treated. The program also shows how pig waste is treated. (23 minutes)

#5623 Environmental Studies - Fragile Ecosystems (Run time 23 min.) DVD $89.95

This program looks at three fragile ecosystems, all in danger of destruction from human activity: marshes, the implication of whose destruction on wildlife, water tables, and an increasing number of other aspects of the entire biosphere is only beginning to be understood; soils, where greater understanding is contributing to more protection; and the atmosphere, which we have already managed to alter to such an extent that the climate of the planet may have been altered. (23 minutes)

#5624 Environmental Studies - Principles of Ecology (Run time 23 min.) DVD $89.95

The principles of ecology establish the relationships that interconnect humans as a biological species with each other and with their environment. This program also considers the Gaia Hypothesis and the view of the planetary ecosystem as a gigantic living organism, and explores the urban ecosystem, which must provide its population with an adequate environment. (23 minutes)

#5630 Environmental Studies - The Florida Everglades (Run time 23 min.) DVD $89.95

(23 minutes)

#5631 Environmental Studies - Ecology of the Southern Seas (Run time 23 min.) DVD $89.95

This program looks at what corals are and how they live; the range of shape and color of mollusk shells, bivalves, and gastropods; and at that most unwelcome of tropical visitors, the hurricane, explaining what hurricanes are, how they form, and how we can track them and forecast their path. (23 minutes)

#5634 Environmental Studies - The Desert (Run time 23 min.) DVD $89.95

This program defines the conditions that create the desert and explains that deserts may be sterile or-like the Sonora Desert-consist of fertile vegetation. It shows the diverse strategies by which different kinds of plants survive the desert climate: some drop their leaves when it is dry and flourish again during the slightest rainfall; others have thick and spongy leaves to retain water. The program also looks at desert fauna: at reptiles such as turtles, lizards, and snakes that are the best adapted for life in the deserts; and at such mammals as the rat, which are also adapted to water-deprived regions. (23 minutes)

#7466 Environmental Studies - The Estrogen Effect: Assault on the Male (Run time 53 min.) DVD $89.95

Will environmental changes brought about by humans eventually destroy the potential for males of all species to reproduce? This Emmy Award-winning documentary explores that frightening possibility. Using sophisticated investigative techniques, scientists trace the ripple effect of estrogenic compounds in the environment. At first, we observe slight changes in the natural order, then witness the wider effects: seriously altered ecosytems and the disruption of fundamental life processes that result in reduced male reproduction. The dismal conclusion is that the process, unabated, may result in male sterility over time. A BBC Production. (53 minutes)

#10913 Environmental Studies - Green Pacts and Greenbacks (Run time 29 min.) DVD $89.95

Environmental protection laws have spawned a whole new form of business: firms that specialize in handling ecological regulatory issues for industry. To what extent are environmental standards achieving the goal of purifying America's air, land, and water? And to what extent are those selfsame standards contributing to the growth of a market geared toward simply meeting the legal minimums in order to avoid penalties? In this program, Betsy Taylor, executive director of the Center for a New American Dream, and environmentalists Dr. Calvin DeWitt and Robert F. Kennedy, Jr., explore the business behind doing business the Earth-friendly way. (29 minutes)

#10914 Environmental Studies - Scientific Spin Doctors (Run time 29 min.) DVD $89.95

For centuries, people have counted on science to provide them with objective answers to questions about the world of nature. But on pressing environmental issues such as global warming and ozone depletion, some special interest groups are striving to bend science to their agendas. Spinning data into webs of rhetoric, such groups run the risk of creating more confusion than clarity, fostering a paralysis of public opinion and environmental policy. This program, featuring environmentalist Dr. Calvin DeWitt of the University of Wisconsin, considers the consequences of exploiting science to shape public policy. (29 minutes)

#6147 Earth Science & Geology - On the Edge of the World (Run time 60 min.) DVD $129.95

We live on the edge of a ball in space, orbiting a star. How do we find out what we are made of and where we came from? It is a daunting task and we can't dig a hole to the center of the earth. We have to look for clues, and they may be unexpected ones. What can we learn from a large earthquake in Bolivia that was felt in Canada, and made the earth wobble for months? What can we see in volcanoes, which bring material from deep underground to the surface? What clues are provided by our neighbors in the solar system? (60 minutes)

#6148 Earth Science & Geology - Plate Tectonics: Secrets of the Deep (Run time 57 min.) DVD $129.95

Viewed from space, one of the remarkable features of our planet is that it has continents and oceans. The changing pattern of the continents and oceans is a very important characteristic of the earth, and the discovery of how this movement occurs is one of the most exciting scientific stories of modern times. The key to this understanding lay not in the continents at all, but in the oceans. The oceans turned out to have a record of their history as precise as tree rings or a magnetic bar code, and with it came the history of relative motion between the continents. These motions are not fast by our standards, but by geological standards they are very rapid. As a description of what is happening in the oceans, plate tectonics is so simple, powerful, and accurate that it has come to dominate our view of the earth's behavior. (57 minutes)

#6149 Earth Science & Geology - Volcanoes: Melting the Earth (Run time 60 min.) DVD $129.95

Volcanoes are among the most dramatic features of the earth, and a sure sign that the planet is alive. But what we see on land is only a small part of the story. In the middle of the oceans about 5 cubic miles of liquid rock is added to the sea floor every year to make new plates. This activity poses a major paradox. We know that the outer part of the earth is solid. How then is it able to produce such quantities of molten rock? With submersible ships we can travel to where plates are created at mid-ocean ridges, where we find a sea floor belching clouds of superheated black water from chimneys. The runny magma that pours from the earth where plates separate can flow huge distances on land and make spectacular displays of fountains and bubbling cauldrons of liquid rock. By contrast, the magma produced where plates converge is often much stickier and hardly flows at all; instead it erupts in catastrophic explosions. Why should these magmas be so different? (60 minutes)

#6150 Earth Science & Geology - The Puzzle of the Continents (Run time 60 min.) DVD $129.95

Curiously, although plate tectonics is very good at describing what happens to the sea floor and the changing distribution of the continents, it is of little help in describing what happens when the continents themselves deform. They behave in a completely different way from the oceanic plates. In the oceans, plate boundaries are very narrow and localized, but on the continents they are spread out and diffuse. When continents collide they crumple up over vast areas-such as from India to Mongolia. When they stretch over wide areas they form basins that fill up with sediment and contain much of the world's oil and gas. Moreover, the continents seem to have a memory, as they break again and again in the same place, even though the deformation episodes may be millions of years apart. Why should the continents be so different from the oceanic plates? (60 minutes)

#6151 Earth Science & Geology - Waterworld (Run time 60 min.) DVD $129.95

Water is an essential ingredient of the earth, and without it we would not be here. Water reshapes our planet's surface through erosion and chemical weathering; the position of the shoreline is one of the most changeable of all geological features. Although it may not feel like it, we are living in an ice age now. At the moment we are in a warm period and the sea level is high. Fluctuations in climate have caused sea level to vary by as much as 400 feet over the last two million years. One of the most astonishing recent discoveries is that the history of global sea level over this period is contained in the composition of tiny organisms preserved as fossils on the sea floor, and furthermore, that the growth and decline of the ice sheets are related to the nature of the earth's orbit around the sun. (60 minutes)

#8487 Earth Science & Geology - The Quake Hunters (Run time 45 min.) DVD $129.95

In January 1700, a massive subduction earthquake devastated a portion of the Oregon-Washington-British Columbia coast. Ten years of research and increased seismic activity have led scientists to believe that another is likely to occur in the same vicinity. This program explores the evidence that remains from that 17th-century quake, including ghost forests, debris from tidal waves, and historic references including Native American legends and the diary of the Shogun. As strain energy continues to build up in the Cascadia Subduction Zone, residents and officials of Portland, Seattle, Victoria, and Vancouver wonder when the next earthquake will occur-and whether they'll be prepared in time. (45 minutes)

#8504 Earth Science & Geology - Dating the Earth (Run time 50 min.) DVD $129.95

The Book of Genesis states that the earth, its heavens, water, and land were formed in six days. But how old is the earth? Up until the 19th century, experts had ascertained the time of the creation at 4004 B.C., less than 6000 years earlier. However, by dating rocks, noting the lack of fossils and bacteria in some areas of the globe, and studying meteorites, geologists have determined that the earth's first landforms emerged 4 billion years ago. This program travels back in time to uncover the place where life began: volcanoes on the floor of the primordial ocean. Original BBC broadcast title: The Time Travelers. (50 minutes)

#8505 Earth Science & Geology - Journey to the Ocean Floor (Run time 50 min.) DVD $129.95

Marine scientists have mapped the ocean floor and discovered that the "spine" of the earth runs down the Atlantic Ocean, then up through the Indian and Pacific Oceans. It is here that the earth's crust was forged, and it is also where living things first existed. Using satellite images and the latest marine technology, this program contains stunning footage of the ocean floor, the underwater volcanic range that is still active, and the myriad creatures that live there. Original BBC broadcast title: The Deep. (50 minutes)

#8506 Earth Science & Geology - Continental Drift: Legacy of Fire (Run time 50 min.) DVD $129.95

Throughout the Pacific Rim there are earthquakes, active volcanoes, and some of the richest mineral deposits in the world. Uncovering the link between these three phenomena reveals the origin of dry land, and solves the puzzle of plate tectonics. This program follows geologists from Bolivia to Alaska as they examine the similarities in rocks found at both poles and use the evidence to prove that the earth's crust has a single source: the volcanoes of the Pacific Rim. Original BBC broadcast title: Ring of Fire. (50 minutes)

#8507 Earth Science & Geology - Death of the Dinosaurs (Run time 50 min.) DVD $129.95

The demise of the dinosaurs remains a mystery. One theory is that a violent series of volcanic eruptions led to periodic mass extinctions of animal life throughout the Cretaceous period. Viewers follow scientists as they trace the evidence deep into the earth's core of molten metal and learn why these deadly eruptions were so vital to the progress of evolution. A BBC Production. (50 minutes)

#8508 Earth Science & Geology - Winds of Change (Run time 50 min.) DVD $129.95

Plate tectonics is the movement of the super-continents as they split apart. They also collided and joined back together again. When they did, mountains, such as the Himalayas and the Tibetan plateau, were formed. These collisions also disrupted prevailing weather patterns and established new ones. See how 7 million years ago, as a result of India colliding with the Asian land mass, Africa became drier, and our ancestors were driven out of the forests onto the savannah. In Asia, this collision resulted in monsoon rains that became linked to the tides in the western Pacific. This comprehensive explanation details how any oscillation in this pattern can result in typhoons and crop failures from California to Kenya. A BBC Production. (50 minutes)

#8509 Earth Science & Geology - Noah's Children (Run time 50 min.) DVD $129.95

Did the great flood, as described in the Book of Genesis, really happen? In this program, scientists travel to Switzerland, Barbados, Greenland, and South Africa to decipher the clues left by history. These include erratic boulders and terminal moraines, coral terracing, microscopic fossils in core samples from the ocean floor, and tiny pockets of carbon dioxide in glacial ice samples. Evidence shows that periods of warming during the earth's previous ice ages caused average temperatures to climb as much as 21 degrees Fahrenheit in a single lifetime, which may have led to global flooding. Follow scientists as they examine the evidence and discuss the possibility of another "Noah's flood." A BBC Production. (50 minutes)

#8510 Earth Science & Geology - Oxygen: The Poison Gas (Run time 50 min.) DVD $129.95

Three billion years ago, bacteria polluted the atmosphere with a new gas, oxygen, and changed the planet forever. This new "poison" gas became the catalyst for life to emerge. But today, humankind is also creating new gases, along with altering the composition of the atmosphere by building dams and removing forests. This program examines the possible consequences of our actions. Original BBC broadcast title: The Living Earth. (50 minutes)

#8511 Earth Science & Geology - The Earth and the Moon (Run time 50 min.) DVD $129.95

Although scientists have found evidence of volcanoes, tectonics, and rivers on Mars, only the Earth, which also has these features, currently sustains life. Why? Scientists have postulated that the answer somehow lies in the Earth's relationship to the Moon. Astronomers are now scanning the galaxy for other habitable planets with the same configuration as the Earth and the Moon. Original BBC broadcast title: A World Apart. (50 minutes)

#7856 Environmental Studies - God's Earth: A Call for Environmental Stewardship (Run time 57 min.) DVD $129.95

This program, narrated by Catholic priest, ecologist, and author, Paul Collins, presents a well-rounded, intellectual discussion of the Judeo-Christian elevation of humankind at the expense of nature and the environment. Beginning with Plato and his emphasis on the spiritual, theologians and ecologists trace the philosophy as it veers toward increasingly anthropocentric ideas. The Bible's mandates for humans to "Be fruitful, and multiply, and replenish the earth, and subdue it..." are discussed within the context of overpopulation and pollution. The entire discussion is presented as a philosophical, ethical, and practical challenge to modern western religions to accept their role as stewards of the environment. (57 minutes)

This series offers a thorough introduction to and analysis of the relationship between climate and humanity: our linked prehistory, history, and likely future. Climate is the determining factor in where and whether life exists-why there is life on Earth and not on Mars and Venus; in specialized organisms where it is hot or cold, wet or dry, light or dark. Climatic change killed off the dinosaurs and brought prehistoric humans out of the trees and upright on their feet to search for food. And climatic change is threatening now to wipe out life on Earth-by drowning, boiling, suffocating, starving, or genetic destruction. These programs examine the nature of climate, what people have done to alter it, whether we are prepared to foot the costs of saving our planet, or to try to reverse the processes we have set in motion by attempting with scientific means to counter the deadly prospects which confront us.

Far from living on a dead lump of rock in space, we are living on jelly, but didn't realize it! These programs trace the story of how and why our views changed-from a fumbling suspicion that continents had moved around, through a detailed reconstruction of how the pieces fit together, to the present, where we can measure the motions directly and see them going on.
