We humans often think we have conquered our world and its various environments and climates. In reality though, we inhabit less than 25% of the Earth's surface finding most of the available territory unsuitable for human life. However, throughout history we have tested the boundaries of human civilization and and have constructed extraordinarily creative ways of protecting our frail bodies. Our clever innovations permit us to brave the bitter cold of the arctic, the scathing heat of our deserts, the depths of our oceans, and even the emptiness of space. Join Dr. Kevin Fong as he studies how our bodies are affected by the extreme environments around us and explains the inventions like the artificial life systems which have allowed us to venture out into the most extreme frontiers.
