What If Humans Had To Survive In A Closed Biosphere?
What if we took everything that sustains life on this planet, and shrunk it down to one small bubble? Earth’s biosphere stretches about 20 km (12 mi). From the deep-sea vents in the ocean into the atmosphere. This is where almost all life exists. If we ever want to live in space, or settle Mars, we will have to recreate this extremely complex system. What would you eat? Would you have garbage? What would be the biggest threat to your health?
