Eight scientists wave goodbye to the outside world before disappearing
for two years into Biosphere 2, a sealed ecosystem in Arizona. The occupants
– four men and four women – will study how people and other forms of life
cope in the closed environment, which covers 1.27 hectares and contains
200 000 cubic metres of space. They hope to survive by recycling the natural
resources available in the biosphere.
