Biosphere Project

Within the biosphere, four women and four men from three countries lived in the Human Habitat during a two year experiment. During this time, they ran the farm and grew their own food in the company of some pigs, goats, and many chickens. They shared the other biomes with over 3,800 species of animals and plants, which are native to those habitats. It was the responsibility of the humans, scientists, and environmentalists to make sure the model of the planet in miniature survived and thrived. In 1991, the doors to Biosphere 2 were sealed for the two-year-long initial program of survival and experimentation.
