Biosphere 2 | 101

On September 26, 1991, four men and four women embarked on an unprecedented mission in the Arizona desert. In one of the most exciting and controversial experiments of the 20th century, they created a mini version of earth under a glass and metal structure and planned to live inside it for 2 years. On this episode of History of the 90s we look at how the privately funded project called Biosphere 2 went from a media darling to what scientists called a colossal failure.
