The Biosphere 2 is truly an amazing display of engineering. The tour takes you through the biomes and behind the scenes of how the biosphere worked when it was sealed. I highly recommend taking a tour which lasts about 1 and 15 minutes. There is...More

Walking though the Biosphere 2 you get a sense for what life would be like on another planet. It is fascinating how each of the elements of our planet, Biosphere 1 :), have been brought together into one facility and co-exist. Would love to live...More

Did realize it was so long ago they locked those 8 people up in here for 2 years. Thing that jumped out at me the most was the enormous size. Cool to think life can be sustained sealed off from the world.
