This effected all their calculations and the plants did not have enough CO2 to convert into O2. His research indicated that our bodies became highly efficient at utilizing nutrients in everything we ate. Microbes in our organically enriched soils had produced carbon dioxide at a greater rate than our young plants could produce oxygen via photosynthesis. Hundreds of people in different parts of the world live in strange boxes in the middle of wastelands and walk on the sands in spacesuits, trying to feel the delights of life outside Mother Earth.

Allen and his team were swiftly ejected and a new CEO was literally helicoptered in: Steve Bannon. Inside the 2.75acre complex, enclosed in steel and glass like the dome from The Simpsons Movie, 3,800 species of plants and animals were shut in with eight humans (four women and four men) who would be relying on the food grown and oxygen circulated to survive.
