Salinity, temperatures, and pH levels are controlled. Algae scrubbers control the nutrient and oxygen levels. The Biosphere 2 ocean is a unique area for ocean research. There are many fish such as file fish, sergeant majors, damsel fish, parrot fish, and huge angelfish but no predators such as sharks. The Biosphere 2 Rain Forest has many of the same characteristics as rain forests on Earth.
Rain forests provide oxygen as well as foods, fibers and medicines.
Researchers selected 300 species of plants to be placed inside the rain forest. Biosphere 2 is unique facility with unlimited potential for global research. We are learning about the interconnectedness of Earth's processes, the role of humanity in environmental research and the role of humanity as stewards of our fragile planet. Scientists and research institutions from around the world have expressed interest in working with Biosphere 2 on expanded environmental research programs. Several programs are already in place.
