Biosphere 2: The world’s largest Earth science experiment

Biosphere 2 is the world’s largest controlled environment dedicated to understanding the impacts of climate change. Our researchers at the University of Arizona, together with visiting science experts from all over the world, have created the unique biomes contained in Biosphere 2 to help answer the most complex questions of today and tomorrow about sustainability, conservation, and humanity’s impact on Biosphere 1 – our own Earth.
