Rainforests store a big fraction of all the carbon on Earth, and soil microbes play a key role in pulling that carbon out of the atmosphere. This episode, researchers take a look at what happens to that storage when a rainforest hits a drought. Tag along with their experiments in a fully enclosed, human-made ecosystem: Biosphere 2.
