Phytoplankton are microscopic plants floating around in marine and aquatic ecosystems that produce 50-80% of the world’s oxygen, provide food for countless other organisms, and are so effective at absorbing carbon dioxide that some have suggested growing phytoplankton as a solution to climate change. But sometimes, too much of a good thing can be a bad thing. Agricultural runoff containing fertilizer and animal waste can create massive blooms of phytoplankton, which can have devastating effects on ecosystems, harm human health, and put a strain on the economy. Today, we explore the good and bad of phytoplankton, how climate change plays into this conversation, and where we go from here. With special guest Dr. Ajit Subramaniam: Lamont Research Professor of Biology and Paleo Environment at Columbia University.
