Fish can slow down global warming-but not if we keep eating them via @qz #climatechange
Humans are pumping roughly 33 billion tonnes (36 billion tons) of carbon dioxide into the air each year. If all that showed up in the atmosphere, it would accelerate global warming even further. The ocean, however, absorbs around half of that CO2. Phytoplankton (essentially, microscopic plants) that live near the sea’s surface take in a lot of it as they photosynthesize, ultimately flushing the CO2 into the cold, dense depths, where it stays trapped for centuries.
