Sugar’s Role in Climate Change


Phytoplankton living in the surface waters of the oceans are responsible for absorbing up to 40% of all of the carbon that becomes incorporated into living things.

Marine plankton account for up to 40% of carbon absorbed by all living things, but their growth is limited in half of the world’s oceans by iron bioavailability. New research has found that marine plankton can produce sugars that improve iron bioavailability – and hence plankton growth.
