Marine plankton, carbon heroes!
|Coccolithophores (pictured) among the phytoplankton, plus foraminifera (the most common plankton) and pteropods (tiny marine snails) among the zooplankton have one thing in common: they all use CO2 to make the calcium carbonate they need for their|
|skeletons. So they are vital 'carbon heroes' because, in their trillions, they are constantly removing carbon from the sea and, indirectly, the air. And the phytoplankton put oxygen back into the air; more than all the world's rainforests.|
