Hi Michel/Robin - the most significant thing about some plankton is that 
they are coccoliths ie they form calcium carbonate skeletons which end up as 
chalk etc - permanent removal of CO2. In fact, they are a major negative 
influence on CO2 levels by absorbing volcanic derived CO2 and preventing an 
excess building up, however, like all of the natural stabilising climate 
control mechanisms, they have been stressed and pushed to and beyond the 
limits
