David Greer explains the importance of plankton, those invisible but essential marine creatures:

“Tiny and virtually invisible as most plankton are, they make up more than 90% of the biomass in the world’s oceans and are collectively the lowest rung on the marine food chain. Everything we eat that comes from the ocean ultimately depends on plankton for its existence. As if that’s not reason enough to pay attention to the future of plankton, it’s worth considering that about half of the oxygen we take in with every breath also owes its existence to plankton.”

Like all other life on earth, plankton are threatened by the effects of climate change – with potentially disastrous consequences.
