Stuck right at the bottom of the food chain, plankton is actually the building block of life on earth. We owe it everything and, still, plankton just keeps on giving as there are dozens of uses for it.

Stuck right at the bottom of the food chain, plankton is actually the building block of life on earth. Our planetary DNA. 3.5 billion years ago, earth's first living organisms were plankton. We owe it everything and, still, plankton just keeps on giving. There are dozens of practical, medical and scientific uses for it. In one form, as something called Spirulina, it might even put an end to world hunger. And, yet, pollution and climate change threaten plankton today. Rising water temperatures, oil spills and the continuous discharge of chemical pollutants into our waterways all contribute to plankton destruction. Fish and aquatic life that depend on plankton for food are dying out. The effects of plankton devastation reverberate all the way up the food chain. Today, protecting plankton is akin to protecting ourselves.—Lagardère Studios
