00:00Plankton are everywhere.
00:06The unmistakable smell of the seaside, that's decaying plankton.
00:12The varying shades of blue and green of the ocean, that's plankton.
00:19But just what is this mesmerisingly beautiful and complex organism?
00:24Explain to me, what are plankton?
00:27Well they are the workhorses of the oceans, and not just oceans but rivers, streams, any
00:33water contains thousands and thousands of different plankton species.
00:37They fix carbon dioxide as carbon and then that becomes the biomass, that's the food
00:42source for further up the food chain.
00:45They produce oxygen for all marine ecosystems, marine organisms, and that's really fundamental
00:50for human food security, you know we rely on so much on fish, aquaculture, and they're
00:56all feeding on the plankton so they have a very important role.
