Before water hits your Brita filter, it has a lot of stuff in it—and that’s not a bad thing. We’re constantly worried about eliminating the minerals and bacteria that can make water unsafe to drink, but a lot of those things are vital for our food system, as demonstrated by this TED video from marine biologist Tierney Thys, which uses new videography techniques to show what the millions of microorganisms in just one teaspoon of water look like.
Thys’ video, called “The Secret Life of Plankton,” shows the complexity of our water’s ecosystem, and hints at how vital it is or our food system as food for the fish and seafood we serve at the table. But even some of the barely-visible microorganisms are starting to become a direct food source for humans: Krill, one of the zooplankton mentioned in the video, doesn’t just feed fish; it’s also getting harvested in large quantities as an alternative source of omega-3′s to fish oil. Which is why Thys and other scientists are working on videos like this to build environmental awareness and understanding.
Check out the video, and be glad, for once, that there’s so much crap in our water:
