The environmental impact of oysters, in one photo
The water in both tanks came from the same source. The one on the right has bivalves. Not only do oysters naturally filter the waters in which they live, they can even protect humans from destructive hurricanes. For more, read about New York’s efforts to bring back oyster populations in the once-toxic Hudson River.
Delicious AND helpful. Who knew?

How Wolves Change Rivers
Check out this brilliant short film from Sustainable Human about the effects of reintroducing wolves to Yellowstone National Park, where they had been absent since the last one was killed in 1926 until their reintroduction in 1995.
While recent research suggests that the real story isn’t quite as neat and tidy as the one presented in the film (trophic cascades and food webs are incredibly complex! Who knew?!), it’s a great reminder of how every thread of an ecosystem plays an important part in weaving nature’s tapestry.
