Wow.. this was a very interesting article to read. I did know the story about the wolves (pretty sure it was geologist that told me), but never saw it a part of a broader context.

"It does oversimplify complex ecosystems." - I think this is an important note. Removing a keystone can have impact in so many ways aside from the ecological perspective. But I do think that from an awareness perspective this article is really great.

I also keep wondering.. how does one (sea otter) eat a sea urchin...
