It is amazing to see the widespread effect that cascades
have on the environment. The domino-like cascade tumbles all the way down the
trophic levels, and beyond…Indeed, as well as disturbing the ecology of and
ecosystem, trophic cascades can end in the complete transformation of the
landscape.
In this excellent mini-documentary, George Monbiot explains
what happened when the wolves were reintroduced in 1995 to the Yellowstone
National Park, and how their reintroduction changed rivers…

Really like this blog. Your examples are very illustrating, and your videos are amazing. You explain everything in a way that makes the concept of cascades easy to understand. The example with the wolves are great, and it is something that has been on my mind for a while because the government in Norway where I come from have decided that wolves are not importent, and that we should not support or take care of our population, which really scares me due to the same reasons brought up here. Good work!
ReplyDeleteWhat an amazing video! That one species can have such a phenomenal influence on an area is quite astounding.
