The reintroduction of wolves to the Yellowstone National Park started a process of “trophic cascade” —”an ecological process which starts at the top of the food chain and tumbles all the way down to the bottom.”
“And here’s where it really gets interesting….. The wolves changed the behaviour of the rivers. They began to meander less. There was less erosion. The channels narrowed. More pools formed. More riffle sections….. 3.08
The river came alive again — not by humans cleaning it up, but by rewilding and letting the natural processes do the work. I find that lovely. Of course. It is our fundamental delusion to think that things exist independently, like building blocks. Including ourselves.
