“When we try to pick out anything by itself, we find it hitched to everything else in the Universe.”

This short video by Sustainable Man shows the incredible impact of an apex predator on its environment, as well as the true interconnectedness of Mother Nature. The narration is from British environmental journalist George Monbiot’s TED Talk, “For More Wonder, Rewild The World.”
