The year was 1995. The US Fish and Wildlife Service worked hand in hand with a group of Canadian biologists to capture 14 wolves in Canada. They moved them into Yellowstone National Park, where they had been extinct since 1926. In a few years, wolves were already thriving, but that was the least of the changes they brought along with them.
The effects in the park were deeper, better and more striking than expected. The whole ecosystem was transformed. Even the course of the rivers changed! How could wolves provoke such incredible changes in nature? Watch the clip and marvel. Thank you for coming back, Brother Wolf. Laudato Si!
