These wolves don’t often see people and live in an area where wolves aren’t persecuted. As a result, they are bold. Despite approaching to just a few feet away, we felt zero aggression, just curiosity. We humans have done terrible things to wolves. It’s thought that in 1600, there were two million wolves in North America. Due to 400 years of systematic extermination, there are now just 80,000. There's hope that they're on the comeback, but they still need us to stop persecuting them. These top predators keep herbivore populations in check, allowing countless other species to thrive.
