lol... Yes bro. Try living in these areas. Mass Hunting? The fuck you talking about? Currently not in North America... not sure about Canada though. I believe you're thinking other continents, like Africa, where poaching is seriously threatening animals.
When the wolves were reintroduced to Yellowstone, they quickly got of control and were decimating elk and deer populations.... and especially moose.
Now, these stories didn't hit mainstream much, because it doesn't fit the narrative. My brother lived in Cody during all of this... even when Wyoming quietly allowed the hunting of wolves to cut them back. There's a lot of debate by locals on what the fuck to do with them. And there were a lot of Out of State Environmentalists who were severely pushing back on any action to limit the wolf populations.
I'm with you on one point... If you're not going to eat the meat of these animals, there's no sense in hunting in them. But the other end of the argument is that by allowing some hunting of predators, it prevents starvation and too much killing of the prey herds.
And humans are dumb enough to think they can control the balance of nature between predator and prey. We also seem to take actions too far in either direction and cause all kinds of unintended consequences.
