Haha yeah in no way was I trying to say that, "humans are being good caretakers of the planet" because as an overall statement that would obviously be false. However, it is true that there are countless examples, even today, of people being good caretakers of specific ecosystems, or of social/political systems which can impact some ecosystems.

videos or documentaries…about specific conservation efforts that focus on the actual project and what it accomplishs

Yeah, that kind of stuff. Any you'd recommend?
