What are your favorite nature documentaries that DO talk about human beings, but NOT in a way that sounds like humans just suck?

Prompted by a post from @krishnanrohit: "I'm once again registering my annoyance at the fact that EVERY SINGLE NATURE DOCUMENTARY talks about how humans suck. Literally every single one. I am so tired of explaining to my 7yo son that no humans are not destroying everything. That he can be optimistic. It's obscene."
