But we are though, we are the biggest threat to the planet and life on the planet, its a good opportunity to have a dialog with your son about some people only think of themselves and others work together for the benefit of everybody

I like the documentaries that show how some renegade humans are trying to save a small percentage of the remaining life from other humans.

Those are my truest heroes .

Please remember individual humans do not suck, but any large group we make is deadly

I mean. Have you stopped to consider why you can't find a nature documentary to fit a "humans aren't destroying the planet" narrative?

Not really what you asked for, but there's a content creator I follow called Animalogic that is generally pretty upbeat and kid friendly I'd say. I can't say they've ever said humans suck, but chances are good that they probably have because that just comes with the territory I think.

Look for your local documentaries about wild animal rehab. Ones on Finnish main broadcast are awesome, but I'm pretty sure they weren't translated except for Swedish.
