Scary but real and amazing message

I don't want to shield my kids from the important messages. I don't think there is currently a better movie out there about the topic. In particular, the concept that humans ARE the environment is so important for the next generation to start internalizing now. It's ok for 7 and older but you'll need to discuss with your kids afterwards to make sure they got the takeaway.

unsure...

I'm not so sure if I would watch this or let any children I know watch this. Environmental documentaries can be scary for adults much less children.
