Advice on docs about environment

Hi everybody, recently I started watching documentaries about the environment such as Before the Flood and An Inconvenient Truth 2 (I liked Leo's one better).

Netflix it's kind of hit or miss though, so I don't know what else to watch. I'm just scrolling lists on IMDb but I don't know how trustworthy the user rates are.

Do you have any advice? (it doesn't have to be on Netflix)
