>>2589977alright OP I'm making my best suggestion and I want you to hear me out.
This is what my high school sciense teacher would refer to as "an oldie but a goodie".
Fucking beautiful and some of the rarest and most unique nature footage ever taken. I'll give you a quick overview without spoilers: In a National Park in Africa there's a bad drought, the river is drying up slowly. Lots of animals live in the river of course, and even more depend on it for food and water. The river dwindles until nothing's left but some muddy pools. Unfortunately the river is infested with crocodiles and they are PACKED into these shrinking pools. Every animal across the landscape is dying from the drought, including the crocs, and the only way these animals can possibly survive is to drink from the croc pool. The landscape becomes covered in bones and carcasses and the desperate have no choice but to brave a drink of water from hell itself.
It gets FUCKING INTENSE. If you want to know what the apocalypse looks like, this is it.
