Eating our way to Extinction
The most disturbing part is within the first 20 minutes, it doesn’t get much time, and I think a whole documentary could be made of the deforestation on the rainforest.
It’s not only why it’s being cut down, but how that affects the people who choose to live there.
Poison on Tap is a good documentary too, about additives in community water supplies.
Fat: a documentary / Fat 2 and related documentaries are quite educational.
