I just watched an interesting film called "The Salt of the Earth". It's about a photographer, who leaves his forest home in Brazil, travels the world making photography that captures huge movements on planet Earth. When he comes back home, his childhood home has been destroyed and turned into a desert. Then he tries to turn the place back into a forest. It's inspiring.
The place is now a national park in Brazil, called "Instituto Terra".
