Great. This documentary film is made to make one woman feel good about herself. Talk about narcissism. I don't know how much the documentary film makers were paid by the main protagonist of this film viz. Kristine Tompkins and her associates. Looks more like a PR film to me than anything else.
So first you create multiple multi-national corporations and make your millions while destroying nature. If someone wants to know how, just check what are the raw materials for making the apparel and gear that Espirit, Patagonia and North Face sell. Then you spend those millions acquiring land from erstwhile colonial land-grabbers and their government who drove the indigenous people of South America from these very lands which they were living on sustainably for generations. Next when you understand the scale of the problem and realize that you won't be able to solve it, you turn around and "donate" that land to the very same government. And then make this movie to feel good about yourself. Excellent.
