Filmed over 211 shoot days in nine countries and five continents over four years, THIS CHANGES EVERYTHING is an epic attempt to re-imagine the vast challenge of climate change. Inspired by Naomi Klein’s international non-fiction bestseller This Changes Everything, the film presents seven powerful portraits of communities on the front lines, from Montana’s Powder River Basin to the Alberta Tar Sands, from the coast of South India to Beijing and beyond. Will this film change everything? Absolutely not. But you could, by answering its call to action.
