Filmed over 211 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. Directed by Avi Lewis, 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.br br Interwoven with these stories of struggle is Klein’s narration, connecting the carbon in the air with the economic system that put it there.
