Annie Leonard spent 20 years working for environmental organizations, studying where our stuff comes from and where it goes. She followed waste from industrialized countries to apartheid-era South Africa, where it was dumped in black townships, to Haiti, where it was disguised as fertilizer and dumped on a beach, to Pakistan, Indonesia and the Philippines where we sent everything from e-waste to used car batteries for recycling in a process too dirty for our own backyard.

Then, in 2007, she made a short animated film about our consumer culture and the damage it does to the environment. The Story of Stuff went viral (chances are you’ve seen it — more than 15 million people have) and spawned a whole series of videos that explain complicated environmental and political concepts in an irresistibly simple and engaging way. The Story of Change is a bit of a departure — instead of looking at the problem, it proposes a solution.
