Adam Werbach founded the Sierra Student Coalition in high school and went on to become the President of the Sierra Club at age 23. While there, he helped pass the California Desert Protection Act, which created Joshua Tree National Park and Death Valley National Park, the largest national park in the lower 48 states. He left the Sierra Club to start Act Now, and, controversially, helped Walmart launch its sustainability initiative in 2005. He sold Act Now to Saatchi & Saatchi, becoming Saatchi’s first Chief Sustainability Officer.
He recently founded yerdle, a social marketplace dedicated to reducing the number of new things we need to buy by 25%. Werbach also serves as the sustainability correspondent for TheAtlantic.com. He lives in San Francisco and Bolinas.
