Ever since she was a kid, Karen Tam Wu has been an environmental advocate. At the age of 12, after learning about the huge amounts of water and land needed to raise livestock, Karen became vegetarian—and still is. Armed with a degree in forest conservation, Karen has spent many years working to promote and protect healthy ecosystems and the communities that depend on these ecosystems. Nowadays, Karen helps decision makers understand what kinds of programs, laws and technologies leaders around the world are using to reduce carbon pollution and create clean renewable energy. She shares these lessons with community, government and business leaders to encourage them to do the same. Karen lives in Vancouver, where she can smell cedars and the ocean, play in the mountains and ride her bike year-round.
