Though he’s earned critical acclaim for his acting in recent years, Mos Def is more famous for his musical career, and that’s also where his green sympathies shine through. Last fall he headlined the Living Word Festival in Oakland, an event with an “eco-equity” theme that included bamboo-building activities and a green-themed graffiti battle in addition to musical performances, and he tackled water issues in his 1999 tune “New World Water.”
