Love the land: Earth day 2012 Ohlone Park at Sacramento, Berk, 11am, free, What better way to spend Earth Day than picnicking with your family and friends in the park, listening to live music and learning and sharing skills for free?

World naked bike ride Jane Werner Plaza, Castro and Market, SF, 10am, free, . What better way to spend Earth Day than feeling the wind on your skin as you bike naked? Or, as the organizers suggest, topless, bathing suits, body paint—particularly black body paint, as this Earth Day ride commemorates the BP oil spill of April 20, 2010. As such, this is only the second annual Earth Day ride but don’t worry- even if events like these end oil spills forever, there will still be world naked bike rides.
