With summer now around the corner, we are bracing ourselves for a wave of new naked protests. The last few years showed the power of the naked body in calling attention to environmental issues -- from climate change to animal rights. And with the recent win by New Zealand naturist/activist Nick Lowe to ride his bike au natural in the countryside, we thought we would honor those brave naked souls who decided to bare all for a cause dear to their hearts:

The other featured causes were -- PETA moms protesting again pig farms, Chinese kids strip down for global warming, bloody AnimaNaturalis lie naked in response to fur trade, and hundreds of activists get naked on a glacier to support climate regulation. Read the whole thing on PlanetGreen. What would you strip for?
