Climate Change:

Environmental activist Laurie David takes global warming to the mainstream

Activist Laurie David says the environmental movement needs to do a better job selling its ideas to the general public, and is leading the way with a media blitzkrieg. From organizing a televised comedy special about climate change, to promoting the Stop Global Warming Virtual March by giving away a hybrid car owned by her husband -- comedian Larry David -- David is taking environmental policy to mainstream America. But are environmental groups overselling the threat of climate change? And will there be a backlash against the latest celebrity cause? During today's OnPoint, David, producer of the upcoming HBO documentary "Too Hot Not to Handle," discusses these questions and more.
