Global Green USA released a star studded PSA to get people to stop climate change by demanding that our leaders invest in green technologies and green jobs now. In addition to Serena Williams And Ed Begley Jr. the video includes Mark Ruffalo, Adrian Grenier, Orlando Bloom, Serena Williams, Ed O’Neill, James Cameron, Nia Vardalos, Kyra Sedgwick, Kevin Bacon, Mark McGrath, Walton Goggins and Billy Morrison.

The focus on the campaign is bringing awareness to the the fact that global warming causes our sea levels to rise putting our coastal cities — and billions of people — at risk across the globe.
