Porpoises fled the toxic waters of San Francisco Bay over half a century ago. A whole generation of Bay Area residents have grown up since, never knowing that porpoises once lived, played, and thrived right in their backyard.

Now, after a sixty year absence, they're coming back! Their return is a sign that things are getting better and that we're on our way to a cleaner and healthier Bay.

These porpoises bring the Bay to life—they are playful and incredibly smart—and they deserve a home right here in the Bay. The only way to keep the porpoises here is to keep pollution out—and that means getting the San Francisco Regional Water Board to stand up to the worst polluters.

Help us reach our goal of 15,000 locals standing up for the porpoises by June 30th, 2013. Add your name right now!
