Halle Berry, Pierce Brosnan, Cindy Crawford and Daryl Hannah were among the stars who turned out to protest a planned natural gas facility in Malibu on Sunday.
"We have to use our voices and band together and stop this," Berry said at the gathering. "I care about the air we breathe, I care about the marine life and the ecosystem of the ocean, and I care about stopping this (facility) because if this one is allowed to pass through, there will be other ones that will pop up all around the country."
Brosnan, who lives on the beach in Malibu and hosted the rally, told PEOPLE that he opposes not only the facility, which is proposed for a site 14 miles off the Malibu coast, but the four others planned for California.
"It is my home. It has been for some 23 years now and it's very near and dear to me," he told PEOPLE. 'We're trying to outreach to Governor Schwarzenegger to say before you put pen to paper, before the ink is dry, please consider your action here." (Gov. Arnold Schwarzenegger can veto the proposal.)
Australian energy company BHP Billiton says the facilities would provide a reliable source of low-polluting energy. But opponents say the terminals would not meet clean air requirements and could serve as terrorist targets.
"That (natural gas plant) has the potential to be a bomb that's ready to go off – and not just because of a terrorist threat but, storms, earthquakes, all kinds of things," said Hannah.
Mark Massara, director of the Sierra Club's California Coastal Program, told the Associated Press that the recent celebrity interest "is the greatest thing that has happened to our effort. We have struggled over the last three years."
In addition to the protest on land, out in the water dozens of surfers, including Hannah on her pink board, paddled out to a sign with a message for Gov. Schwarzenegger: The sign featured a picture of the proposed terminal with a red slash through it and the directive: "Terminate it!"
