Hayden Panettiere had already made a commitment to saving the whales, and now the Heroes star – and animal activist – is asking for your help. In a new video, Hayden Panettiere urges viewers to sign up on SocialVibe.com and select Whaleman Foundation as a charity of choice. The actress also hopes to get one million signatures for her petition to stop commercial whaling and to enforce the global whaling moratorium.

Hayden Panettiere is not just speaking out – she's also acting out. On Oct. 26, she held an event on Capitol Hill in Washington, D.C. for the Save the Whales Again campaign. "Protecting and preserving whales and dolphins is something that we're all very passionate about," she told a small crowd of people at the rally.

The gathering ended with everyone lying down on the grass to form the outline of a giant human whale and the word, "VOTE" for an aerial photo.

Last October, an arrest warrant was issued after Hayden Panettiere protested on a surfboard in Taiji, Japan. The actress was attempting to protect pilot whales caught by fishermen. – Susan Mandel and Brian Orloff
