“The Cove”, winner for Best Feature Documentary at this year’s Oscars, is asking for your help. To prevent the future capture and slaughter of dolphins in Taiji, Japan, the filmmakers joined by celebrities including Jennifer Aniston, Courteney Cox, Robin Williams, Jason Mraz, Woody Harrelson, Mariska Hargitay, Naomi Watts, Ben Stiller, Paul Rudd, James Gandolfini, Hayden Panettiere, and Carrie Ann Inaba appear in a PSA to raise awareness for the Take Part campaign.

The PSA was released in honor of Earth Day on Thursday and asks people to take action in the campaign to save the dolphins on the coast of Japan and shut down the cove for good. The filmmakers’ primary goal is to raise awareness of the dolphin killings to the citizens of Japan, and as a result, inspire them to demand that their government put an end to the slaughter.

You can do your part by signing the Take Part petition either on Facebook or for non-Facebook users at this link.
