The band has posted a video on their Twitter, narrated by actress Robin Wright, detailing the campaign's goal to stop the slaughter of 30,000 elephants a year, which are killed for the ivory in their tusks. Pearl Jam's single "Corduroy" provides the soundtrack for the clip.

"Take a stand with [the Wildlife Conservation Network] against the unjust slaughter of elephants," Pearl Jam writes in the video's caption.

Pearl Jam isn't alone among rockers protesting the poaching of elephants -- last year, Slash lent his support to the cause with his video for "Beneath the Savage Sun," which showed graphic footage of slaughtered elephants.
