Throughout its career, Pearl Jam has promoted wider social and political issues, from pro-choice sentiments to opposition to George W. Bush's presidency. Vedder acts as the band's spokesman on these issues. The band has promoted an array of causes, including awareness of Crohn's disease, which Mike McCready suffers from, Ticketmaster venue monopolization and the environment and wildlife protection, among others. Guitarist Stone Gossard has been active in environmental pursuits, and has been an advocate of Pearl Jam's carbon neutral policy, offsetting the band's environmental impact. Vedder has advocated for the release of the West Memphis 3 for years and Damien Echols, a member of the three, shares a writing credit for the song "Army Reserve" (from "Pearl Jam").
