I’m joining ONE, the global anti-poverty group founded by U2 frontman Bono, for their “It starts with me” campaign, a YouTube video series designed to commemorate World AIDS Day (Dec 1) and inspire global action in the fight against AIDS.

“It starts with me,” which can be viewed on ONE’s YouTube channel, features an initial lineup of video messages and personal stories from a broad range of contributors such as activist Cleve Jones, actors Colin Farrell, Zoe Saldana (Watch!), and Kellan Lutz (Watch!), as well as ONE members and others from around the World, who are committed to the fight against AIDS.

Colin Farrell says of AIDS: “It’s not an African disease; it’s not an American disease.  It’s not a disease that is of any country, any region or any continent … or any sexuality, gay, straight …. It’s just a human disease that has taken so much life, and it continues to do so. It doesn’t have to be that way. As one world, let’s end this.”

In conjunction with the video series, ONE is launching a new accountability report that monitors progress made towards the “the beginning of the end of AIDS.” Specifically, the report analyzes progress made on three key targets–the virtual elimination of mother-to-child transmission, 15 million people on treatment, and the reduction of new adolescent/adult HIV infections–and assesses the political, programmatic, and financial contributions made by a variety of stakeholders.
