The One Cam­paign fights the emer­gency of global AIDS, star­va­tion and extreme poverty. Mainly a site for Amer­ic­ans, it doesn’t hurt if you add your name to the One declar­a­tion, if you’re from out­side the States. Check out all their part­ners as well. You only need to give a little to make the world a bet­ter place!
