Blood:Water Mission

http://www.bloodwatermission.com/
Founded by the Grammy-winning band, Jars of Clay, Blood:Water Mission began because the members of the band were committed to funding a late stage AIDS hospice and through that process realized the link between living with HIV/AIDS and the need for clean water. As a result, Blood:Water Mission launched the 1000 Wells Project in 2005 as a nation-wide effort to raise enough money to provide clean water and sanitation to 1000 communities in sub-Saharan Africa based on the equation that $1 provides one African with clean water for an entire year.

I suppose it all depends on your politics, but personally my faith in corporate owned national media only goes so far. There are tons of documented cases of special interest groups and governments intervening in the media. So how is one to know what's true and what's total BS? That's where SourceWatch comes in. Published by the Center for Media and Democracy, SourceWatch is a "collaborative specialized encyclopedia of the corporate front groups, PR teams, "experts," industry-friendly groups, and think tanks trying to influence public opinion on behalf of corporations or government agencies, highlighting key public policies they are trying to affect and providing ways to get involved." They also give you strategies on researching front groups and uncovering propaganda! Thanks!
