Kiva.org allows individuals to make $25 loans to low-income entrepreneurs in the developing world (microfinance). By doing so, individuals like you provide affordable working capital for the poor (money to buy a sewing machine, livestock, etc.), empowering them to earn their way out of poverty.

It's a new, direct and sustainable way to fight global poverty, with a true return on your money.

Anyways, if you have a minute, please check out the site: http://kiva.org. If you need more "reputable" validation than my recommendation :), know that they have received great press in publications ranging from The Wall Street Journal to NPR to BusinessWeek.
