Isara is a site/organization based in Thailand that is using any ad revenue it makes to help the poor in that area. They're doing lots of good things and it's easy to help.

Instead of using Google or Yahoo as your homepage, use Isara. It's got a Google search bar and Amazon shopping and it makes a nice homepage. As the site gets more and more hits, businesses will pay to advertize on the site, and more money will be raised to do things like send kids to school, renovate Red Cross buildings, etc. Great!
