Ahoy,
One of the great things about blogs is that we talk (and talk) about things but we often fall short in taking any action. Here is an idea that would allow us to make a difference.
Add the Hunger Site, Rainforest Site and Build a School Site to your blog and everytime you check out your blogroll, click on each of them and those sites sponsers will help feed a child and build schools for those who have no access to education and save 11.4 square feet of rainforest.
It won't save the world overnight but it will buy some food for a child, help the enviroment and maybe give some kids a tool (literacy) that they wouldn't have had before.
