I found three great sites that allow you to "donate" money just by clicking a button. These sites are funded by various companies who sponsor the site for a day. Every sponsor makes a donation for each user who clicks on the site during the day.
I put these sites in my toolbar and have made a habit of going to them the first time I'm on my computer. It takes less than 30 seconds to do all three.
The sites are:
The Hunger Site
The Animal Rescue Site
The Breast Cancer Site
I just got this link from the blueboards: freerice.com It's a vocabulary test and for every answer you get right, they donate 10 grains of rice through the UN World Food Program to help end hunger.
If anyone knows of other sites like this, please share!
