Looking for a way to save money on gifts — who isn’t? Give the best gift of all – and it won’t cost you a penny. Volunteer to help a green charity of your choice. And you can do it right from your home computer.

“Virtual volunteering” is on the rise. And a wide range of groups need your help. You can pitch in with groups devoted to the environment, human rights, disaster relief, animal protection, and more. As a virtual volunteer, you provide skills these organizations need, such as contacting donors or writing letters or grant proposals or other materials they need to publish or post on the Web.

Good Green Charities

To find great environmental charities, go to The Charity Navigator web site, a great guide to intelligent giving, and they will provide you with a list of the best charities in all kinds of categories. You can even break it down by location, if you’d rather volunteer the old-fashioned way – in person.
