I stumbled across a great eco-networking site - www.carbonrally.com which has great earth-friendly challenges for everyone looking to live greener.
The site puts up new a easy to handle challenge every few weeks and keeps track of how much carbon you save. The current challenge is Cold Then Fold - use only cold water to wash and rinse all of your laundry this month. Previous challenges include biking one day a week, line drying laundry, recycling your old cell phone, and reducing the amount of meat you eat.
If you've got a competitive streak, Carbon Rally has challenges that you can do as a team. So compete as a group, family, or workplace and the planet will win.
