50 Ways to Help the Planet
Wire and Twine clothing presents 50 ways to help the planet, 
They designed a shirt with little icons to remind you of the fifty ways to help. My personal favorite tip is # 33:
“TELECOMMUTE :: See if you can work out an arrangement with your employer that you work from home for some portion of the week. Not only will you save money and gasoline, and you get to work in your pajamas!”

And a portion of the tee shirt proceeds will go to the Children and Nature Network: http://www.childrenandnature.org/
“The Children & Nature Network (C&NN) was created to encourage and support the people and organizations working to reconnect children with nature.”
