You probably heard about it before...Freecycle!
It is the best way to keep things that you no longer want or need out of the landfills. The Freecycle Network is made up of 4,728 groups with 6,632,000 members across the globe. It's a grassroots and entirely nonprofit movement of people who are giving (& getting) stuff for free in their own towns. It's all about reuse and keeping good stuff out of landfills. Each local group is moderated by a local volunteer. Membership is free.
You just visit Freecycle, search for your community ( I just tried it and you have all around the world) and become a member. I have been using Freecycle for more than a year and it is not only the most convenient way of giving things, but you will be surprised about things that are being giving away ( from TVs, to laptops, to DVDs..you name it!)
Join & Have fun....and meet people around your community that share the same passion..taking good care of our mother earth!
Happy Earth Day!
