This Friday marks 46 years since the first Earth Day in 1970. You may not know it, but if you have donated to your local Goodwill or shopped at a local Goodwill store or online you have helped make our planet a little cleaner and a little greener. How much greener? In 2010 Goodwill (and you!) helped divert more than 2.4 billion pounds from landfills through donations to, and purchases from, Goodwill.
