Toasting Earth Day in an Earth Day Mug?

Searching for "Earth Day Merchandise" brought up thousands of commercial hits on Google: t-shirts, hats, mugs, etc. Some of this is arguably for the better - if you replace your throwaway cup with a mug you bring to your favorite coffee shop each and every time, you will undoubtably be helping the planet. Americans throw away a staggering 25,000,000,000 Styrofoam cups every ear. Even 500 years from now, a foam coffee cup used this morning will be sitting in a landfill somewhere. And Earth Day cloth bags, if used regularly, will keep tons of plastic or paper bags out of our resource use and waste stream. But a lot of the Earth Day merchandise is simply more stuff we don't need (and don't need to manufacture, ship, advertise, etc.), and it promotes the idea that for any occasion we should be buying stuff. The folks at the Huffington Post have a great article about Earth Day Marketing to kids. Check it out!
