Have you ever wondered how much plastic is disposed of in one day? The people at the Plastic Pollution Coalition want us to change the ways we think about, use, consume, and dispose of plastics.

My plan this year for Black Friday was to sit out the retail game altogether. That was before I saw the ad in The New York Times. "Don't Buy This Jacket," exhorted the full-page message sponsored by the Patagonia Common Threads Initiative.

Anyone who grew up in the 1970s in Tennessee can sing a bit of "Tennessee Trash," a comic and catchy PSA that was sponsored by the State Department of Transportation to discourage littering.

Canceling 6,705 individual catalogs stops 40,230 catalogs from being made next year. This will also save 112,644 gallons of water. Impressive results from a simple, kid-friendly project.

Understanding the "life-cycle" of any consumable good offers a fairly accurate sense of how "green" it really is -- basically, where things come from and what happens to them when we are done with them.

Here are six activities that my fourth grade classroom at The Park School in Brookline, MA has been working on leading up to Earth Day.

Some of us recycle them, but more than half end up in the landfills where they decompose, releasing methane, an intense global warming gas. They're a massive misuse of natural resources and energy.

Assuming all gasoline powered cars on American roads had properly inflated tires, drivers could cut gas consumption by 3.3 percent. That's about 13 million gallons of gas every day.

We made the videos as we canceled unwanted sales catalogs for 30 days to save trees, water, energy, and climate. Our school canceled over 3,000 this year saving 40 trees!

For months now, Campania has been suffocating under heaps of uncollected garbage shipped from economically sound northern Italian regions to the much poorer south.

Often, the greenest consumer route is not buying new products made with Earth-friendly methods but rather scoring used products made with traditional, possibly heinous methods. Reduce, reuse, then recycle.
