Google Earth rocks. We've seen it monitor illegal coal mining, keep tabs on reforestation, and inform the masses about environmental issues all over the globe.
But now the US EPA is using it to display nation-wide pollution sources and levels. You can zoom right in on your neighborhood and check out carbon monoxide levels and see the major sources for pollution in the United States.
The one major source of pollution not displayed on this map is transportation. As there are so many cars, and they're always moving around, the EPA can't keep tabs. But everything else is right there at your fingertips. Check out your town and see who your major polluters are.
