From CNN:
The United States is the world's largest emitter of carbon dioxide. The Bush administration wants [emissions] cuts to be voluntary and resists mandatory measures it says would hurt economic growth.
You know what will REALLY hurt economic growth? Not having a planet on which to live.
The VERY GOOD news from the CNN article is that nine states have broken with the anti-science White House and have agreed to cap and then reduce greenhouse gas emissions from power plants. If you live in New York, New Jersey, Connecticut, Delaware, Maine, Massachusetts, New Hampshire, Rhode Island or Vermont: feel proud! Your government cares about the future of the planet!
If you live in California, Washington or Oregon, all states considering similar measures, petition your legislatures and governors directly.
No matter where you live, go the National Resources Defense Council site to do more about a problem that truly affects all of us.
