Progressive Environmentalism?

This morning's news alerted me to the fact that California has filed suit against the automobile industry in an attempt to force them to pay homage to their new global warming law. This got me thinking. I know this isn't the first time a major industry has been targeted for good reason. The anti-cigarette ad campaign and the lawsuit that went along with it comes to mind. I like breathing clean air and also love the natural beauty of our country. I also loath having to buy eye drops when I visit someplace else and find that pollution is higher than I am used to. So I really don't have a problem with the California movement towards a better environment. In fact, I applaud them. I would love to applaud other states for being as forward thinking. Since I am not as up on this subject as I would like to be I hope you will enlighten me. Are there other states that are doing similar things? If so, who and what?

On a totally unrelated note: Last night I watched Criminal Minds and when the show was in the last scene they played The Riddle by Five for Fighting. Click on that link and you can watch a video of them performing the song. I just bought the album Two Lights a few weeks ago. Hearing it on TV was way cool!
