This petition is calling for more limits on pollution and enforcement the US.
In Utah(UT) in the valley of the mountains the pollution is horrible. I have passed many factories and I see tons of smog coming out of the buildings. I have heard that other states have these problems too. Here in UT, some days the pollution is so bad you have to wear a mask and it causes lots of fog. Cars have to get emissions tests, but it doesn't seem like there are any limits on the companies.
This will help people with asthma and other respiratory issues.
Air pollution from smoke and various chemicals kills 3 million people a year: http://www.sciencedaily.com/releases/2007/08/070813162438.htm
People should have the right to breath clean air no matter where they live.
