Pollution is a serious one. Water pollution, air pollution, and then solid hazardous waste pollution. And then beyond that, we also have the resources issue. Not just water resources but other natural resources, the mining resources being consumed, and the destruction of our ecosystem.

As a black person in America, I am twice as likely as a white person to live in an area where air pollution poses the greatest risk to my health. I am five times more likely to live within walking distance of a power plant or chemical facility - which I do.

Beijing has shown how to tackle air pollution by using smog towers.

If our nation wants to reduce global warming, air pollution and energy instability, we should invest only in the best energy options. Nuclear energy isn't one of them.

Climate change and air pollution know no borders, and antibiotics resistance respects no boundaries. Bacteria from Africa can make people in America sick. The burning of Indonesian forests can keep Asia gasping for breath.

Rhode Island works hard to reduce air pollution in our communities. We passed laws to prohibit cars and buses from idling their engines and to retrofit school buses with diesel pollution controls. But there is only so much a single state can do, particularly against out-of-state pollution.

I strongly support the Bush Administration's clean diesel rules, which will reduce air pollution from diesel engines by more than 90 percent, and reduce the sulfur content of diesel fuel by more than 95 percent.

The environmental effects of the automobile are well known: motor vehicles cause, for example, as much as 75 percent of the noise and 80 percent of the air pollution in our cities, and the industry must face mounting pressure from environmentalists.

I didn't like to stop playing for a second to bother with eating or going to the bathroom. I was a really skinny kid, and I remember my mother always telling people, 'I don't know how she's alive. I think she gets all of her nutrients from air pollution.'

In my home state of Delaware, we've done our homework and worked hard and, as a result, we've made great strides in cleaning up our own air pollution. Unfortunately, a number of the upwind states to the west of us have not made the same commitment to reducing harmful pollution by investing in cleaner air.
