By 1990, the EPA had tallied up 32,645 sites of past chemical waste dumping in need of cleanup. Some of these are actual waste landfills, but many are former manufacturing sites where drums full of chemicals have been simply abandoned. The names of the most notorious appear on the EPS's National Priorities List. These are the so-called Superfund sites, names for the super fund of money put together by Congress in 1980 to clean them up. In 2009, the Superfund list contained 1,331 sites.

I have always been a big advocate of tap water-not because I think it harmless but because the idea of purchasing water extracted from some remote watershed and then hauled halfway round the world bothers me. Drinking bottled water relieves people of their concern about ecological threats to the river they live by or to the basins of groundwater they live over. It's the same kind of thinking that leads some to the complacent conclusion that if things on earth get bad enough, well, we'll just blast off to a space station somewhere else.

From the right to know and the duty to inquire flows the obligation to act.

We can decide that the presence of cancer-causing substances in our air, water, and food is too expensive. A 2009 study, for example, has found that coal miners in Appalachia costs the region five times more in premature deaths, including from cancer, than it provides to the region in jobs, taxes, and economic benefits. In California, the production and use of hazardous chemicals cost the state $2.6 billion in 2004 alone in lost wages and health-care expenses to treat workers and children with pollution-linked diseases.

We are all musicians in a great human orchestra, and it is now time to play the Save the World Symphony. You are not required to play a solo, but you are required to know what instrument you hold and play it as well as you can. You are required to find your place in the score. What we love we must protect. That’s what love means. From the right to know and the duty to inquire flows the obligation to act.

I have come to believe that extracting natural gas from shale using the newish technique called hydrofracking is the environmental issue of our time. And I think you should, too.

The scientific analysis that is supposed to provide our Governor the facts and information he needs to make a crucial decision was crafted with the guidance of the gas industry, not of the state's scientists.
