Even people who are healthy and athletic can be affected by air pollution.

It (ozone) doesn't occur every day, and it's very measurable. It's easy to get information about concentrations.

The Bay is cleaner than it was 40 years ago when raw sewage and industrial pollution were dumped directly into it. While the pollution from business and point sources is strictly regulated, storm water pollution from our cars, homes and neighborhoods is still a major problem.

I always start by telling people this is not a silver bullet. It will not eliminate water pollution from farm runoff, but it's one more layer of technology to address the problem.

Governments, industry and people everywhere have to start reducing fossil fuel pollution as if our lives depended on it. Actually, the very survival of tens of thousands of species does depend on action to avoid dangerous climate change.

We in Government have begun to recognize the critical work which must be done at all levels--local, State and Federal--in ending the pollution of our waters.
