A recent study done by the U.S. Geological Survey (USGS) showed that 100 percent of the 291 freshwater fish tested contained mercury contamination. Of these, 66 percent had levels higher than the "level of concern" set by the Environmental Protection Agency.

This strikingly high number sets a new standard for how concerned Americans should be about mercury in fish. Mercury can have devastating effects on young children, but in high levels can also affect older adults.

Mercury pollution occurs almost entirely from air-born emissions, primarily burning coal. We need to stop this pollution at the source before we start to see improvements in contamination levels.

The Environmental Protection Agency (EPA) is responsible for regulating industrial mercury from factories and plants. Please tell EPA Administrator Lisa Jackson that mercury levels should be strictly regulated. We can't get much worse than 100 percent.
