Here's a pretty terrifying statistic: 100 percent of the fish tested by the U.S. Geological Survey in nearly 300 streams were found to be contaminated with mercury.
Every single one.
Between 1998 and 2005 scientists tested over 1,000 fish from 291 streams across the country and found mercury in all of them. A quarter of the fish had more than the EPA thinks is safe for people to eat.
We can thank coal for this one. Mercury is found in coal and is released from power plant smoke stacks into the air. It eventually comes back down to earth in rain and other precipitation and travels through the food chain to collect in the fatty tissues of, apparently, every fish living in the United States (and any person eating those fish).
How do you like them apples?
Coal is the enemy of mankind and looks to be no good friend of fish either. We need to stop burning it post-haste.
