Danged hippy, pinko-commie, running-dog, anti-American, anti-capitalist, fear-mongers. Everyone in their right minds knows mercury is good for you, especially for babies and kids.
You’re breathing it in right now. Go outside and pickup some soil. Analyze it if you wish. You will see concentrations so high it would literally take a coal fired power plant 9,000 to 14,000 years at the max deposition rates to put that much mercury in the soil.
Methylmercury accumalation in fish has nothing to do with power plants. You can’t even see the power plants mercury concentrations in the air...it’s all noise.
