- jhayward 6y agoHave you ever wondered why you can't eat fish caught in wilderness lakes over much of the American west? Because of mercury levels, courtesy of coal-burning power plants. It goes up the smokestack and lands in the food chain. This is also why people are advised to limit consumption of ocean-caught salmon, tuna, etc. - they have high mercury content, almost entirely thanks to coal plant smokestack emissions.
