Adding mercury to any body is damaging.
Adding mercury to a toxic body can be deadly.
Choosing seafood to add to your diet
takes a bit of planning.
In the case of lake or stream fish, consider which fish might be stocked species. Fish provided for stocking are generally farmed and this most likely means they were fed GMO feed. GMOs, genetically modified organisms, bring a new set of problems to the human body. To research GMOs see the link below.
Our fish are mercury polluted for many reasons. Its natural occurrence on earth is not the primary issue with human contamination. Two of the greatest sources of mercury contamination in the USA are caused by humans. The water waste run-off from dental offices that runs into our waterways and oceans is a major concern.
Additionally, air pollution from crematoriums (when cremating "silver" fillings) carries mercury through the air to be deposited eventually into ground and water resources.
