Fish do not have much more mercury now than fish hundreds of
years ago, according to an article I read. Can't blame
everything on humans.
There is another point that needs to be considered too.
Animals do concentrate some poisons, such as mercury. But
the opposite effect also occurs. Animals DEtoxify many foods
which we can not eat directly. Animals filter dangerous
chemicals out far more than they accumulate them.
Humans have been at the very top of the food chain for a
long time. We, and all carnivores, are adapted to this
position. Our bodies are designed to filter out dangerous
elements, as long as we are eating the food we are meant to
eat. Meat.
