Does a grizzly bear die of too much mercury?

Yes, grizzly bears can suffer from Mercury poisoning, which can be harmful or even fatal. Mercury accumulates in the food chain, particularly in fish, which are a significant part of a grizzly's diet. High levels of mercury can lead to neurological and reproductive issues, affecting the bear's overall health and survival. However, it is not common for grizzly bears to die solely from mercury exposure.
