*sigh* This is easily all debunked using some simple common sense:-
1) A youtube video has far, far less credibility than a scientific study featured in prominent scientific magazines, like the long-lasting Rochester University Seychelles study. In the case of the latter study, it showed conclusively that Seychelles islanders (who eat 10 times as much seafood than the average American) did not get any health-problems at all, however minor, from all the mercury they ingested. Indeed, if you checked that study, you would find that the relevant children actually gained a bit in terms of neurological activity.Also, bear in mind that the youtube video scientists merely talked extremely vaguely about levels of pollutants existing in every human body. What they conveniently neglected to mention is that each human body contains microscopic amounts of almost every toxin in the environment, such as uranium, for example -yet, mysteriously and hypocritically, none of the anti-mercury people go on about uranium and all the other harmful substances that have been present in human bodies since the dawn of time in microscopic amounts found in nature . Now these levels are in such tiny amounts that they have no effect on the human body. Then there is the fact that those denouncing mercury will not admit that government RDA levels/targets are completely arbitrary and usually set way, way below the actual threshold where harmful symptoms start appearing,just so as to avoid any chance at all of potential side-effects.
3) Mercury-amalgam/vaccines issues. These have been comprehensively debunked by numerous studies, so waste of time to bring them up. I also had my mercury fillings removed - that did nothing for me. Granted, some people will always feel a fake placebo-like effect after removal of mercury amalgams, but that means nothing, of course.
4) AV has no proof re his contention that raw fish protects against mercury. Maybe a tiny bit, perhaps, but the Minamata Bay Incident( the japanese prefer eating their fish raw) shows that a diet consisting partially of raw seafood is no protection against mercury when it is dumped in the form of many thousands of gallons into a bay.
