just dont drink any seawater or local fish
i would bet the fish from those polluted farms in Vietnam are safer than the Japanese fish now
also, DO NOT DRINK the tap water in China!
Hong Kong took better care of their water than Beijing, so, BE WARNED: THERE IS A REASON THEY DRINK TEA; IT IS BOILED FIRST!
boiling doesnt get rid of toxic pollutants.
they boil their water because traditionally their water treatment methods weren’t very sophisticated. They also don’t trust water thats been sent through many miles of pipe to still be clean
