The tinfoil hat resurfaces!
According to this article in the Guardian, man made chemicals are disrupting the male/female ration of babies being born in the Northern Hemisphere. It has gotten so bad the farther North you travel (apparently some of these compounds are carried by wind) that some areas of Russia, Greenland and Canada are having twice and many female offspring as male. And, in one Inuit village, they are ONLY HAVING GIRL BABIES now. These chemicals really concentrate in their traditional diets that are heavy in larger ocean animals and meat.
