A Common Herbicide Turns Some Male Frogs into Females: Scientific American
This is very much a human problem. Men and boys are increasingly suffering the effects of estrogenization. Male fertility is declining. 100% of the human population is affected by endogenous toxins. Plastics and a pharmaceutical soup are in our water supplies. The air and soil are also dumped on with hundreds of thousands of tons of chemicals and pollutants every year. The human body often has no way to break these toxins down so they either circulate perpetually or get stuffed in joints and fatty tissue. Think brain problems today. Think about the rise in brain related diseases and breast cancer, both largely fatty tissue. Think cancers and auto-immune diseases.
It is imperative for everyone of us to do whatever we can to detox. Avoid chemicals as best as possible. Look into a detox diet and nutrients.
