The effect of hormone disruptors was first noticed in wildlife, but is now being observed in humans, for example, in the worldwide decline in sperm count.
Over 100,000 synthetic chemicals are now in widespread use but this is still very recent in terms of evolution.
It has been more than 80 years since toxic chemicals such as PCBs and DDT were introduced. The first generation of children exposed to these chemicals in the womb has recently reached reproductive age, and we are seeing more and more hormone problems and infertility. In fact, most people have been exposed to dangerous chemical toxins throughout their life.
