Given human exposure to dioxin-like chemicals, for example, it is probably that some humans, especially the most sensitive individuals, are suffering some effects.

For example, the Scottish study conducted by the Medical Research Council's Reproductive Biology Unit in Edinburgh on a sample of 3,7299 men found a median sperm count of 128 million per milliliters in semen donor born in 1940 but a median count of only 75 million in those born in 1969.
4. "Because total estrogen exposure is the single most important risks factor for breast cancer, estrogenic chemicals, which would add to this lifelong exposure, are an obvious suspect when searching for the cause of rising rates over the past half century. "182
This quote reveal the number 1 cause of Brest cancer, estrogen exposure. Since 1940, when the chemical age was drawing, breast cancer deaths have risen steadily by one percent per year, in the United States, and similar increases have been reported in other industrial countries. Such incidents rates are adjusted for age, so they reflect genuine trends rather than demographic changes such as a growing elderly population. Among American women forty-five years of age, breast cancer is now the leading cause of death.
