The sheer quantity of chemicals being dumped into the environment is quickly growing—and we only be seeing the beginning of the harm they are doing to us.
Even species in the remotest regions of the planet are suffering serious chemical contamination. A female orca carcass that washed up on a beach in Scotland in 2017 was found to have. Scientists who examined the whale’s ovaries say she had never been reproductively active, though she was at least 20 years old. Orcas usually start mating at 14.
Meanwhile, we humans must come to terms with a confusing reality in which we face the seemingly contradictory risks of both overpopulation, which is contributing to environmental ruin, and a population crash due to chemical-induced reproductive problems. It’s easy to dismiss one by pointing to the other, but we must somehow grapple with both.
, only a tiny proportion of which have been tested for safety, are making their way into the environment—from pharmaceuticals that have passed through human bodies, to plastics, pesticides, solvents, fire-retardants, and chemicals used in making cookware coatings. While the reasons for falling sperm counts are still being investigated, it is clear that the fetus is particularly susceptible to the effects of pollutants, and that impacts at the fetal stage of life can significantly shape the adult. The pollutants most likely to have widespread impacts on reproductive health have been identified—hormone-mimicking chemicals that have become widely dispersed in the environment, many of which persist for decades or longer.
