Plastic pollution could make much of humanity infertile, experts fear

Since the start of the 2020s, humanity has faced worldwide calamity after worldwide calamity, all of them raising questions about our survival as a species. The COVID-19 pandemic has already claimed millions of lives and not yet finished its rampage. Russia’s invasion of Ukraine has raised the specter of nuclear holocaust, which many assumed has subsided with the end of the Cold War. Even as these problems worsen, climate change continues to quietly creep along in the background, overheating the planet for future generations.

Yet what if, on top of all these things, there is an even more dystopian crisis in the offing — one in which humans are no longer able to reproduce without artificial help because we have filled the environment with chemicals that have altered our bodies?

Scientists believe this is not only possible, it is likely to happen within our lifetimes.

Understanding why involves three statistics: First, that a human male who has fewer than 15 million sperm per milliliter is considered infertile; second, that in the 1970s sperm counts in Western countries (where there is available data) showed an average of 99 million sperm per milliliter; and third, that this number had dropped to 47 million sperm per milliliter by 2011. Scientists agree that plastic pollution is a likely culprit.

The trailblazer here has been Dr. Shanna Swan, a professor of environmental medicine and public health at Mount Sinai School of Medicine in New York City, whose most famous book has a conveniently self-explanatory title: “Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race.”

The main culprit is believed to be chemicals within everyday plastics known as endocrine disruptors. These chemicals, including a range of phthalates and bisphenols, are literally inescapable. They can be found in the dishware, food cans and containers from which you eat your food, and in the water bottles and other plastic receptacles from which you drink. They are in virtually all of your commonly used household electronics, your eyeglass lenses, your furniture and even on any commercial receipts that come from a thermal printer. Because endocrine disruptors are in pesticides, they have also entered the foods that we eat thanks to the agriculture industry. Even without pesticides, though, we would still wind up eating these endocrine disruptors. Microplastics — that is, plastic particles which are five millimeters or less across or in length — have entirely covered the planet. Animals accidentally eat microplastics all the time and plants regularly absorb them through their roots. Humans themselves ingest the rough equivalent of a credit card’s worth of plastic each week.
