In the early 1900s, coal miners used birds in cages to monitor air safety and alert them when they were inhaling noxious gas while they could still act to save themselves. Today, researchers are studying pet dogs to learn about the chemicals that men are exposed to at home in search of warning signs that human health may be at risk.

Within just a few generations, human sperm counts may decline to levels below those considered adequate for fertility. That s the alarming claim made in epidemiologist Shanna Swan s new book, Countdown , which assembles a raft of evidence to show that the sperm count of western men has plunged by over 50% in less than 40 years.

Health by Ben Graham 16th Apr 2021 6:51 PM In merely a few generations time, the human race might find itself at a moment that could spell the end of our species. As sperm counts decline to levels below those considered adequate for fertility, we may no longer be able to reproduce unless drastic lifestyle measures are taken to reverse this trend. That s the chilling warning from a leading reproductive epidemiologist at New York s Mount Sinai, Dr Shanna Swan, a Professor in Environmental Medicine and Public Health, who says the sperm count of Western men has plunged by over 50 per cent in less than 40 years.
