description: In the tradition of Silent Spring and The Sixth Extinction  an urgent disturbing empowering and essential ( Kirkus Reviews  starred review) book about the ways in which chemicals in the modern environment are changingand endangeringhuman sexuality and fertility on the grandest scale from renowned epidemiologist Shanna Swan.In 2017 author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45000 healthy men. The result sent shockwaves around the globebut the story didnt end there. It turns out our sexual development is changing in broader ways for both men and women and even other species and that the modern world is on pace to become an infertile one.How and why could this happen? What is hijacking our fertility and our health? Count Down unpacks these questions revealing what Swan and other researchers have learned about how both lifestyle and chemical exposures are affecting our fertility sexual developmentpotentially including the increase in gender fluidityand general health as a species. Engagingly explaining the science and repercussions of these worldwide threats and providing simple and practical guidelines for effectively avoiding chemical goods (from water bottles to shaving cream) both as individuals and societies Count Down is staggering in its findings (Erin Brockovich The Guardian) and will serve as an awakening ( The New York Times Book Review ).
