The informational part is the excellent ( ) The author explains that chemicals used in plastics, cosmetics, and pesticides are toxic to our reproductive systems and those of animals. There are detrimental effects on spermatozoa and on reproductive health at all stages of life. The author suggests that we decrease the amount of these chemicals in our environment and that we promote this change. It is an interesting and concerning issue. The book is well written and understandable. Alarming. Maybe. Full disclosure up front: I'm not overly concerned about human extinction. But for those that might be concerned that it might be possible... you're probably going to want to read this book. Swan has spent a lifetime studying human reproduction, and the data she presents here is genuinely startling. I fully admit I am no expert here, but her case is well documented, sometimes with pages of footnotes at the end of each chapter and with a bibliography roughly 1/3 the total page count of the book. Which is average ish for a well-documented science book in my experience. Really the only quibbles I have with the book at all truly are completely philosophical. As I said, I'm not actually concerned about human extinction, and in the final chapter before her conclusion, Swan calls for a number of government actions... and I'm an avowed anarchist. ;) That said, this text is a very clear example of the need for leaders - and even individuals - to listen to subsystem experts (in thie case, human reproduction) but be aware of how recommendations from those experts about their subsystems could lead to disastrous results in other areas, and work to address the concerns of the experts while avoiding the outside disastrous outcomes. Still, for the hard science that the bulk of the text shows here, this is truly an excellent read. Very much recommended. no reviews | add a review
"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 45,000 healthy men. The result sent shockwaves around the globe-but the story didn't 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 development-potentially including the increase in gender fluidity-and 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 at once an urgent wake-up call, an illuminating read, and a vital tool for the protection of our future"-- No library descriptions found. |
