Ein hier in den Kommentaren verlinkter Bericht über sinkende Spermienzahlen:
The end of humankind? It may be coming sooner than we think, thanks to hormone-disrupting chemicals that are decimating fertility at an alarming rate around the globe. A new book called Countdown, by Shanna Swan, an environmental and reproductive epidemiologist at Icahn School of Medicine at Mount Sinai in New York, finds that sperm counts have dropped almost 60% since 1973. Following the trajectory we are on, Swan’s research suggests sperm counts could reach zero by 2045. Zero. Let that sink in. That would mean no babies. No reproduction. No more humans. Forgive me for asking: why isn’t the UN calling an emergency meeting on this right now?
The chemicals to blame for this crisis are found in everything from plastic containers and food wrapping, to waterproof clothes and fragrances in cleaning products, to soaps and shampoos, to electronics and carpeting. Some of them, called PFAS, are known as “forever chemicals”, because they don’t breakdown in the environment or the human body. They just accumulate and accumulate – doing more and more damage, minute by minute, hour by hour, day by day. Now, it seems, humanity is reaching a breaking point.
Swan’s book is staggering in its findings. “In some parts of the world, the average twentysomething woman today is less fertile than her grandmother was at 35,” Swan writes. In addition to that, Swan finds that, on average, a man today will have half of the sperm his grandfather had. “The current state of reproductive affairs can’t continue much longer without threatening human survival,” writes Swan, adding: “It’s a global existential crisis.” That’s not hyperbole. That’s just science.
As if this wasn’t terrifying enough, Swan’s research finds that these chemicals aren’t just dramatically reducing semen quality, they are also shrinking penis size and volume of the testes. This is nothing short of a full-scale emergency for humanity.
Irgendwie habe ich ähnliches immer wieder mal gelesen und ich meine auch der erste Bericht war lange genug her, dass eigentlich das Ende der Menschheit schon dargewesen sein müsste.
Die Methode aus einem Absinken einfach hochzurechnen halte ich auch nicht für sehr seriös. Aus einem bestimmten Absinken durch bestimmte Stoffe kann nicht geschlussfolgert werden, dass es auch weiter absinken wird. Vielleicht ist die schädigende Wirkung in der Hinsicht bereits ausgereizt.
Das bedeutet nicht, dass man sich des Problems nicht annehmen soll. Aber gleichzeitig habe ich ein gewisses Mißtrauen gegen solche „Wir sterben alle aus“-Botschaften
