They showed reduced sperm count in a dose-dependent manner in dogs. More plastic, less sperm.<p>And then a higher plastic concentration on average in human testis.<p>Wild.
it’s everywhere and in everything. banning single use plastics and car tires is placebo because you will still be getting microplastics in meat, vegetables, and water for hundreds of years at this point.<p><a href="https://www.theguardian.com/environment/2022/jul/08/microplastics-detected-in-meat-milk-and-blood-of-farm-animals" rel="nofollow">https://www.theguardian.com/environment/2022/jul/08/micropla...</a><p>there are too many people on this Earth and the population numbers are propped up by our usage of plastics.
Is there any question at this point that plastics are the next lead paint / asbestos? We should be moving to ban single use plastics, especially in products consumed by humans.
I was a little surprised that the values are higher for humans than dogs b/c I am used to seeing dogs gnaw on any random thing, trying to drink from puddles, etc, which I would have thought would lead to higher intake. But ... is it just that this is these bioaccumulate and humans live longer and eventually have higher levels? Or do people actually have a higher intake through e.g. hot beverages in lined disposable cups, plastic cutlery and takeout containers, etc?
