> Microplastics (MPs), which are smaller in size and difficult to degrade, can be easily ingested by marine life and enter mammals through the food chain. Our previous study demonstrated that following acute exposure to MPs, the serum testosterone content reduced and sperm quality declined, resulting in male reproductive dysfunction in mice. > [...] In summary, our study showed that chronic exposure to PS-MPs resulted in toxicity of male reproduction under environmental exposure levels, and these potential risks may ring alarm bells of public health. https://particleandfibretoxicology.biomedcentral.com/articles/10.1186/s12989-022-00453-2

I don't understand what you're getting at. what? get rid of BPA, and do something about plastic pollution? what's the solution to fix the apoplexia? what're we solving, here, op?

@previous (spectacles) > get rid of BPA, and do something about plastic pollution?
That'd be a start. Further research on their effects, ways to counteract them, and ways to degrade them. And of course finding and discovering alternatives to plastics that share some of their many benefits.
But not all of what I mentioned here is about plastics. Birth control and fertilizers may have just as significant of an effect.
> what're we solving, here, op?
Hopefully many problems that might be a consequence of endocrine disrupters in our environment and food. Metabolic syndromes, the rise in obesity, the rise in fertility problems all across the world, the rise in gender dysphoria, and so on. Are these not worth solving, looking into, or at least discussing?
Say, are you familiar with the history of lead, particularly in the US?

@previous (A)
what antagonism? acknowledging your contribution to resolving systemic environmental and sociological problems is antagonism? I said cool beans. I'm just asking about lead cause you brought it up, why are you getting defensive about having a discussion? I'm just asking questions, did I do something wrong?
