There is no evidence in the linked text that possible "reproductive issues" from sperm count reduction would be something overall bad. One possibility is that the total number of humans born will decrease somewhat and that global population will be somewhat lower compared to an alternative scenario with less microplastics. Every human has needs that require energy and resources so a scenario with lower global populat…
> might be better in terms of making sure all born humans get what they need. Might be. Or might not be. Who knows? Let's leave it up to random chance and see what happens! No point in trying to understand this phenomenon right?
On current projections human world population peaks at 10 billion in 2086 [0]. If, for the sake of argument, microplastics were to lower reproduction somewhat so that "only" 9.5 billion people came to exist in 2086, would that be bad? We're already putting a lot of pressure on many of earth's scarce resources in ways that have harmful effects on the welfare of many existing humans. Increasing population increases that pressure.
