One could make the point this is less about industrialization causing a change in behavior, and more chemical pollution destroying fertility. Of which we have plenty of concrete evidence.

Except evidence does not show that there are many more people trying and failing for kids as in past decades, so much as more people are delaying partnering up and having kids till later and later, along with many opting to be childless.

And most fertility issues people do encounter can primarily be explained by attempting to have children decades later than is biologically optimal.
