Below replacement birth rates in 1st world societies seem to disprove the idea that humans inevitably expand to the point of environmental collapse.
Further, having as many children as the environment can support, regardless of the consequences for the environment or its destruction, is natural for nearly every life form. Look at invasive species like Asian carp or zebra mussels.

As a story in GQ noted earlier this year, a widely cited study published in 2017 by researchers from the Hebrew University and Mount Sinai’s medical school found that among nearly 43,000 men from North America, Europe, New Zealand, and Australia, sperm counts per milliliter of semen had declined more than 50 percent from 1973 to 2011. And not only that, “but total sperm counts were down by almost 60 percent: We are producing less semen, and that semen has fewer sperm cells in it,” wrote the GQ contributor Daniel Noah Halpern. When Halpern asked several scientists why, they presented a united front: It was the unprecedented amount of chemicals now routinely entering the human body.
