Not really. They layer some dystopia controlling the increased population having more services and choices. Eventually renaissance becomes catastrophe. It did with Sodom and Gamorrah, Pompeii, the Mayans, and so many more. But this is from a growing population expanding, and the technology surpassing it, depleting resources quicker, causing a host of geography and geopolitics.

But technically they're not depopulation, they're a result of increased population. Population eventually tips whatever its sexual appetite. The more it grows the greater its problems. Nature eventually answers back, human, conflict is our nature, we are individuals who make our own choices, or planetary, the greater a species numbers the more they threaten the natural habitat. Increased sexual appetites can bring diseases. A case whatever your fetish. But conceptually you're wrong to assume depopulation. Opposite by fact, a result of population.

An easy assumption because they cannot birth, without more services, adoption, surrogacy, whatever. Why did they need too, when there was that increased population having more choice promoting them? Too control it. Yawn. It would gain no matter what gets fucked. Until it tips, no matter what.

Not promoting them, don't care, dispelling that myth. A result of increased population. Otherwise simple fact, they wouldn't sustain. Imagine it in the Wild. There's Ham sent into the Jungle.
