Completely disagree. Tje richest 10% of the world is responsible for 50% of CO2 output. I don't know about other metrics, but that I'm sure that pattern isn't just limiter to carbon footprint. We don't have a population problem. We have a problem with Greer and resource use that slashing ourr population - even drastically - will not in any way solve.

The richest 10% of the world also come from regions with stable-to-negative population growth. Those regions are our only hope for moving to a sustainable technological platform while maintaining a high quality of life; we're talking about the people who buy solar panels, windmills, and electric cars, who at least can build nuclear plants, if they get over their political reservations.

The poorest 50% of the world would absolutely love to emit more CO2, and will do so just as fast as they can acquire the resources.

I don't think any steps to limit population growth really need to be taken, however, other than two things which are good in and of themselves: women's education, and improving access to birth control.

But concerns about Earth's carrying capacity need to be taken seriously. Malthus is wrong right up until he isn't, and we should strive to avoid hitting that limit.
