I don't think so.
Recall all the howling and wailing over peak oil? And then there was no such thing as peak oil?
Or the predictions that we'd run out because there are not more dinosaurs to ferment into oil Except oil is a mineral product from geology, not fossils.
We have done ourselves ( or rather our bretheren in poorer countries) some serious disservice by augmenting their food supplies and giving them medicines and medical care helped them learn how to get water, and all that helped them produce more (lots and lots more) fat happy babies.
Who doesn't like babies?
And now when times get hard and we can't give so much away (like during Covid) they all starve back to the sustainable populations that they they had before we meddled in their lives. It's ugly.
But we don't occupy much more than a lousy 10% of the earth so we are no where near maximum population density.
But you should be cheered. Japan's birthrate has fallen off a cliff and so too in Europe and the USA. Even Friggin China has seen it's birth rates fall. People have become so massively selfish that they won't have children.
But to your point more directly:
If humans become a burden on the planet, humans will develop a technology that can alleviate that burden just like we did with peak oil. That's how capitalism works; see a problem, fix it, and sell the cure.
But this girl seems to have the solution
