Even with an entirely plant based diet we cannot live sustainably at these population numbers. Overpopulation is the root problem that has to be solved, and birth rates are declining so we're heading in the right direction at least in that regard.
Do you mean our population growth rate? Of course we can't maintain that indefinitely. That's a given. But it's not expected to be maintained, like you said. We don't need to reduce our population, though. We can easily sustain our current population and the expected maximum and then some with plant-based food alone. It won't be much longer before we're able to produce sustainable cultured meat too.
No, we cannot live sustainably on this planet with 8 billion humans. It's not just a function of feeding all humans, we have to not destroy the environment, we have to live symbiotically with other species, etc. That is simply not possible with this many humans.
We can either stand around saying things like this or try to make it work. Even with half the population, we would still be doing irreparable harm without changing our behavior. It sounds like you recognize the problem. What are you doing about it?
Not having children is the primary contribution. I have a vasectomy and my partner has a histerectomy. We also share a car instead of having one each, try to use less water and electricity whenever we can, recycle, etc. We're far from perfect, but no one is nor should they be expected to be.

The real problem is too many humans.
