I do believe a large amount of people, in the world, think ressources will never lack. Another large amount of people do not care, and those who believe we "have a large reserve of productivity to feed both economic and demographic growth for the foreseeable future" are behaving as if there was no limit.
So whatever their belief, there is no qualitative difference between the three groups.
You need to feel constrained to act.
We have a false sense of abundance in the west, as we are draining ressources away from developing countries and our infrastructure is more robust. 2008 was also a major food crisis for the majority of the world population: https://en.wikipedia.org/wiki/2007%E2%80%9308_world_food_pri...
Although it was not felt in developed countries, the tension is real, on a very large scale.
The worst are religious natalist, and preachers of morality, who oppose beyond logic any proven fact about the state of the world.
You see homeostasis everywhere in living organisms, dynamical systems converge to energetic minima, to believe our ingenuity will allow us to fix as we go the complex system that is Planet Earth is reckless. To think we are not as fragile as the weakest link in the food chain is foolish.
