This is a major flaw in science and basic economic comprehension. You could grow enough potatoes to feed the world enough calories with just the area of France. We could build huge apartment blocks surrounded by farmland and connected via tiny mono rails. We could build apartments and appliances and computers that last for a century. We could genetically engineer microalgae to taste like pancake butter. If we half the number of required workers, we'd save a mountain of resources on commute. We could design everything to be recyclable. Wind energy with Kites Power gives us near unlimited energy. Our footprint could be tiny but with the luxury of free time, learning, arts and living in a community and in nature.
We are nowhere near carrying capacity, we're just over because we waste so much on consumerism, planned obsolescence, unsustainable crops and artificial scarcity.
Our civilization is a fucking joke but science treats current conditions as if they were normal and immutable.
