Since it seems like you just don't get it, let me give you an analogy that might be more accessible.

We are in a car rocketing towards a brick wall at 100 miles an hour. We can slow down gradually (controlled population decline) or we can slam into the wall (unsustainable agriculture practices turn the earth into a toilet, sudden mass starvation, civil unrest leading to the collapse of civilization).

You seem to be under the enchanted fairy tail notion that there's an exponential curve of infinite resources just awaiting the power of human cleverness to save us from this grim fate, but I'm sorry to inform you that's delusional. You can see clearly that most areas of human technology are already in the logarithmic portion of the (sigmoidal, not exponential) progress curve, and those areas that are still in the exponential phase like AI aren't going to magically transform agriculture.

The shear volume of food that is left to rot in fields, in storehouses, in American pantries, suggests to me that there's a lot of slack in the resource chain before we actually face mass starvation. People are starving to death in places like Somalia or Haiti right now specifically because there's no profit to be made selling them food that's already grown and been harvested. We could afford to cut back food production, switch to less productive (but less destructive) farming practices if we were just willing to ship the food to where its needed, irrespective of profit. I don't disagree, we're heading towards a resource cliff, but I do not think even for a second, that the Earth is incapable of supporting 10+ billion people, even with much more constrained growing capability. The constraint on the food supply is that there are huge swaths of the global population that are unprofitable to feed. And that's really where you're catching flack. We don't need population control policies. We need to stop deciding that selling food at a loss is worse than letting children starve.

If you're concerned about overpopulation being a drain on food resources, then you should be agitating for overall better living conditions, better access to healthcare, better access to education in the global south. We have seen repeatedly that a healthier, happier, better educated society has a lower birth rate.

I get your argument, it's just morally reprehensible. Your analogy about a car is not related and shows weak reasoning.

> You seem to be under the enchanted fairy tail notion that there's an exponential curve of infinite resources

Resources are definitionally raw materials coupled with human ingenuity.

> You can see clearly that most areas of human technology are already in the logarithmic portion of the (sigmoidal, not exponential) progress curve

I don't see this at all. This is just your opinion.

You're essentially talking about starving people on purpose, "controlled population decline" is eugenics and you should take that nonsense somewhere else. Seriously your ideas are disgusting.
