I asked up thread what percentage of GDP would need to be retasked to get us on to a sustainable path. Forbidding people from doing harm is only half of the solution, because we also want to allow people to do the things they want to do and to achieve better comfort per unit work.
Some people think it could be done with the profits that they don't see, ignoring the ginormous profits they do see that are unsustainable.
Nearly everyone will, given the choice, vote to increase net destruction in exchange for short-term gratification. And they will vote that other people can't. And then they'll argue why their choice is okay, but no one else's is. And because the damage is being measured at the statistical level, everyone can let their eyes glass over and ignore the fact that damage is fungible and spending needs to be counted twice when talking about efficacy.
There is a political argument. But even that can only go so far. You can eat at ethnic restaurants all you want in order to be non-racist, but no amount of restaurant eating will stop the Revolutionary Guard from beating women.
The thread is about overpopulation. Both China and India have stopped exports of food along certain dimensions. Sure, there are Western companies that are currently selling food into China that are unsustainable. But these regions have also grown from historical populations to where they need imports during a shock.
Think about a counterfactual, where no region was desperate for imports. Obviously, that counterfactual is less overpopulated. But as soon as you have regions that are desperate for imports, you know that there's a warning sign. Redistribution is obviously a potential solution, but it's obviously less optimistic.
Overpopulation is an interesting state of being. When I put the third dozen fish into an aquarium, it's overpopulated as soon as I put them in. But you prove that the overpopulation has occurred once they start dying. The person running the experiment tends not to suffer anywhere nearly as much as the entities who test the question.
