Malthus was wrong. We keep finding ways to carry on. I still worry that we will hit a limit we cannot get past. We have never before had such globally integrated systems. If we sort out CO2, we have rising incomes in China and India and Africa who collectively are already more than half the global population. Their consumption matters more than mine for the future of us all. One global pandemic will cause economic havoc, even without Thanos.

Given current trends, sure. No need to panic. We are trending towards survival for the moment. But the future will bring the gradual or sudden decline of our now global order if we cannot live within our means in terms of resources. Can technical change keep up with our needs? So far, yes. But it is not guaranteed.

Civilizations can and do collapse. Ours is not immune. We are vulnerable. People are right to be concerned. It is not anti-science to question tbe status quo. It is the whole point of science to ask questions, and look for better data to find better answers.
