I've heard that before, but I haven't looked into it. I suppose Cnut247 will come up with some data on the subject.

But one thing is clear: a lot has happened since Malthus, who, for those who don't know, predicted a catastrophe in which there would not be enough resources to feed a growing population in the world, and the fact is that the population has continued to grow and grow, while more and more people eat more and more. There is a global obesity problem even in countries where relatively recently many people were going hungry: China, Mexico, etc. It is clear that you cannot grow to infinity, but it is also clear that Malthus was wrong.

There have also been failed predictions about climate change. This does not invalidate the model either, there could be certain wrong predictions and the global model could be correct, but it seems to me that it is a complex subject with so many variables that make it difficult to get the predictions right.
