More of Malthus
I was trying to make two points in my earlier Malthus post. Judging by the responses, I didn't make them very convincingly. So here is another try:
1)Measures to decrease death rate may have the unintended consequence of later decreasing the welfare of the consequently more numerous survivors. I think that happened especially in Africa and Asia.
2)There are limits to how many people the planet can support.
I would add my view that hitting the limit is likely to be catastrophic.
