Another collective delusion is the overpopulation we are experiencing. And it's accelerating. 8 billion people now. Global population was 1.6 bil 100 years ago. Let that sink in. It is a massive problem because due to advertising and media every one of this 8 billion wants to live like a first world middle class person. It is not sustainable.

Check out how population growth rates level off as people get to “first world middle class person.”

5 days ago, not sure how I missed this one before.

So a few points on this:

1. Depends how you define overpopulation. Can we still feed all of us? Yes. Do we? No, because while we can easily grow enough food, 50% more than our current population at least, people still starve, just not due to lack of food in the world. I think when we get to the point that we’re seeing a mass die-off of humans because of resource exhaustion, you can start calling us overpopulated. This is not to discount the possibility that we may become overpopulated, but I don’t think we know where that threshold actually is yet.

2. That said, population does tend to level off once the people of a country are well off enough, and so some countries are facing population contractions. Even within countries which are technically growing, subsets of their populations have leveled off and part of the difference is being made up in immigration. We may never actually reach overpopulation if that trend continues.

3. This is the part I hate when discussing population concerns. Let’s throw away my arguments above that we are probably not overpopulated, and suppose you are right. Then what? Genocide? Eugenics? Voluntary societal suicide either directly or by mass scale vasectomy? Just do nothing until something gives?

Acceptance of the idea that there are too many people leads you down to a much more uncomfortable conversation.

Also: all of this is off-topic. San Francisco could support plenty more people. Both California and the United States grow enough food to be net exporters, and California specializes in cash crops. Doing so would require upzoning. Upzoning would lead to neighborhood change, and that’s really the thing San Franciscans are fighting against. Every single time the Earth’s population vs carrying capacity is brought up in the context of San Francisco’s seeming inability to build more homes, it is a distraction.

We could, but we make it as difficult and expensive as we can to keep people out because San Franciscans taken as a whole don’t like outsiders and don’t like change. We’re not the only populace or locality that doesn’t like these things, but we are some of the whiniest and most hypocritical.
