The models from "limits to growth" have been disproved? This would be good news. Please post a link.

Last time I checked, the models presented in the "Limits to Growth" seem to be tracking the situation pretty well. Here is a paper about it (not mine) https://sustainable.unimelb.edu.au/__data/assets/pdf_file/0005/2763500/MSSI-ResearchPaper-4_Turner_2014.pdf https://sustainable.unimelb.edu.au/__data/assets/pdf_file/00...

  It predicted running out of oil in 1992, for example. Besides, we will never run out of oil, just like we never ran out of wood nor whale oil.

Don't need a link, here's a quote directly from the book: "there will still be a desperate land shortage before the year 2000 if per capital and requirements and population growth rates remain as they are today." pg 60 It's 2018. Where's the desperate shortage? Also on HN today is talk about the new "vertical farms" that use far less resources than flat farms.

population growth has considerably decelerated, the model in limits to growth was based on continuing exponential population growth. Check out the population growth chart at https://ourworldindata.org/world-population-growth https://ourworldindata.org/world-population-growth - the growth rate has plummeted drastically. We still have an estimated few billion more to add before the growth rate hits 0 but we won't be facing the kind of drastic overpopulation that limits to growth accounted for.

  The trouble with TLTG is it simply extrapolates existing trends. This makes for great headlines, but as any economist knows, any businessman knows, any investor knows, any educated person knows, that doesn't work. For example, an amoeba dividing at its maximum rate will form a ball larger than the earth in 24 hours.

    True, but at least the fact that population growth has been decelerating is a good sign.
