Thanks! I guess what Turchin describes is something you can relate to as a biologist. Biological systems tend to grow right, consuming resources until the natural surroundings have been depleted and you get collapse.

I find it interesting looking at the old history and how various civilzations exhaust their resources and later collapse. I wrote about it in this article: Water, Wood, Wool and the Materials that built civiilzations: https://medium.com/lessons-from-history/water-wood-wool-and-the-materials-that-built-civilization-ec2e2ff87e9c

It is not quite the same argument as Turchin as he focuses on cycles for a single country, while I was more interested in how once society collapse from resource overutilization and then pass on the baton to the next civilization. Some more years pass and that civilization has exhausted its resources and collapse. This way you end up seeing a constant shift in who is at the top of the civilizatioin pyramid.

What I focused on was forests and soil erosion, but we humans have of course been good at exhausting plenty of other resources.
