> Prior to the industrial revolution, the natural world was nearly infinitely abundant.

The opposite is true. Central Europe was almost devoid of trees. Food was scarce as arable land bore little fruit without fertiliser.

Society was Malthusian until the Industrial Revolution.

Can we interpret "abundant" in a Darwinian sense e.g. diversity of life? I would think the industrial farming revolution decreased crop variety over time same for animal lineages aside from the rapid increase in mixed poodle breeds.
