Half the habitable land is farm land and farm land is ecologically dead (with pesticide use having damaging effects on the surroundings) and not available for carbon sequestration for instance.
Also "livestock accounts for 77% of global farming land. While livestock takes up most of the world’s agricultural land it only produces 18% of the world’s calories and 37% of total protein"
Even 100% efficient agriculture is meaningless in the face of overburdening absolute demand.
Raising efficiency and means of exploitation may also induce demand ("oh we're so eco-friendly").
The point is: Life needs (contiguous) undisturbed wilderness.
And ecological management?
That this would even be necessary is testament to our fuckup, but yeah that might actually be topic's biggest benefit I suppose.
Pre-industrialisation life managed itself just fine for millenia.

What do you mean by that, specifically? Clearly we benefit enormously from what has happened since, including food, shelter, peace, freedom, knowledge, etc. etc. I just got something called a vaccine, which protects me from a deadly disease. Someone stuck a needle in my arm, but they had figured out how to do that perfectly safely. The vaccine was driven to the provider, kept cold in refrigeration, and I also drove the provider after making prior arrangements via telecommunications. You're literate and reading this on a website using a computer, a vast collection of manufactured items ... You get the idea.
Regulate the supply side with land use restrictions and restoration of natural habitat; introduce subsidies for underdeveloped and emerging economies to prevent further ecosystem degradation out of economic necessity.
With a set limit on land use, market prices would adjust accordingly (i.e. meat price rises), consumption will reduce (accompanied by some whining) and food innovators get more time and market share for sustainable alternatives.

And the trend is growth..
