...oops. Only just seen your "In short:" ninja edit, so I am now responding to the bits you added...
I agree that moving away from petrochemical fertilisers would be fantastic.
I don't agree that we "
must" acknowledge the green revolution saved a billion from starving. wtf? Absolutely not.
Or that we need to generate "massive surpluses" to avoid starvation. Nope.
At very best, the "green revolution" was a relatively short term "fix" that has had, and is still having, many negative long term consequences that may well lead to many more people starving.
There are more than enough resources on our beautiful abundant earth to adequately feed every single man, woman, boy and girl on the planet.
It is the
uneven distribution of those resources due to our fucked up political and economic systems, (
:cough: capitalism
:cough:) that leaves many going hungry while others can afford to throw food away and have lifestyles that result in more early deaths from mostly preventable "diseases of affluence".
I also do not buy into the notion that there is a requirement to breed billions of land animals into existence in order to feed ourselves and for soil fertility. In my opinion that is wrong on so many levels.
It is massively inefficient, as can be clearly seen on the Our World In Data land use graph that I posted sometime ago on another thread, which I'll repost now...

...based on the FAO data, I calculated that we could supply 100% of our global calorie and protein requirements using 37% of the land we currently use for agricultural purposes...

Even if that 37% figure has over estimated the food production efficiency, there is plenty of wiggle room.
I'm not sure why there is an insistence that animal manure is a required input for growing crops. That ain't necessarily so.
There are people out in the real world managing to do just that, no animal product input! I've seen them with my own eyes.
Of course stock free agriculture is not currently a widespread practice, however with 95%+ of the global population not being vegan, that's hardly surprising.
