40% of all bioavailable nitrogen produced on this planet is produced industrially. Most human beings exist only due to industrialization, they would not exist if industrialization wasn't a reality. Feeding people and having people cannot be separated. You can't have an earth with this many people without industrialization, short of razing all forest land and farming on it, which seems to me to be much more destructive than industrialization.

Industrialization is done in support of human populations. As populations get bigger more and more space must be industrialized.

Your existence (eating, drinking, living) requires X acres of farmland, Y acres of ocean, Z acres of landfill, N tonnes/watts of energy, etc etc etc. No matter how "ethical" you eat or how much housing density you can tolerate, the resources much be spent or you will die.

I suppose it is true that we could all stand shoulder to shoulder connected to IV drips like some kind of sci-fi nightmare (https://en.wikipedia.org/wiki/The_Mark_of_Gideon) but I view this as a bad outcome.
