A lot of people don't talk about this or acknowledge it, but majority of the earth's topsoil will be depleted by or around 2040, a fuckton of people are going to starve to death within our lifetime regardless. Doesn't matter if its meat or plants - there's just too many fucking people at the end of the day, and people are going to get culled for it.

Quite correct.
Phosphorus is important for plant growth and its defficiency is one of limiting factors for crop yields.
As it turns out about 70% of phosphates used in fertilizers is immediately immobilized in soil in natural chemical reactions and isn't bioavailable - plants can't use them.
So in fact most soils are already oversaturated with phosphates but plants can't access them, meaning we still have to fertilize.
Now, fun part: easily available phosphates (I believe mostly apatites) that can be mined are depleting fast. It was said that during our lifetime we will use up all of them and we will have to switch to phosphates mined from the bottom of ocean floor. You can imagine how expensive it is so prices of everything based on fertilizers will skyrockets. Both meat and plants.
