Basically, low quality food is flooding the market, and getting purchased by the poorer population, that don't feel they have a choice in what they eat, because they eat whatever is necessary to fit in their budget.
Meanwhile people that CAN afford to buy high quality food from family farms, don't, because of activism convincing them that doing so is evil, specially any farm that has anything to do with animals, this results in things that are actually really bad, like climates where wool is an excellent product have the farmers fail due to lack of demand, and instead people start buying plastic-based clothes, that contribute to plastic pollution.
Or in Brazil: people love to blame the animal industry there for the fires, but it is not so simple, the massive areas being deforested ilegally are often used to produce soybeans, that are on an evergrowing demand due to two sources of demand compounding:
1. As family farms die, cattle instead of eating grass (something that in Brazil and some other countries was important, as some places only grow grass, and not other plants more useful for direct human comsumption), people switch to factory animal farms, that require rations, that are often made of soybeans.
2. Meanwhile the upper strata of society is switching from high quality meat (that would eat grass) to eating soybean-based products (like soybean milk, soybean-based meat, etc...)
I think many activists have their heart in the right place, but they don't understand they are causing more problems than fixing them, the soybean industry is massively destructive, incentivizing it is extremely bad idea.
final note: Remembered other major source of soybean usage... when in the 60s and 70s there was this massive media campaign against usage of animal fats for frying, people switched to soybean oil to fry instead, Brazil also produces massive amounts of that, and I know many people that personally use soybean oil because they honestly believe it is healthier to them and better for the environment than using butter, pork fat, etc...
