It’s pretty niche. The place I go started a program to help breed pigs back down to a reasonable size. Apparently they have painful problems from being over bred, like hip dysplasia. They are networking with other small farms to breed their pigs progressively smaller and healthier.
But yeah, not really putting a dent in the factory farming problem and not accessible to most.
