Though the issue is a bit more specific than just industrial farming in this case. Meat, dairy, etc. production is inherently really inefficient compared to eating plants because you have to do so much more farming for animal feed where most of the energy is lost

we show that plant-based replacements for each of the major animal categories in the United States (beef, pork, dairy, poultry, and eggs) can produce twofold to 20-fold more nutritionally similar food per unit cropland. Replacing all animal-based items with plant-based replacement diets can add enough food to feed 350 million additional people, more than the expected benefits of eliminating all supply chain food loss.
