The key word you used is "intensive". Livestock are animals in too, and we can use techniques to harvest animal products while maintaining a balance in the ecosystem. You can see this in grazing management to turn desert back into grasslands in Africa. And instead of spraying insecticide that runs off and kills things downstream, we can pasture chickens in the same fields we grow crops and they'll happily turn those insects into eggs and meat. Intensive agriculture is fighting nature. We can work with nature instead for both crops and animal products and still get great yield.
