That's definitely true. Factory farming is definitely an issue, and in more ways than one. My point is that we need grazing cattle too, since we (as a species) took the liberty of wiping out most of the naturally occurring grazers and thereby wrecked the balance. The "easy" way would be to limit the spread of humanity in order to reduce the load on the ecosystem, but that would result in numerous demographic issues instead. Fun times ahead!
