Ugh, I accidentally deleted my previous comment when trying to edit, sorry for the double reply.
Original reply:
You think that the amount of land being dedicated to making food for livestock dwarfing the amount of land dedicated to feeding people is not a legitimate complaint?
Edit: eyeballing it, we use twice as much land (and as a result, water, energy, etc used in the farming process) making food for livestock (ie, food for what will become food) as we do making food for us
