that is just how the world works because thats how we MAKE IT WORK. deers wouldn't be considered too many deers if they had more land, the land we took away from them.and war is not necessary to decrease the human population.war is about money ,corupt government,and hatred as a means of resolution.its not some sort of tool for economic equilibrium.there are many ways to decrease population, or provide for them.its more economically reasonable to be vegetarian that to eat meat!the acreage it takes to feed cows could be used to grow soy products , thus cutting out the "middle man" and feeding more people w/ less land.which, is better for the environment!
