An urge toward territoriality occurs in all thinking animals and in some that don’t think. The need for a constant and reliable source of food explains some of the perceived necessity behind this pattern of behavior. However there are times when food is plentiful and you’ll still see folks of all species vigorously defending their own patch of earth. It is also certain that the reproductive urge plays a part in the defense of territory large and small. But neither food or sex is the end-all and be-all to explain species-wide defense of territory. There is a part of the brain that is devoted to want and getting mad when you can’t have what you want that could be the precursor to territoriality. It is a complex association of areas in the brain that begins working from birth. This complex of sections of the brain can drive a need for possession, for something that is mine, all mine and no one else can have it, even if it means fighting to the death. For some reason many individuals want, then need to have more than others of their species, to have more possessions and to be sure that they are all accounted for at all times. They can be quite vocal and violent about what they consider are their rights. But all the conflicts surrounding territoriality are ridiculous, especially since none of the things being disputed will be available to anyone for very long into the future. There seems to be a belief among this type of being that what’s mine is mine, and what’s yours is mine, too. It’s a shame that so many of us don’t so can’t begin to counteract this behavior, at least in humans and the ‘domesticated’ animals, from the very beginnings of it in infancy. There isn’t anything we can ethically do about territoriality in other animals, but we can try to do something about destructive territoriality in our own species by attempting to nip the urge in the bud or providing a strong, but flexible example of sharing. Would you try to express sharing, by example or other peaceful means?
