How much living space does a person need? What happens when his space requirements are not adequately met? Sociologists and psychologists are conducting experiments on rats to try to determine the effect of overcrowded conditions on man. Recent studies have shown that the behavior  If rats have adequate living space, they eat well, sleep well, ant reproduce well. However, if their living conditions become too crowded, their behavior patterns an even their health perceptibly change. They cannot sleep or eat well, and signs of fear and tension become obvious. The more crowded they are, the more they tend to bite each other and even kill

each other. Thus for rats, population and violence are directly related. Is this a natural law for human society as well? Is adequate space not only desirable, but also essential for human survival?
