Biological competition is the antagonistic rivalry in which living beings are engaged in a life and death struggle for a part of the existing means of survival which are insufficient for the minimum needs of all. This situation is inherent in nature and among wild animals incapable of social cooperation. It can exist among men (1) in those rare instances where the means of survival are insufficient for total survival for groups which are lost or otherwise isolated from civilization, or (2) where men fail to realize that the voluntary social cooperation of an unhampered market economy can increase the supply of scarce goods beyond the quantity needed for the general survival of a growing but intelligently limited population.
