The problem of peace is considered to be ecological. Ecology is the study of the complex interrelationships between organisms and their environments. To clarify this approach, three major types of social complexity--organizational, problem, and conceptual--are briefly reviewed together with their interactions and their effect on the individual. A practical approach to handling, generating, and facilitating comprehension of this complexity by the use of interactive computer graphics is then described in terms of its significance for a variety of users. The paper does not suggest a new theoretical model to examine the problems of peace, but rather shows the relevance of an existing device to many such inquiries. In demonstrating this relevance, peace is treated as an ecological problem because of the high tolerance of the ecological approach to complexity of the order detected in the psycho-social system. The closing sections comment on the relevance of this approach to value and knowledge requirements for peace and suggest some practical steps which could be taken. (Author)
