The development and impact of children's concern for the environment is addressed. A model is presented that illustrates that such development may be based upon children's cognitive status, their exposure to nature, and their exposure to particular socializing influences. One of the possible outcomes of children's concern for the environment is that they may become catalysts for family environmental consumerism, and thereby influence related family attitudes and decision-making. We propose that environmental consumerism may be moderated by the nature of family communication patterns, which can affect the possibility of family resocialization regarding environmental concerns. In addition, family resources are also expected to moderate the degree of family environmental consumerism. We suggest that environmental consumerism will be reflected in both purchasing and recycling choices and behavior. Consequently, marketing implications are also addressed. © 1995 John Wiley & Sons, Inc.
