The quality of the environment in which people live, work, and play influences to no small degree the quality of life itself. The environment can be satisfying and attractive and provide scope for individual development or it can be poisonous, irritating and stunting. The papers in this volume, first published in 1969, are concerned with the urban environment – in which the majority of Americans live – or, more accurately, with the environment of urbanites, for the concern extends to outlying areas where urban dwellers visit and play. The chapters aim to provide a better understanding of the natural resource elements in the urban environment, and will be of interest to students of environmental studies and human geography.
