Environment of Man is the eighth of the Croom Helm series of mono­ graphs on Biology and the Environment. The first volume, by this author, was a straightforward review of the principles of ecology as applied to the history of the earth. The second volume by J.L. Cloudesley-Thompson applied ecological principles to terrestrial habitats, and was followed by two volumes by C. F. Hickling and E. J. Ferguson-Wood on the ecology of aquatic habitats. The fifth volume, by Robert L. Snyder, reviews the natural ecological safeguards which control excessive growth of popUlation and discusses how these are operative in relation to the human race. Snyder's volume introduces man to the ecological scene and leads to the monograph by L. Harrison Matthews on the relationships of man with wildlife. In the seventh volume, Sir Cedric Stanton Hicks introduces us to the effects of agriculture on the ecology of the earth.
