Poet, professor and commentator on science for the B. B. C., Robert Brittain is well qualified for the writing of a book about the world's land and hunger problems, a task which he performs admirably. Beginning with a historical survey of population theories and land uses, he points to the fallacy in Malthus' regard for man as a consumer and not a producer and to the vast and very usable resources both in land and knowledge that we now have-the while urging a sensible outlook on birth control and international trade. His following chapters outline the world's frontiers- the Arctic, the tropics, the sea, and methods for their development. From this, Brittain proceeds to a consideration of policies for improvement in presently tilled areas and like Mr. Stamp in Land for Tomorrow, asks for an increase of produce in Canada, the U. S. and Argentina. In this very readable study, the author's vivid language and use of meaningful examples make this a pleasurable and valuable addition to international understanding.
