THE FIRST BOOK OF CONSERVATION

A very competent and brightly written introductory survey outlines the interrelatedness in nature and the actions necessary when the harmony is broken. There is material on the work of insects; animals that do ordinary and ""special"" jobs; the American continent long ago and the ""progress"" that has necessitated extensive conservation programs. What the individual can do is stressed at the last. Compare this with Wilfrid Bronson's Freedom and Plenty (Harcourt, 1953), a more probing book with less stress on the zoological aspects.
