Originally published in Britain and with more attention than we would give to British problems and solutions though the overall concern is worldwide, this is an unremarkable reiteration of manmade damage to date and of current conservationist measures. There are lists of animal casualties and examples of the balance of nature, enumeration of types of threats and dangers to wild animals, and a haphazard survey of a few national parks, zoos, breeding and translocation projects and wild animal ranches. Though Jenkins concludes that ""if we destroy nature we shall destory ourselves,"" an early chapter on ""why conservation"" gives only the less urgent reasons -- responsibility toward lesser creatures, man's need to appreciate the beauty and wonder of creation, the consideration of scientific knowledge, and the animals' economic value as tourist attractions! And though he points out that each stage up in the food chain involves a ten-to-one reduction (so that for a human to gain one pound from eating fish nearly half a ton of vegetable plankton is required) all he makes of this is that no one animal can be studied in isolation and ""habitat must be the basis of any proper study of nature.""
