TO THE LAST DROP: CANADA AND THE WORLD'S WATER CRISIS. Keating, Michael. Toronto, Macmillan, c1986. 265pp, cloth, $26.95, ISBN 0-7715-9704-5. CIP Grades 10 and up Reviewed by Graham A. Draper Volume 15 Number 2 1987 March It is a paradox. Canada has one-seventh of the world's fresh water and yet we are fast approaching a time when we will have a shortage of safe, clean water. On every side we seem intent on destroying this natural resource through carelessness or outright disregard for the environment. The discouraging part is that the pattern shows no sign of changing. We continue to speed toward a national and global water crisis. Keating has explored the question of diminishing water resources in great detail. An award-winning environmental writer for The Globe and Mail, he brings to this study a thorough knowledge of his topic, plus the ability to write in a way non-specialists will appreciate. Early chapters in To the Last Drop examine the nature of the pollution that affects our water and the extent to which Canadian sources have been damaged. The central part of the book focuses on specific aspects, such as pollution of the Great Lakes, acid rain, the effects of climate change, water diversion schemes, and ownership questions. Keating brings his study to a close by looking at what has been done to deal with the problem, and what remains to be done. His conclusion: we must act quickly or face serious consequences. To The Last Drop has a great deal to offer to students. The author has provided background information hut has kept the book accessible for students by avoiding a strong scientific focus. The broad topic coverage will make the book useful in many situations. Appendices offer up-to-date statistics and sources for more information. In short, the book will make a valuable addition to a collection. Recommended. Graham A.Draper, Longstaff S.S., Richmond Hill, Ont.
