"This book by Officer and Page is largely optimistic. It tells the stories of how a number of key environmental problems here and abroad have been recognized and dealt with, often with success, often at the instigation of single individuals, from visionary U.S. presidents to outraged mothers. Human affairs, after all - both problems and solutions - do not come about of their own accord. On local, regional, national and even international levels, environmental problems in great variety have been successfully addressed by determined people and quite often solved."--BOOK JACKET.
