Although technical in its analysis, this book, written by an American professor of botany, Arthur H. Westing, asserts some troubling facts such as that 26 percent of South Vietnam was carpeted with deep bomb craters by B-52s. Dealing with the effects of high explosive munitions, anti-plant chemicals, large-scale land clearings and more, the book has policy implications for current efforts in Geneva to negotiate controls on environmental modification as a means of warfare.
