Thankfully, others are more optimistic and are addressing these problems. A wonderful new book rehearses this solution in some detail. Seven of the regions are in Asia and the East Indies, five each in Africa and South America, three in Australia and New Zealand, one in the Mediterranean, one in Central America and one encompasses all of Polynesia. Only two regions overlap with the United States. They are also lands stressed by terrific pressures.
Identification is, of course, only a necessary first step in addressing the problems of our planet.
Among the beautiful pictures of threatened exotics in this book are compelling shots of human devastation.
