Considers the natural forces of earthquake, volcano, hurricane, flood, avalanche and drought, and studies the latest research. The book is divided into three sections. First we see how men have perceived their relationship with nature, then how the evolution of the earth has created present conditions, and finally all the forces are combined in a look at global environmental change. Robinson takes the view that understanding how nature and humans interact has never been more urgent. Illustrated with spectacular photographs and specially commissioned artwork.
