What causes an earthquake? When will another big shock shake Tokyo or Los Angeles? Can people create deserts? How are the ozone layer and greenhouse effect interlinked? Is global warming a force of Nature - or of man? This revised edition of Andrew Robinson’s compelling and informative book, illustrated with marvellous photographs and specially commissioned artwork, draws on the dramatic evidence of recent years to evaluate the state of the planet in the new century - and man’s effect on it. Each force of Nature is separately described, dissected and fitted into the jigsaw puzzle of global environmental change.
