This book distils what is known about global warming, pollution, population pressure, resource use, extinction, etc., with examples from Australia and all over the world. It is clear, concise and forceful. Having set out the problems, John Nicholson also takes care to include lists of actions being taken, suggestions for things governments and industry should do, and things ordinary people can do in their everyday lives, as well as some inspirational good news stories (eg primary school children buying rainforest in Ecuador).
