For the first time in the history of the world one species has grown so numerous and so technologically powerful that it has the ability to destabilize the narrow range of temperature within which life can flourish. And we are now doing just that. Our generation is the guilty generation, but we will only just begin to feel the consequences of our actions, it is our children's and grandchildren's generations that will suffer. This book is a call to arms. We have time still to halt and reverse the process. Maybe 10 years, maybe less - we have to throw our engines into reverse now in the battle to control our carbon emissions. Each one of us, acting collectively, can make a very real difference to the future of the world we live in. And we can do it very simply and easily. Bill McGuire tells us how.
