Climate change, urban congestion, nuclear waste, destruction of wildlife - how can we respond to these and the many other environmental problems that beset us? Can we trust the experts? Are political solutions possible? Should we be optimistic or pessimistic about the future of the environment? This book focuses on how environments respond to human actions and the technical, economic and political responses that we make in the face of environmental changes. It is richly illustrated drawing on examples from across the world.
