The dangers of environmental change for people and what they value is what makes environmental issues so important for our future. This volume presents a comprehensive analysis of environmental risks. Contributors assess the identification and causes of risks, who and what is vulnerable to them, their regional distribution and the policies and measures for mitigating them. The editors provide an extensive introduction to the issues and introductions to each part, showing that while global risk futures may be unavoidable, they are still amenable to risk analysis and carefully designed policies for amelioration.
