"The media are full of stories about environmental problems and their solutions; political parties attempt to convince us that their policies will address the challenges that face us; and we as individuals face questions about the effect of our lifestyles on the world around us. To engage with these complex issues - as consumers, voters and citizens - we need to be able to understand what lies behind the news stories and political arguments. The aim of this short book is to give you the tools you need to identify the important questions, assess the evidence and draw your own conclusions."--BOOK JACKET.
