The number of people seeking refuge as a result of environmental disaster is set to increase dramatically over the coming years. Ironically, given current attitudes, industrialised countries will resist accommodating them, and yet they will have become refugees as a direct result of the way the west lives. Global warming - more than war or political upheaval - stands to displace millions. And climate change is being driven by fossil fuel-intensive lifestyles. Though they have no official status, environmental refugees are already with us.
