Review : Gasping for air

We are slowly suffocating ourselves, explains Derek Elsom in
Smog Alert
(Earthscan, £14.95, ISBN 1 85383 192 1). Why is it happening?
Who will
expire first? Progress towards clean air in the 21st century may be hampered by
setbacks from individual pollutants, but Elsom argues that the ultimate goal of
a breath of fresh air for everyone must be borne in mind throughout what will
inevitably be a costly and difficult struggle.
