We are slowly suffocating ourselves, explains Derek Elsom in
Smog Alert
(Earthscan, £14.95, ISBN 1 85383 192 1). Why is it happening?

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.
