How will environmental changes such as ozone depletion and global warming affect human health? Tony McMichael, an epidemiologist, argues in Planetary Overload (Canto, 拢7.95 pbk, ISBN 0 521 55871 9) that 鈥渢he erosion of the Earth鈥檚 life-support systems鈥� is not a problem of minority interest, but that it poses real health hazards which will affect the lives of everyone on Earth. Ignore McMichael at your peril.
