DESCRIPTION:The ozone hole in the Antarctic stratosphere is mainly due to\
 nman-made chemicals from the opposite hemisphere\, the industrial\nnorth. 
  It was the first global-scale environmental phenomenon to\nbe understood 
 well enough to be taken seriously by big business\nand governments\, and t
 hus to bring about a new symbiosis between\nregulation and market forces. 
  Understanding the ozone hole was a\nnotable scientific achievement becaus
 e of its immense complexity.\nThere are strong interactions between dispar
 ate timescales\, from\nfemtoseconds as photons hit molecules out to the ma
 ny decades\ngoverned by the fluid dynamics of the Brewer-Dobson circulatio
 n.\nMathematical modelling of such multi-timescale interactions is\nfamili
 ar in physics and chemistry but has often been neglected in\nresearch on b
 iological evolution -- in particular\, in the old\npopulation-genetics mod
 els that led to selfish-gene theory.  Those\nmodels miss many crucial aspe
 cts of\, in particular\, human evolution.
