Issue Date: Nov 30, 1992 The cold war between the superpowers
not only left the entire world cold in fear, but perhaps also
cooled the Earth, say Russian researchers K Y Kondratyev and G A
Nikolsky. Their theory is that the atmospheric nuclear tests of
the early 1960s released into the stratosphere vast amounts of
nitrogen oxides, which combined with sunlight, expedited ozone
depletion. The oxides triggered off ozone-destroying reactions,
thus using up a part of the sunlight that would otherwise cross
the stratosphere and warm the surface of the Earth. Cheryl
Colopy‘s book explores how south Asian rivers have been
transformed from being considered sacred beings to sewers How a
township has set high standard for eco-friendly living
