  The poisoning of the world's land, air, and water is the fastest -
spreading disease of civilization.
  Overpopulation, pollution and energy consumption have created such planet
wide problems as massive deforestation, ozone depletion, acid rains and the
global warming that is believed to be caused by the greenhouse effect.
  The seas are in danger. They are filled with poison: industrial and
nuclear waste, chemical fertilizers and pesticides. The Mediterranean is
already nearly dead; the North Sea is following. The Aral Sea is on the
brink of extinction. If nothing is done about it, one day nothing will be
able to live in the seas.
  Every ten minutes one kind of animal, plant or insect dies out for ever.
If nothing is done about it, one million species that are alive today will
have become extinct twenty years from now.
  Air pollution is а very serious problem. In Cairo just breathing the air
is life threatening — equivalent to smoking two packs of cigarettes а day.
The same holds true for Mexico City and 600 cities of the former Soviet
  Industrial enterprises emit tons of harmful substances. These emissions
have disastrous consequences for our planet. They are the main reason for
the greenhouse effect and acid rains.
  An even greater environmental threat are nuclear power stations. We all
know how tragic the consequences of the Chernobyl disaster are.
  People are beginning to realize that environmental problems are not
somebody else's. They join and support various international organizations
and green parties. If governments wake up to what is happening — perhaps
we'll be able to avoid the disaster that threatens the natural world and
all of us with it.
