Топик: Environmental problems
The poisoning of the world's land, air, and water is the
fastest-spreading disease of civilization. It probably produces fewer headlines
than wars, earthquakes and floods, but it is potentially one of history's
greatest dangers to human life on earth. If present trends continue for the
next several decades, our planet will become uninhabitable.
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 population is a very serious problem. In Cairo just breathing
the air is life threatening- equivalent to smoking two packs of cigarettes/ a
day. The same holds true for Mexico City and 600 cities of the former Soviet
Union.
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.
