«Ecological problems»

Since ancient times Nature
has served Man, being the
source of his life. For
thousands of years people
lived in harmony with
environment and it seemed to
them that natural riches
were unlimited. But with the
development of civilization
man's interference in nature
began to increase.
Large cities with thousands of smoky
industrial enterprises appear all over the
world today.
The by-products of their activity pollute the
air we breathe, the water we drink, the
land we grow grain and vegetables on.
Every year world industry pollutes the
atmosphere with about 1000 million tons of
dust and other harmful substances. Many
cities suffer from smog.
Vast forests are cut and burn in fire. Their
disappearance upsets the oxygen balance.
As a result some rare species of animals,
birds, fish and plants disappear forever, a
number of rivers and lakes dry up.
The most horrible ecological disaster befell Ukraine and its people after the
Chernobyl tragedy in April 1986.
A great damage has been done to the agriculture, forests and people's
health. The consequences of this explosion at the atomic power-station are
tragic for the Ukrainian, Byelorussian and other nations.
Environmental protection is of a universal concern. That is
why serious measures to create a system of ecological
security should be taken.
Some progress has been already made in this direction.
As many as 159 countries — members of the UNO — have
set up environmental protection agencies.
The international organization Greenpeace
is also doing much to preserve the
environment.
But these are only the
initial steps and they
must be carried onward to
protect nature, to save
life on the planet not only
for the sake of the
present but also for the
future generations.
