Environmental problems

  • People have always polluted their surroundings.
    But until now pollution was not such a serious
    problem. People lived in uncrowded rural areas
    and did not have pollution causing machines.
    With the development of crowded industrial
    cities, the which put huge amounts of pollutants
    into small areas, the problems has become more
    important. Automobiles and other new inventions
    make pollution steady worse. Since the late
    1960s people have become alarmed with the danger
    of pollution.

  • Air, water, and soil are necessary for existence
    of all living things. But pollution air can cause
    illness, and even death. Pollution water kills
    fish and other marine life. On polluted soil,
    food can not be grown. In addition environmental
    pollution spoils the naturals beauty of our
    planet.

4
  • Pollution is as complicated as serious problem.
    Automobiles are polluting the air but they
    provide jobs for people and produce necessary
    goods. Fertilizers and pesticides are important
    for growing crops but they can ruin soil.

5
  • Thus, people would have to stop using many useful
    things if they wanted to end pollution
    immediately. Most people do not want that of
    course. But pollution can be reduced gradually.
    Scientists and engineers can find the ways to
    reduce pollution from automobiles and factories.
    Government can pass laws that would make measures
    for reducing of pollution. Individuals and groups
    of people can work together to persuade
    enterprises to stop polluting activities.

6
  • Large cities with thousand smoky idustrial the
    enterprises appear all over the world today.The
    by-products of their activity pollute the air we
    breathe, water we drink, t0heland, the land we
    grow grain and vegetables on.

7
Every world industry pollutes the ahmosphere with
about 1000 million tons of dust and other
harmful substanses. Many cities suffer from smog.
Vast forests are cut and burn in fire. Their
dissappearance upsests the oxygn balance. As a
result some rare spesies of animals, birds, fish
and plantsdissapear forever, a number of rivers
and lakes dry up.
8
The pollution of air and the world oceans,
destruktion of the ozon layer is the result of
mans careless instraction with nature, a sign of
the ecological crises.
9
The most horrible ecologian disaster berell
Ukrain and its people after the Chernobyl tragedy
in April 1986. About 18 persent of the territory
of Byelarus were also polluted with radioctive
subctances. A great damage has been done to the
agriculture, forests and peoples health. The
consequences of this explosion at the atomic
power-station are tragic for the Ukrainian,
Byelarussian 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.

12
  • Some progress has been already made in this
    direction. As many as 159 countries- members of
    the UNO- have set up environmental protection
    agencies. Numerouse conferences have been held by
    these agencies to discuss problems facing
    ecologically poor regions including the Aral Sea,
    the South Urals, Kuzbass, Donbass, Semi palatinsk
    and Chernobl. An international environmental
    research has been set up on Lake Baikal. The
    international organisation Greenpeace is also
    doing much to preserve the environment.

13
  • But these are only the initial steps and they
    must be carried onward to protect nature, to save
    live on the planet not only for the sake of the
    present but also for the future generations.
