The document discusses various threats to the environment and ways to protect nature. It notes that industrialization has led to greater contradictions between humans and the environment. Issues like pollution, overpopulation in cities, and waste are damaging the environment. Litter and improper waste disposal harm health and spoil natural areas. Factories release dangerous chemicals into the air, water and soil. Unless immediate action is taken to reduce pollution and clean up contaminated sites, more environmental damage and species loss will occur. Everyone must work to maintain clean land, air and water for future generations.

About two hundred years ago man lived in
greater harmony with his environment
because industry was not much developed.
Today the situation is quit different, the
contradictions between man and nature are
dramatic.
3. • People all over the world are worried about
what is happening to the environment.
Newspapers, magazines write about water
pollution, air pollution, and land pollution.
Now many parts of the world are crowded,
people live in big cities. Where many people
live together, litter is a problem. People don't
always put garbage into the garbage can.
4. • It's easier to drop a paper than to find a garbage
can for it. But litter is ugly. It makes the city look
dirty and spoils the view.
• Litter is a health problem too. Food, garbage
bring animals, which sometimes carry disease.
• Much of our waste, waste from factories, the
chemical industry, heavy industry are very
dangerous. Fish dies in the lakes, rivers, seas;
forest trees die too. Much of this dangerous
waste goes into the air and is carried by winds for
great distances.
5. • People don't get enough oxygen in big cities.
They suffer from smog. You can hardly breathe
the air any more in our cities. And think of
noise. Nowadays most city centres are simply
too noisy to live in. We've got to live with a
motor car but we've got to become its master
and not its slave.
6. • he Earth is our home. We must take care of it for
ourselves and for the next generations. This
means keeping our environment clean. The
importance of this task is pointed out by
ecologists, the scientists who want to control this
problem. Each of us must do everything possible
to keep the land, air, water clean. More than 30
years ago the Aral was a bright sea with a lot of
fish. The rivers Amudarya and- Syrdarya supplied
it with water. But then the water of the rivers was
diverted to cotton plantations. As a result, the
Aral now is in a very dangerous position.
7. • If no immediate measures are taken, the Aral
Sea will disappear by the year 2010.
• There are many other places in our planet that
need immediate help. For example Lake Baikal
and its shores have been declared a specially
protected zone of our country. There is a hope
that one of the most beautiful and the
deepest lakes of the world will never die.

8. • Our planet is in trouble! Almost every day we
seem to hear of yet another problem affecting
the environment - and what a list of problems!
- pollution, acid rain, climate change, the
destruction of rainforests and other wild
habitats, the decline and extinction of
thousands of species of animals and
plants....and so on.
9. • Nowadays, most of us know that these threats
exist and that humans have caused them.
Many of us are very worried about the future
of our planet and unless we can find a way of
solving the problems we have made then the
environment will suffer even more.
