Краткое содержание работы
The Earth is the only planet in the solar system where there is
life. If you look down at the Earth from a plane you will see how wonderful our
planet is. You will see blue seas and oceans, rivers and lakes, high
snow-capped mountains, green forests and fields. For centuries man lived in
harmony with nature until industrialization brought human society into conflict
with the natural environment. Today, the contradictions between man and nature
have acquired a dramatic character. With the development of civilization man’s
interference in nature has increased. Every year the world’s industry pollutes
the atmosphere with millions of tons of dust and other harmful substances. The
seas and rivers are poisoned with industrial waste, chemical and sewage
discharge. People who live in big cities are badly affected by harmful
discharge from plants and city transport and by the increasing noise level
which is as bad for human health as lack of fresh air and clean water.
Among the most urgent problems are the ozone layer, acid rains,
global warming, toxic pollution of atmosphere, disappearance of forests,
contamination of underground waters by chemical elements, destruction of soil
in some areas, threat to some flora and fauna representatives, etc.
One of the most important pollution problems is the oceans. Many
ships sail in the ocean water- fishing ships, some ships carrying people, some
carrying oil. If a ship loses some of the oil in the water, or waste from the
ships in put into the ocean, the water becomes dirty. Many sea birds die
because of the polluted water. Many fish are dying in the sea, others are
getting contaminated. Fishermen catch contaminated fish which may be sold in
markets, and people may get sick from eating them. Lakes and rivers are
becoming polluted, too. Some beaches are dangerous for swimming.
Another important problem is air pollution. Cars and factories
pollute the air we use. Their fume also destroys the ozone layer which protects
the Earth from the dangerous light of the Sun. Aerosols create large “holes” in
the ozone layer round the Earth. Burning coal and oil leads to global warming
which may bring about a change in the world’s climate.
The other problem is that our forests are dying from acid rains.
Deforestation, especially destruction of tropical forests, affects the balance
of nature in many ways. It kills animals, changes the climate and ecosystem in
A person can do some damage to the environment but the greater part
of pollution certainly comes from industry. Modern industry production is the
main threat to nature.
There are a lot of places on our planet that need immediate help.
Our country is not exception. The nuclear accident at Chernobyl, which took
place on April 26, 1986., has seriously aggravated the ecological situation in
Belarus. That catastrophe can be considered as the largest disaster of the 20th
century. As the result of that accident 18% of territories of our republic were
contaminated by radioactive elements. The agriculture of our country suffered
great losses. More than 20% of the population has also suffered. A death rate
among children has increased considerably. The wide researches are carried out,
but health state of the people living in polluted areas, is worsened. The level
of thyroid gland cancer has increased, the immunity of children and women is
weakened, many diseases appear out only a few years later. Everyone understands
that this catastrophe is a threat to health of our nation, and though years
have already passed, the results will be shown on the future generations.
I’d like to say a few words about animals in danger of extinction.
The blue whale is the largest animal which has ever lived. Once there were over
200000 of these creatures living in the Atlantic and Pacific oceans. Since the
seventeenth century they......
