Environmental problems
Environmental problems are of a great concern nowadays. More and more
scientists warn about the threat of a global ecological catastrophe as a
result of man’s economic activity. Medics note with alarm the growing
number of diseases caused by air and water pollution.
The ecological situation is particularly unfavorable in large cities. In
London, for example, the dust concentration (daily average) in air
exceeds the permissible level by 60 per cent, in Paris – 80 %. The
situation in Moscow is even worse in some aspects. The carried out
research showed that up to 12 million tons of harmful substances are
discharged into air annually. Hundreds of industrial enterprises pollute
atmosphere.
Ecological problems are also very acute in Arkhangelsk region and in our
city. The ecological situation in the region is influenced by a powerful
industrial military complex, which includes the defense enterprises in
Severodvinsk, cosmodrome in Plesetsk, nuclear test site in Novaya
Zemlya. Out of 20 cosmodromes in the world one of them is in Plesetsk.
City’s population are also worried about the Northern Dvina. Sawmills
and pulp and paper plants contaminate water. As a result the ecological
balance in the river upsets.
Transport is a major source of environmental pollution. Every car
exhausts tons of CO2 into the air.
Another source of public concern is disappearance of forests. Their
disappearance upsets the oxygen balance. Among other acute ecological
problems are: pollution of the world’s ocean, radioactivity, noise and
other types of pollution, destruction of ozon layer, deserts’ advance,
green-house effect, acid rains, etc. They are result of men’s careless
interaction with nature.
