3. The sources of pollution
• The environmental pollution can be
caused by natural sources (e.g.
volcanoes), or be artificial (caused by
the human activity) which is taking
place as a result of the unintentional,
but systematic human activity.
4. Types of pollution - Air
Types of pollution:
A) Air Pollution
The presence of various substances in
the atmosphere in such
concentration and for long period of
time leads to adverse consequences
for the health and well-being of
people and other living things.
5. Types of pollution – water
B) Water pollution.
Those are the changes in
physical, chemical and
biological state of the water
that make usage of the
groundwater for drinking, or
economic purposes
impossible.
6. Types of pollution - noise
C) noise
The problem of noise is
omnipresent these days. The
noise is caused by machinery,
various means of transport
such as planes, cars etc.
7. Types of pollution - Radioactive contamination
D) Radioactive contamination
It is the contamination of the
water, soil or air usually caused
by bad disposal of radioactive
substances, nuclear machinery
failure, or the atomic bomb
explosion etc.
8. Pollution of Landscape & Light
E)Pollution of Landscape
It is reducing the aesthetic value of the
environment by human interference,
f.e. by creating waste dumps.
F)Pollution of Light
It is mainly excessive light emission
which usually interferes the
astronomical observations, and
prevent wild animals from feeding.
9. Ecologists are on strike!
Due to water and air pollution 6 million people die
every year! Ecologists cannot agree with this
situation and are striking. They appeal for "better
treatment of the nature."
The most serious effects of environmental degradation
that have the influence on the organisms living on
Earth are:
- global warming
- The ozone depletion
- smog
- acid rain
- tropospheric ozone
- noise
- odors
10. Crisis in agriculture
In Polish agriculture, the crisis
caused major decrease of the
prices of goods manufactured
and sold in rural areas.
11. The crisis in the industry
Industrial crisis manifested itself
mainly in the form of declining
of the production. The largest
decline occurred in mining
and heavy industry – that is, in
sectors of the economy which
are the country's economic
potential.
12. Government policy towards the crisis
During the crisis, the Polish government has
defended the Polish current - Zloty. The most
important feature of a deflationary policy was to
bring all the elements of economic life to the
principle of maintaining a stable currency and a
fixed exchange rate. In practice, it was based on
the inhibition of growth of money in the circulation,
the introduction of the Polish Bank credit constraints,
reducing funds for investment and cut budgetary
spending.
13. Prevention of pollution
The actions to be taken to prevent pollution of the
environment are:
-Recycling
-Reduction of carbon dioxide, and dust emission
into the atmosphere
-Reducing the production of fossil fuels
-Promoting the usage of renewable energy sources
(solar power, wind turbines)
-Manufacturing the reusable products
