Uczniowie przygotowują rozwinięcie poszczególnych tematów.
1. Discuss the greatest environmental problems in Poland.
2. What are the consequences of air pollution?
- contamination of rivers, lakes and the sea
- the water is viwed as a dumping place and is unfit bathing or drinking
- people living by a river or the sea are more likely to develop various
sicknesses
and skin infections
- destruction of the wildlife habitat
- extinction or decimation of numerous species
- pollution of the atmosphere
- health crisis in Poland - one of the lowest life - expectancy rates in Europe.
- The inhabitants of the most polluted Polish cities are susceptible to medical
problems as respiratory illnesses, infectious diseases, anaemia, developmental
disturbances, miscarriages, mental retardation, congenital diseases.
| Problems |
The source of pollution |
The result |
How can we stop it? Solution |
| ACID RAIN |
Carbon dioxide, clouds of suphur /sulphur
compounds/ in industrial pollution from burning coal and exhaust fumes
produced by cars, which are dissolved in rain |
- polluted water, ruined crops, vegetables in
cities are poisoned /especially lettuce, radish, onion absorb heavy metals/;
ruined fauna and buildings /Mariacki church is becoming black/ frequent
births of retarded children |
- use pure fuel; base the energetics based not
on coal but on alternative sources, for example wind |
| DEFORESTATION |
Ruined trees by acid rains. Cut out forests for
timber or for new cultivated areas-uncontrolled exploitation |
dehydration and soil erosion; fertile regions
will be turned into deserts; the violation of the ecological balance; |
Cutting out forests should be under control;
planing new cultivations and afforestations - green areas assimilate carbon
dioxide |
| GREENHOUSE EFFECT |
ozone hole - the depletion of ozone layer in
the atmosphere. The ozone film protects the biosphere against deadly
ultra-violet radiation of Sun. The ozone is a filter-it absorbs the
ultra-violet part of radiation 95% we own our tan to the rest 5%;
radioactive beans are getting into our atmosphere |
- the world's climate is warming up carbon
dioxide absorbs warmth; the melting of huge icebergs; The natural division
between seasons may be disturbed; displacement of zones to the north cancer
of skin /especially white population is subject to this illness/ |
The production of freons should be stopped. They
are applied in refrigerators, sprays and skating-rinks Space expeditions
should be stopped. |
| ENVIRONMENTAL TREAT |
devastation of forests; incautious fertilising
in agriculture; trade of exotic animals |
Animals lose their seats. The extinction of
species; ideal conditions for the development of noxies insects and bacteria.
Interruption of an alimentary chain. There are less plants to obtain drugs. |
Strict regulations concerning the trade of
animals and their products nature reserves, wildlife habitat. |
| NUCLEAR CONTAMINATIONS |
Testing and storage of nuclear weapon.
Contamination with nuclear fuel. Transport and storage of nuclear waste.
Disasters. |
Contamination of seas and annihilation of life
in them. Plants and animals diseases, threat of human life and
health-diseases caused by radiation |
Cessation of experiments with nuclear weapon |
| WASTE OF RESOURCES |
Utilisation of natural resources, not taking
into consideration they are unregeneratable. Waste |
Danger of the total exhaustion of resources.
Lower level of life in the future |
Emphasis on creating strong things and repairing
them, not throwing away. Economical management of resources. |
3. Podsumowanie wypowiedzi i wyciagnięcie wniosków - w jaki sposób możemy
przyczynić się do złagodzenia skutków powyższych procesów.
