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.
