Pollution of the air

• More poisonous gases in the atmosphere• The worst situation in the biggest cities• Caused by overusing cars• Caused by heavy industry• Some factories emit SO2• SO2 + rainwater = acid rain

Acid rains

• = industry gases joined with water steam• Acid rains pollute the water and the soil• Acid rains kill flowers, trees and even animals• Then trees grow more slowly, they grow old

too quickly and die

BUT?!• A lot of forests are destroyed by the man

because of wood and places for new buildings

• Forests are important for oxygen, food, fuel, shelter and medicines

Pollution of the water

• Caused by chemical factories• They are built on river banks• They release sewage water and industrial

waste to these rivers• A lot of water animals die

Shortage of water

• Some rivers are becoming drier• Caused by global warming and by wasting

water by man• There is less fresh water• Caused by pollution of water in the rivers

Global warming

• Caused by greenhouse effect• Carbon dioxide absorbs heat from the sun• More carbon dioxide = the temperature is

going up• Results : melting of icebergs, increase of sea

level, risk od floods

• Ozone layer protects us against UV radiation• Ozone hole is caused by chlorine• Chlorine is in the atmosphere because of

freons• Freons were used in fridges and sprays• Now it is forbidden

Good deeds• I don´t waste water• I separate a rubbish• I don´t use a car a lot

Bad deeds• Using of chemical cleaning products• Sometimes I waste energy•

To conclusion
