POLLUTION SOUND AIR WATER SOIL Caused by an eccessive esposition to sound and noises Caused by fertilizers and pesticides Caused by the introduction of toxic substances in the air Caused by the emission of substances which can change the water caracteristcs It provokes changes in the biological and physical balance of the soil It provokes both the ozone hole and the greenhouse effects It provokes stress and sleeping problems It provokes eutrophication
FACTORY Water pollution
Chemical Steam and smoke- Air pollution
Solid Waste Pollution
ATMOSPHERE IN DANGER !
QUANTITY OF co2 EMITTED IN ATMOSPHERE 24 billion of tons a year
Effects of Air Pollution Health problems Damage to the environment Thinning of the protective ozone layer of the atmosphere which is leading to climate changes
Greenhouse Effect Another serious danger that threatens the planet is the greenhouse effect, caused by the enormous amount of carbon dioxide and other greenhouse gases poured into the atmosphere. The increase of these gases due to the burning of fossil fuels and forest fires, is causing excessive heating of the planet. The consequences are devastating: the melting of ice at the poles, rising sea levels, an increase in desert areas and the drying up of farmlands.
Ozone hole The environment is subjected to severe hazards due to pollution. One of them is due to the placing of chlorofluorocarbons into the atmosphere, the gases contained in refrigerators and in aerosol spray cans. These gases had decreased the thickness of the ozone layer and, at the polar regions, caused even holes in it.
