3. 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

4. FACTORY
Water pollution

5. Chemical
Steam and smoke-
Air pollution

6. Solid Waste Pollution

7. ATMOSPHERE IN DANGER !

8. QUANTITY OF co2 EMITTED IN ATMOSPHERE
24 billion of tons a year

9. 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

10. 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.

11. 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.

12. Ouch! What happened to my home?! Water Pollution
                                                                                                                                       

13. Water Pollution Sources
How
Toxic substances dissolve or deposit in the water.
Toxic substances enter lakes, rivers, streams, etc.
Pollutants go down into the ground.
Sources
City sewage
Industrial waste
Agricultural run-off

14. Effects of Water Pollution
                                                                        
Devastating to people and animals, fish, and birds.
Unsuitable for drinking, recreation, agriculture, and industry.
Destroys water life.

15. The results…

OUCH!!!
WHAT HAPPENED TO MY HOME?!

18. Solid Waste Types of waste Household waste Industrial waste
Biomedical or hospital waste
Why

19. SOLID WASTE POLLUTION

20. OUCH!!! WHAT HAPPENED TO MY HOME ??!!

21. Noise pollution
Noise pollution is caused by frequent exposure to loud noises or sounds. It can cause pressure problems, stress and you can even become partially or completely deaf.

22. WHAT A NOISE !

23. What can we do?

24. WHAT ARE WE GOING TO DO?

25. Air Pollution Solutions Encourage your family to walk more
