2 is the introduction by man into the environment of contaminants that contain harmful substances.

3 There are different types of pollution: Air pollution Air pollution Water pollution Water pollution Noise pollution Noise pollution Waste pollution Waste pollution Radioactive contamination Radioactive contamination

4 Air pollution is the human introduction into the atmosphere of chemicals, biological materials that cause harm to humans or other living organisms, or damages the environment. is the human introduction into the atmosphere of chemicals, biological materials that cause harm to humans or other living organisms, or damages the environment.

5 Air pollution leads to such harmful results as: Greenhouse effect Greenhouse effect Acid rains Acid rains Depletion of the ozone layer Depletion of the ozone layer

6 Greenhouse effect is caused by harmful gases known as greenhouse gases. These gases are produced when we burn fuels. These gases go up into the Earths atmosphere and stop heat from leaving the Earth. is caused by harmful gases known as greenhouse gases. These gases are produced when we burn fuels. These gases go up into the Earths atmosphere and stop heat from leaving the Earth.

7 As the heat cant escape, the temperature on the Earth is running up. This is known as global warming. Global warming may result in the melting of the ice at the Poles and rising of sea levels, leading to serious flooding and other disasters in many parts of the world.

8 Destruction of the ozone layer Ozone is a gas that forms a layer in the upper atmosphere and it protects us from ultraviolet light coming from the sun. Ozone is a gas that forms a layer in the upper atmosphere and it protects us from ultraviolet light coming from the sun. It is being damaged by chemicals which are used in refrigerators and in some aerosols, and when holes appear in the ozone layer, harmful light from the sun reaches the Earth.

9 Acid rain Acid rain is rain that is harmful to the environment because it contains acid from factory smoke. is rain that is harmful to the environment because it contains acid from factory smoke. It causes damage to trees, rivers and buildings.

10 Water pollution Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants which live in these water bodies. is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants which live in these water bodies.

11 Oil spill is the release of a liquid petroleum into the environment due to human activity, and is a form of pollution. is the release of a liquid petroleum into the environment due to human activity, and is a form of pollution. An oil spillage spells a catastrophe for the environment. The worst disaster was in 1989, when 11 million gallons of oil leaked near the banks of Alaska. As a result, thousands of birds and animals died. An oil spillage spells a catastrophe for the environment.

12 Solutions Alternative forms of transport (limit the number of vehicles on the roads and increase public transport). Alternative forms of transport (limit the number of vehicles on the roads and increase public transport). Alternative energy sources (energy like wind power, solar panels, tidal power, geothermal energy). Alternative energy sources (energy like wind power, solar panels, tidal power, geothermal energy). Green products (recycled products). Green products (recycled products). Building of refineries. Building of refineries.

13 Noise pollution is a displeasing human- or machine-created sound that disrupts the activity or balance of human or animal life. is a displeasing human- or machine-created sound that disrupts the activity or balance of human or animal life. Sources of noise pollution: road traffic road traffic airports airports factories factories phones phones TV/radio TV/radio

14 Effects on humans Damage to hearing Damage to hearing Stress Stress Annoyance Annoyance Anxiety Aggression Depression

15 Ways to reduce and protect yourself from noise pollution Turn down TV or radio. Turn down TV or radio. No loud toys. No loud toys. Use one appliance at a time. Use one appliance at a time. Settle down far from main roads. Settle down far from main roads.

16 Waste pollution Waste, rubbish, trash, garbage, or junk is unwanted or undesired material. Waste, rubbish, trash, garbage, or junk is unwanted or undesired material. It causes an increase in mortality or an increase in serious illness; or pose potential hazard to human health or the environment when it is improperly treated, stored, transported, or disposed.

17 Deforestation is the disappearance of forests from large parts of the worlds surface. is the disappearance of forests from large parts of the worlds surface. Less and less oxygen is being produced. Less and less oxygen is being produced.

18 Extinction Humans cut down many trees, therefore, it disturbs the natural habitat of the animals. If we continue to cut down too many trees we may have an extinct animal before we know it.

22 The total amount of radiation released will never be known, but it is hundreds of times greater than that released by the atomic bombing of Hiroshima and Nagasaki. The total amount of radiation released will never be known, but it is hundreds of times greater than that released by the atomic bombing of Hiroshima and Nagasaki. The countries worst affected by the radiation: The countries worst affected by the radiation: Ukraine, Belarus,Russia, Georgia, Poland, Sweden, Germany, Turkey and even the US and Japan.
