POLLUTION AND CONSERVATION Made By : Hitarth
MAJOR KINDS OF POLLUTION……1. Air Pollution 2. Water Pollution3. Soil Pollution4. Noise Pollution
AIRPOLLUTION
AIR POLLUTION…….
CausesBurning Of
Fuels Exhaust Gases Others
Sulphur Dioxide
Carbon Monoxide
HydrocarbonsOxides Of Nitrogen Carbon Dioxide
Lead Used In Gasoline
HARMFUL EFFECTS……1. Air Pollution Is Responsible For Thousands Of Death
Every Year.2. Old People Are Highly Vulnerable.3. Older People With Heart Or Lung Disorders Are
Under Additional Risk.4. Children And Infants Are Also At Risk.
HOW…..1. Carbon Dioxide Reduces Amount Of Oxygen In Body Which
Causes Headache.2. Nitrogen Oxides Causes Acid Rain, Damages Plants And
Irritates Nose-eye.3. Carbon Monoxide Is A Poisonous Gas Which Causes
Irritation, Blackout Or Death4. Hydrocarbons May Cause Cancer5. Nitrogen Oxide Combines With Hydrocarbons Which Forms
Peroxyacetyl Nitrate Which Irritates Eye And Lungs.
PREVENTION…….1. Factories And Industries Should Be Away From The Cities.2. Tall Chimneys Should Be Made3. Tetraethyl Should Be Added To Petrol Or Unleaded Petrol
Should Be Used.4. More Growth Of Trees5. Non Conventional Sources Of Energy Should Be Used6. Use Of Solar Heaters, Cookers, Biogas, And Smokeless
Stoves Should Be Encouraged7. Use Of Public Transport.
W A T E R P O L L U T I O N
CAUSES1. Atmospheric Pollution Each Time Oxides Of Nitrogen And Sulphur Are
Released Into The Air, They Form Acid Rain. This Acid Rain Falls Into Water Bodies And
Contaminates The Water With Sulphuric Acid And Nitric Acid.
CONTD…….2. Ocean And Marine Dumping It Is Said That Paper Takes 6 Weeks To Decompose
And Aluminium Takes 200 Years. When This All Ends Up In The Sea, It Is Very Harmful
For All Living Organisms.
CONTD…..
3. Industrial WasteRelease Of Chemicals From The Industries Cause Huge Water Pollution With Their Activities.
HARMFUL EFFECTS1. Reduces Amount Of Oxygen In Water.2. Results In Water–Borne Diseases. Eg: Jaundice3. Acid Rain4. Deals Great Damage To Aquatic Life.5. Disruptions In Food chains6. Damages Ecosystem
PREVENTION1. Chemical Waste Should Not Be Dumped Into Water.2. No Establishment Of Industries On Water Bank.3. Contaminated Water Should Be Purified Before Releasing It
Into Water.4. No Dumping Of Oil In Seas By Ships Or Tankers.5. No Releasation Of Organic Waste Into Water Bodies.6. Establishment Of Solar Power Stations To Decrease Thermal
Power Pollution.7. Dams And Reservoirs Should Be Built For Controlling Flood8. Minimum Use Of Fertilizers And Pesticides.
SOIL POLLUTION Soil Depletion The
elimination of minerals and nutrients from soil is called soil depletion.
Soil Erosion A process in
which the top soil is eroded and taken away with either water or wind, taking away minerals is called erosion.
CAUSES……1. Domestic Waste2. Littering Of Plastic, Glass, Other Non-biodegradable
Things3. Throwing Of Things Made Of Heavy Metal, Etc
FACTThe
average time of using a plastic bag is just 12 seconds. So many plastic bags!!!!!!!!!!!
PREVENTION……1. Less Cutting Of Trees2. More Planting Of Saplings3. Plants Like Bamboo And Eucalyptus Keep The Soil Firm,
Thus They Should Be Planted To Minimize Soil Erosion.4. Plants, If Planted In A Row, Break The Force Of Wind, Thus ,
There Is No Loss Of Topsoil.5. Terrace Farming Should Be Practiced6. Crop Rotation Should Be Followed7. Agricultural Land Should Be Utilised At Maximum.
CAUSES…..1. Jet Planes2. Motor Vehicles3. Television4. Radio5. Construction Machinery6. Siren7. Crackers
PREVENTION……1. Reduction of noise produced by house products2. Maintenance of automobiles3. Low voice4. Prohibition of loudspeakers5. Selection of machinery6. Maintenance of machinery
EFFECTS……1. Loss Of Hearing2. Sleeplessness3. Depression4. Irritation5. Headache6. Blood Pressure
THE CHIPKO ANDOLAN In the 1970s, an organized resistance to the destruction of forests spread throughout India and came to be known as the Chipko movement.
The name of the movement comes from the word 'embrace', as the villagers hugged the trees, and prevented the contractors' from cutting them.
