  1. 1. ENVIRONMENTAL POLLUTION
  2. 2. TOPIC ENVIRONMENTAL POLLUTION Group member Sehrish Shahid 13024854- 115 Atika Riaz 13024854085 Ansa Arshad 13024854- 091
  3. 3. CONTENT OF ENVIRONMENTAL POLLUTION  Introduction  Kinds of environmental pollution  Effect of environmental pollution  Causes of environmental pollution  Prevention of environmental pollution
  4. 4. INTRODUCTION OF ENVIRONMENTAL POLLUTION Our environment is a major aspect of our life today. Many of us don't take our Earth seriously and think that as long as pollution doesn't hurt them they can go ahead and throw garbage on the ground or spill oil down the drain. Well to many people have that theory and they are killing off our Earth and also physically harming themselves from the air they breath and the water they swim in. Our Earth is fragile like a human and people don't know.
  5. 5. DEFINITION OF ENVIRONMENTAL POLLUTION Environmental pollution is the build-up and concentration of toxic levels of chemicals in the air, water, and land, which reduces the ability of the affected area to support life. Pollutants may be gaseous- ozone and carbon monoxide, for example; liquid discharge from industrial plants and sewage systems; or solid-landfills and junkyards.
  6. 6. KINDS OF ENVIRONMENTAL POLLUTION There are actually SEVEN different kinds of environmental pollution. Most people can name them are; o Air pollution o Land pollution o Water pollution o Noise pollution o Light pollution o Thermal pollution o Visual pollution Listed below are each kind and examples to help you understand just how we can affect the environment and each other.
  7. 7. AIR POLLUTION DEFINITION; AIR POLLUTION IS THE CONTAMINATION OF AIR BY SMOKE AND HARMFUL GASES, MAINLY OXIDES OF CARBON, SULFUR, AND NITROGEN.
  8. 8. EXAMPLE OF AIR POLLUTION Some examples of air pollution include:  Exhaust fumes from vehicles  The burning of fossil fuels, such as coal, oil or gas  Harmful off- gasing from things such as paint, plastic production and so on  Radiation spills or nuclear accidents  Air pollution is linked to asthma, allergies and other respiratory illnesses.
  9. 9. CAUSES OF AIR POLLUTION Major sources of air pollution are; o Industries o Smoke o Mist o Carbon black o Aerosols o Dust o Automobiles and domestic fuel o High proportion of undesirable gases
  10. 10. EFFECT OF AIR POLLUTION Air pollution effect?  Human health  Animal  Plants  The atmosphere  Global warming  Acids rains  Ozone depletion  Various respairatly illness
  11. 11. PREVENTION OF AIR POLLUTION Air pollution prevention?  Local controls  Dark smoke  Boilers and furnaces
  12. 12. EXAMPLE OF LIGHT POLLUTION; Some examples of what causes light pollution:  Street lamps that shine light in all directions, instead of with a hood to point light downward toward the street.  Unnecessary lights, especially around the home Light pollution uses more energy (by shining more light up instead of down), may affect human health and our sleep cycles and most importantly, corrupts our kids telescopes and their curiosity. Wastage of light pollution
  13. 13. CAUSES OF LIGHT POLLUTION
  14. 14. EFFECT OF LIGHT POLLUTION;
  15. 15. PREVENTION OF LIGHT POLLUTION;
  16. 16. LAND POLLUTION DEFINITION; Land pollution is the degradation of the Earth's surface caused by a misuse of resources and improper disposal of waste.
  17. 17. EXAMPLE OF LAND POLLUTION Some examples of land pollution include:  Litter found on the side of the road  Illegal dumping in natural habitats  Oil spills that happen inland  The use of pesticides and other farming chemicals  Damage and debris caused from unsustainable mining and logging practices  Radiation spills or nuclear accidents
  18. 18. CAUSES OF LAND POLLUTION Four main causes of land pollution are  Construction  Agriculture  Domestic waste  Industrial waste
  19. 19. EFFECT OF LAND POLLUTION These are the effect of land pollution;  The land cannot used to built houses  Man cannot farming  Ground water will get effected  Death of the animal that inhabit the land
  20. 20. PREVENTION OF LAND POLLUTION  Good agriculture practice  Trees should be planted everywhere  Waste matter should be disposed immediately  Remediation of polluted soils  Avoid using more fertilizers  prevention of erosion and silting 3R PRINCIPAL REDUCE REFUSE RECYCLE
  21. 21. WATER POLLUTION DEFINITION; Water pollution is the contamination of any body of water (lakes, groundwater, oceans, etc)
  22. 22. EXAMPLE OF WATER POLLUTION Some examples of water pollution:  Raw sewage running into lake or streams  Industrial waste spills contaminating groundwater  Radiation spills or nuclear accidents  Illegal dumping of substances, or items in bodies of water  Biological contamination, such as bacteria growth
  23. 23. CAUSES OF WATER POLLUTION  Agriculture waste water  Oil spills  Mining  Trash on common roads  Refineries  Industries process  Natural factors effect ground water
  24. 24. EFFECT OF WATER POLLUTION;  Malaria  Diseases like cholera  Typhoid (spread during the rainy season)  Aquatic life gets destroyed
  25. 25. PREVENTION OF WATER POLLUTION;  Factories should not throw there waste in water bodies  People should not bath and wash clothes in rivers and lakes  People should not take there animal to take bath in rivers or lakes
  26. 26. NOISE POLLUTION DEFINITION  Noise pollution is any loud sounds that are either harmful or annoying to humans and animals.
  27. 27. EXAMPLE OF NOISE POLLUTION  Some examples of noise pollution:  Airplanes, helicopters and motor vehicles  Construction or demolition noise  Human activities such as sporting events or concerts
  28. 28. CAUSES OF NOISE POLLUTION  Traffic noise  Air craft noise  Noise from construction  Noise from the industries  Noise from the other sources
  29. 29. EFFECT OF NOISE POLLUTION  Herring loss  Stress  High blood pressure  Sleep disturbance  Colour blindness
  30. 30. EFFECT OF NOISE POLLUTION
  31. 31. PREVENTION OF NOISE POLLUTION  Pleasant home  We need to talk sweetly to other  Talk less more work  Sound effect of ears so loud noise should be avoided  Bhagvan baba says that ‘’ silent is god’’
  32. 32. THERMAL POLLUTION DEFINITION;  Thermal pollution is the increase of temperature caused by human activity.
  33. 33. EXAMPLE OF THERMAL POLLUTION  Warmer lake water from nearby manufacturing (using cool water to cool the plant and then pump it back into the lake)  Included in thermal pollution should also be the increase in temperatures in areas with lots of concrete or vehicles, generally in cities
  34. 34. CAUSES OF THERMAL POLLUTION  Nuclear power plants  Coal fired power plants  Industrial effluents  Domestic sewage
  35. 35. EFFECT OF THERMAL POLLUTION  Change dissolved oxygen  Economic and environmental damage  Decrease in productivity of the water body  Changes in migration time and pattern may be effected  Death of steno hermetic animals  production of heat shock proteins for thermotolerance.
  36. 36. PREVENTION OF THERMAL POLLUTION
  37. 37. VISUAL POLLUTION DEFINITION; Visual pollution is what you would call anything unattractive or visualizing damaging to the nearby landscape. This tends to be a highly subjective topic, as we all find different things attractive and unattractive.
  38. 38. EXAMPLE OF VISUAL POLLUTION Some examples of visual pollution:  Skyscrapers might block the view of a mountain  Graffiti or carving on trees, rocks or other natural landscapes  Billboards, litter, abandoned homes and junkyards could also be considered among three kinds of environmental pollution
  39. 39. CAUSES OF VISUAL POLLUTION  SOURCES OF VISUAL POLLUTION;  POWER LINES  CONSTRUCTION AREIA  BILL BOARDS AND ADVERTISING
  40. 40. EFFECT OF VISUAL POLLUTION  PEOPLE WANTED TO GO TO THAT PLACES BUTS ITS WRITING ALL OVER  NOT KNOWING WHTS THE DRAWING MEAN  UNTIDYNESS  POLICE SEEING THEM DOING IT AND NOT DOING ANYTHING AT ALL ABOUT IT
  41. 41. PREVENTION OF VISUAL POLLUTION  Nuclear power plant  Deforestation  Soil erosion
