Pollution causes, effects and solutions

  1. 1. Environmental Problem Pollution Mrs. FB Kh www.physique48.org
  2. 2. Planet Earth is the only planet where life exists. Mother Earth
  3. 3. Planet Earth is where we live.
  4. 4. Everything that surrounds us is:
  5. 5. Environment Trees Waters PlantsHumans Buildings Air Mountains Animals
  6. 6. What’ s happening to planet Earth? It’s heating up. It’s coughing. It’s melting. It’s wounded. is SICK
  7. 7. Mother Earth is DYING
  8. 8. WHO is killing Earth? and HOW?
  9. 9. M A N
  10. 10. Man is killing Earth by causing POLLUTION
  11. 11. What is Pollution happens when the environment is contaminated or dirtied by waste, chemicals, gases and other harmful substances.
  12. 12. There are four main forms of pollution Pollution Noise pollution Water pollution Air pollution Land pollution
  13. 13. Air Pollution
  14. 14. Air Pollution
  15. 15. Air pollution is actually harmful substances in the atmosphere which damages the environment. With the development of industries, came along the increase in air pollution.
  16. 16. Form Causes A cloud of smoke from the exhaust of a vehicle Increasing traffic Smoke from a factory chimney Growing cities Eruption of a volcano Rapid economic development Cigarette smoke Industrialization Burning leaves Apathetic people
  17. 17. Effects of Air Pollution -Health problems -Damage to the environment -Damage to property -Thinning of the protective ozone layer of the atmosphere which is leading to climate changes
  18. 18. Birth defects cancer Respiratory problems Heart diseaseAsthma Tuberculosis Immune system damage Intellectual disorders
  19. 19. Some Solutions to Air Pollutionshould / share vehicles or use public transport to go to work should / get a regular pollution check for our vehicles should / walk or use bicycles to go to near places chimneys of factories should be fitted with proper filters to prevent smokes from coming out and effect the atmosphere conserve energy:switch off fans and lights when you are going out
  20. 20. Water Pollution
  21. 21. Water Pollution
  22. 22. Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.
  23. 23. Form Cause Toxic substances dissolve in water or gets deposited on the bed. City sewage Toxic substances enter lakes, rivers, streams, etc. Industrial waste Pollutants go down into the ground. Agricultural run-off
  24. 24. Effects of Water Pollution Devastating to people and animals, fish, and birds. Unsuitable for drinking, recreation, agriculture, and industry. Destroys water life.
  25. 25. Diarrhea Vomiting Typhoid Diphtheria Hepatitis Kidney Damage Nerve Disorders Skin Lesions
  26. 26. Some Solutions to Water Pollution Factories should not throw their wastes in water bodies People should not bath or wash clothes in rivers or lakes People should not take their animals to bath in riversor lakes
  27. 27. Land Pollution
  28. 28. Land Pollution
  29. 29. is the degradation of Earth's land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly. Health hazard disposal of urban and industrial wastes, exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few factors.
  30. 30. Types of waste Household waste Industrial waste Biomedical or hospital waste Causes Population increases Increased plastics products Changes in lifestyle Landfills not well equipped to protect against contamination
  31. 31. Effects of Land PollutionOver a long period of time, landfills start to emit landfill gases. Landfill gas is produced due to the anaerobic conditions that organic wastes decomposed in. Most waste buried in landfills give rise to hazardous and toxic liquids known as leachates. These leachates contaminate water sources, like the ground water below the landfills, leading to water pollution. Besides the points mentioned above, it is also important to note that these over-crowded dumps, contaminated sites and careless disposal of waste also contributes to air and water pollution, as well as, acid rain.
  32. 32. Since direct impacts of land pollution are air pollution and water pollution, the key health problems caused by land pollution are same as those of air pollution and water pollution and the additions are increased human injuries, from syringes, broken glass and cans washing onto river banks and beaches.
  33. 33. Some Solutions to Land Pollution People should plant more trees People should not throw rubbish in the streets , instead they should use litter bins Industries should not throw their wastes on land
  34. 34. Noise Pollution
  35. 35. Noise Pollution
  36. 36. Sound is essential to our daily lives, but noise is not. Noise is generally used as an unwanted sound, or sound which produces unpleasant effects and discomfort on the ears.
  37. 37. Causes -Road traffic -Factories -Loud speakers and other loud speaking things -Jet planes -Cinema halls -Household equipments -Plumbing, boilers, generators… Effects Temporary or permanent deafness Headaches and earaches The physiological manifestations are stress, irritability and nervousness, feeling of fatigue and decreases work efficiency.
  38. 38. Some Solutions to Noise Pollution People should not use lous speakers Factories should be made out of the cities There should not be more noise making vehicles on the roads
