Chap 3 environment

  1. 1. 3.1.3 : Natur alDisaster
  2. 2. Floods  Can cause erosion and landslides  Destroy crops, livestocks, properties and spreads disease
  3. 3. Drought Land hard and dry Plants will die and will disrupt the food web
  4. 4. Volcanic eruption  Choking clouds of dust and poisonous gases  Can cause acid rain and air pollution
  5. 5. Earthquakes Destroy building, properties, animals, plants and people Can cause tsunami, hurricanes, typhoons or cyclones.
  6. 6. Tsunami
  7. 7. Hurricane
  8. 8. Typhoons
  9. 9. Cyclones
  10. 10. 3.2 T he Sour ce ofEnvironmental Pollution
  11. 11. Sources ofenvironmentalpollution Uncontrolled used of fossil fuels Disposal of by-products, waste, toxic substance, radioactive substance, smoke and heat from factories Uncontrolled use of chemical fertilizers, pesticides and fungicides in agriculture
  12. 12. Sources ofenvironmentalpollution Production of noises, smoke and poisonous gases from vehicles and machinery Disposal of rubbish and sewage Use of chlorofluorocarbon (CFC)
  13. 13. Effects ofenvironmentalpollution Human health Loss of habitat and change in natur Extinction of species Loss of economic resources
  14. 14. The Greenhouse EffectNatural heating process thatoccurs when certain gases(greenhouse gases) in theEarth’s atmosphere trap heat.
  15. 15. Greenhousegases Carbon dioxide – main greenhouse gas which come from the burning of fossils fuels and deforestation Methane, chlorofluorocarbon (CFC), ozone and nitrogen oxides.
  16. 16. Global Warming Average global temperature of Earth is rising This could cause extensive melting ice caps and glaciers and raise sea levels It will change weather patterns and effect agricultural output.
  17. 17. The Ozone Layer Ozone layer contains a high concentration of ozone and serves to shield living organism from the Sun’s harmful energy Ozone absorbs most of the ultraviolet radiation that enters the atmosphere.
  18. 18. Coolant Refrigerators Air-Conditioner CFC’sPropellants Styrofoam Spray cans/ aerosols
  19. 19. Effect of OzoneDepletion  Irritation of eyes, throat and lung cancer
  20. 20.  Reduce the yield of crops
  21. 21.  Sunburn
  22. 22.  Skin cancer
  23. 23.  Cataract
  24. 24.  Mutation - Down’s Syndrome
  25. 25.  Impairs crop and tree growth Kill phytoplankton that sustain oceanic life
  26. 26. The Idea of Preservation and Conservation of the Environment and Pollution Control Preservation  To keep something the same or prevent it from being damaged. Conservation  Carefully using valuable natural resources that they will be available for as long time as possible
  27. 27. The Importance of Proper Management of Natural Resource Forest reserve Develop new technology of fisheries Monitor an opening of a new land Carried out mining activities systematically
