    • References
  • 3. Definition of Pollution
    • When harmful substances contaminate the environment it is called pollution
    • Pollution can take the form of chemical, substances or energy, such as noise, heat, or light
    • Pollution refers to the very bad condition of environment in terms of quantity and quality
  • 4. Types of Pollution
    • There are four types of Pollution
    • Air Pollution
    • Water Pollution
    • Noise Pollution
    • Land Pollution
  • 5. Air Pollution
    • Air Pollution is the introduction of chemicals, particulate matter or biological materials that cause harm or discomfort to Humans, other living organism or cause damage to the natural environment
  • 6. Causes Of Air pollution
    • Human Activities
    • Industries
    • Vehicle Exhaust
    • Energy Sources
    • Wild Fires
    • Volcano
    • Tornadoes
  • 7. Effects of Air Pollution
    • Greenhouse effect
    • Ozone depletion
    • Acidification
    • Smog formation
    • Eutrophication
    • Human health
    • Ecosystem health
  • 8. Prevention of Air Pollution
    • Always try to minimize smoke emission
    • Use alternative energy sources: Solar Energy, Wind energy
    • try to travel by public transports
  • 9. Water Pollution
    • The Contamination of water with undesirable substances which make it unfit for usage is termed water Pollution
    • Water pollution occurs when pollutants are discharge directly or indirectly into water bodies without adequate treatments to remove harmful compounds
  • 10. Sources of Water Pollution
    • Point Sources
    • Single large source
    • Can localize it to one spot
    • - Industrial Plants
    • - Sewage pipes
    • LUST - Leaky Underground Storage Tanks (Picture)
  • 11. Sources of Water Pollution
    • Non Point Sources
    • Diffuse source or many smaller point sources
    • Automobiles
    • Fertilizer on fields
  • 12. Causes of Water Pollution
    • Water Pollution is Caused by organic and inorganic industrial wastes and affluent discharged into rivers.
  • 13. Effects of Water Pollution
    • Spread of disease: cholera or typhoid infections, along with diarrhea.
    • Affects body organs
    • Suffocation of aquatic life through sediment and loss of water depth
    • Overgrowth of algae and surface life, leading to loss of light and nutrients to deep aquatic life
  • 14. How to Avoid Water Pollution?
    • Rivers should not be used for washing clothes or bathing animals in.
    • Harvesting of Rainwater to meet water requirements.
    • Dams &embankments must be created.
    • The rivers must not be contaminated.
    • In sacred river like Ganga the dead bodies shouldn’t thrown.
  • 15. Noise Pollution
    • Noise pollution is excessive , displeasing human, animal or machine created environment al noise that disrupt s the activity or balance of human or animal life
  • 16. Causes of Noise Pollution
    • Traffic noise
    • Aircraft Noise
    • Noise from construction and civil engineering works
    • Noise from the industries
    • Noise of the other sources
  • 17. Effect of Noise Pollution
    • Hearing Loss
    • High Blood Pressure
    • Stress
    • Sleep Disturb
    • Color Blindness
  • 18. How to Avoid Noise Pollution?
    • The Government should ensure the new machines that should be noise proof
    • Airports must be away from residential area
    • The sound horn symbol is to be in school
  • 19. Land Pollution
    • Land pollution is the degradation of Earth's land surfaces often caused by human activities and their misuse of land resources.
  • 20. Causes of Land Pollution
    • Mining and quarrying
    • Sewage waste
    • Household Waste
    • Industrial Waste
    • Use of Pesticides and herbicides in farming
  • 21. Pictures of Land Pollution
  • 22. Effects of Land Pollution
    • Exterminates wild life
    • Acid rain kills trees and other plants.
    • Vegetation that provides food and shelter is destroyed.
    • Can seriously disrupt the balance of nature.
    • pesticides can damage crops; kill vegetation; and poison birds, animals, and fish
