  3. 3. All living beings on earth breath in oxygen and breath out carbon dioxide during respiration.
  4. 4. Traffic emits carbon dioxide into the atmosphere
  5. 5. Trees and vegetation absorb carbon dioxide and release oxygen during photosynthesis
  6. 6. Thus cleaning the air for other living beings, they are often called the LUNGS OF THE EARTH
  7. 7. When we cut trees and clear vegetation. We reduce this cleaning process, carbon dioxide increases at the rate of half a year. THE GREEN HOUSE EFFECT results.

  11. 11. THE EARTH becomes warmer , just like a GREENHOUSE
  12. 12. The ozone layerprotects the earth by filtering the harmful ultravioletrays from the sunlight falling on earth.When man-made chloroflorucarbons destroy the Ozone layer.More ultraviolet radiation will penetrate to the Earth and cause human health problems and damage food crops.
  13. 13. When it is destroyed more ultraviolet rays will fall on earth and cause problems to human health such as: Acute sunburn, Premature aging of the skin Skin cancer, nutritional disorders Susceptibility to infections,
  14. 14. Polar ice caps melting
  15. 15. Spread of diseases
  16. 16. More water and more hurricanes
  17. 17. Increase probability and intensity of drought and heat waves
  18. 18. Economic consequences
  19. 19. Deforestation in Iguaco South
