  2. 2. CAUSES
  3. 3. CHLOROFLUOROCARBONS .(CFCs) <ul><li>Chlorofluorocarbons (CFCs) are gases used in refrigerant and aerosols: a gas containing carbon (sometimes hydrogen,) chlorine, and fluorine, used as a refrigerant and aerosol propellant. </li></ul>
  4. 4. CARBON DIOXIDE EMISSIONS CARBON DIOXIDE is ( chemical formula : CO 2 ) is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure .
  5. 5. DEFORESTATION <ul><li>Deforestation is the conversion of forested areas to non-forested areas. The main sources of deforestation in the Amazon are human settlement and development of the land </li></ul>
  6. 6. CENTRAL HEATING A central-heating system provides warmth to the whole interior of a building (or portion of a building) from one point to multiple rooms.
  7. 7. Littering can be considered the most visible form of solid waste pollution .The act of littering for the most part constitutes disposing of waste inappropriately, typically in public places. LITTERING
  9. 9. GLOBAL WARMING Global warming is the increase in the average temperature of the Earth 's near-surface air and oceans since the mid-20th century and its projected continuation.
  10. 10. OZONE LAYER HOLE Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total volume of ozone in the Earth´s stratosphere.
  11. 11. Greenhouse effect The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun.
  12. 12. Desertification D esertification is the degradation of land in arid and drysu-humid areas, resulting primarily from natural activities and influenced by climaticvariations
  13. 13. Poles melting Melting of continental Antarctic ice could contribute to global sea level rise.
