  8. 9. <ul><li>Coal burning for vehicles, power plants etc. </li></ul>- Global Warming & Climate Changes - Ozone hole - Greenhouse effect (Similar to global warming) - Diseases such as lung cancer, skin cancer etc. - Extinction due to sudden change in habitats <ul><li>Smoke </li></ul><ul><li>Natural Reasons- Volcanic eruptions, forest fires etc </li></ul>EFFECTS
  9. 10. AIR POLLUTION = KILLING YOURSELF! <ul><li>BUT!! If the Greenhouse Effect is too strong, the earth could; </li></ul><ul><li>Dry out </li></ul><ul><li>Climate Changes </li></ul><ul><li>Floods </li></ul><ul><li>Weather conditions like hurricanes. </li></ul>In Antarctica, there is a big hole in the ozone layer. The heat gets in, and the ice melts!!! Now, this is Global warming… <ul><li>Warming-up of certain gases in the atmosphere </li></ul><ul><li>The Greenhouse Effect traps the sun’s heat </li></ul><ul><li>It is called the “Greenhouse Effect” because it has the same effect as a greenhouse </li></ul>The Greenhouse Effect
  10. 11. <ul><li>- Earth’s temperature rises </li></ul><ul><li>Started 200 years ago </li></ul><ul><li>Greenhouse effect </li></ul><ul><li>Ozone hole- sources </li></ul><ul><li>Climate changes- acid rain </li></ul><ul><li>- Big changes; </li></ul><ul><li>Ozone Layer </li></ul><ul><li>Protects living creatures </li></ul><ul><li>Protects the surface of Earth </li></ul><ul><li>Absorbs 96% of the sun’s UV light </li></ul>Global Warming
  11. 12. We were putting up posters to reduce the amount of paper towels used. This will save trees, and we hope that many people will follow this! Carrying the action...
  12. 13. To help, you can: - Use major transportation - Try to avoid the use of cars (Walk, ride a bike, carpool) - Save energy by turning electric devices off when unnecessary - To Smoking Adults: Try not to smoke! It is bad for everything! - Recycle- It saves energy! Note: Pollution’s causes are mostly made by humans. This is how our responsibility shapes the future. In the past, certain advances have made life easier for people, but present human neglect of the environment has made the Earth look like the way it appears now. Conclusion
  13. 14. <ul><li>What percent of the sun’s UV rays does the ozone hole absorb? </li></ul><ul><li>a) 57% b) 96% c) 95% d) 40% </li></ul><ul><li>2) What is one cause of water pollution? </li></ul><ul><li>a) Runoff b) Computers c) Walkoff d)the smoke of industries </li></ul><ul><li>3) What can happen because of land pollution? </li></ul><ul><li>a) Global Warming b) Loss of Habitats c) Acid rain </li></ul><ul><li>4) What was our action? </li></ul><ul><li>a) Planting trees b) Putting up posters c) Decorating walls </li></ul><ul><li>5) Explain what The Greenhouse Effect is in a easy way. </li></ul>Quick Quiz
