  1. 1. What are the effects of the global warming on water management?
  2. 2. Introduction: Global Warming <ul><li>Nowadays the world is warming, especially due to the human activity.
  3. 3. There are lots of consequences.
  4. 4. We will explain to you one of them. </li></ul>
  5. 5. Consequences of melting of iceberg
  6. 6. The consequences are : - Less drinking water - Increase in the salt water surface - Less icebergs
  7. 7. There are a lot of solution but we will base ourselves more particularly on the transformation of salt water into drinking water and the collection of water.
  8. 8. For the tranformation in drinking water we found a solution : <ul><li>Factories of desalinazation plans :
  9. 9. These factories used two methods :
  10. 10. The vacuum distillation, we heat the water until it boils and evaporates, which leaves the salts and minerals under. </li></ul>
  11. 11. <ul><li>The second method is the filtering of water with very  thin membranes where only water can pass through . </li></ul>
  12. 12. Vd But the drinking water from these factories are often use to irrigate fields. And the desalinazation is very expensive because it needs a lot of electricity. But the salt can be sold.
  13. 13. Second solution We can also collect the rain in tank which we can use to irrigate field. (Fields use 70% of water consomation) We can't drink it because there aren't minerals .
  14. 14. Conclusion The only solution if we don't stop the global warming is to save drinking water and use rain and desalinated water to irrigate fields. Save me, stop the global warming !
