The Exhaustion of Water

  1. 1. Presentation by Andreas Constantinou and Kyriacos Andreou
  2. 2. Natural Resources <ul><li>Main Energy Sources : Water , Cultivated Land , Forests , Minerals , Ores , Solar energy etc . </li></ul><ul><li>Phenomenon of our times : Exhaustion of Natural Resources . </li></ul><ul><li>More serious parameter of phenomenon : The exhaustion of water </li></ul>
  3. 3. The available water <ul><li>97% is salty and is found in the oceans. </li></ul><ul><li>2 % is fresh and is found in rivers, lakes etc. </li></ul><ul><li>1% that remains covers our daily needs. </li></ul>
  4. 4. The distribution of water on earth <ul><li>Frozen form ( Ice ) </li></ul><ul><li>Humid form ( Water ) </li></ul><ul><li>Gases ( Water vapours ) </li></ul>
  5. 5. Consumption of water : in agriculture , industry , domestic use . <ul><li>70% of available water is used in agriculture . </li></ul><ul><li>Irrigation sources : Rain , Humidity of soil , Underground water . </li></ul><ul><li>Modern ways of culture . </li></ul>Agriculture :
  6. 6. Industry: <ul><li>Industry consumes 23% of available water . </li></ul><ul><li>Industries use water : For the production of electric energy , mining enterprises , treatment of raw materials . </li></ul><ul><li>Water is thrown away factory waste . </li></ul><ul><li>Phenomenon of acid rain </li></ul><ul><li>Only a small percentage is consumed completely </li></ul>
  7. 7. Domestic use:
  8. 8. Why do humans need water? <ul><li>66% of the human body is made up of water. </li></ul><ul><li>At just 2% dehydration your performance decreases by around 20% . </li></ul><ul><li>We should drink at least 1 ½ litres of water a day. </li></ul>
  9. 9. Access to safe water? <ul><li>The number of people with access to clean water has doubled in the last 20 years. </li></ul><ul><li>1.1 billion people in the world still do not have access to safe water. This is nearly 20% of the population. </li></ul>
  10. 10. Forecast for the future <ul><li>Water : An element of extinction . Future wars will take place in order to guarantee water for their country . </li></ul><ul><li>In poor countries the problem is more intense. </li></ul><ul><li>Demographic increase , pollution and minimal education in developing countries overloads the problem and offers almost no solution . </li></ul><ul><li>80% of all illnesses in developing countries is caused by water related diseases. </li></ul><ul><li>90% of wastewater in developing countries is discharged directly into rivers and streams without treatment. </li></ul>
  11. 11. Conditions for the guarantee of Water in the future <ul><li>Exploitation of technological achievements- contract agreements . </li></ul><ul><li>Desalination of water </li></ul><ul><li>Water: Improve its quality . </li></ul><ul><li>Imposing penalties in industries that increase and accelerate water pollution. </li></ul><ul><li>Proposals for adoption of more economic methods of operation by the enterprises (recycling of water). At home use a bucket and not running water to wash dishes or fruit. Then use the water for watering the garden. </li></ul>
  12. 12. <ul><ul><li>An average bath uses 80 litres of water but </li></ul></ul><ul><ul><li>an average shower only uses 35 litres . Have a shower, don’ t have a bath. </li></ul></ul><ul><ul><li>Do you leave the tap on when you clean your teeth? If so, then you waste 5 litres of water. You only need ¼ litre of water if you turn the tap off ! Try it. It works! </li></ul></ul><ul><ul><li>Use the water that you washed your fruit and vegetables in, to water your plants in the garden. Use a watering can instead of the hose to water your garden. It saves water! </li></ul></ul><ul><li>Saving water at home: </li></ul>
  13. 13. <ul><li>Use a Bucket: </li></ul><ul><li>Use a bucket instead of a hose with running water to wash your car. </li></ul><ul><li>You would be amazed at how much water you save! </li></ul>
  14. 14. Think of the future: <ul><li>The UN estimates that by 2025, 75% of the world population won’t have reliable, clean water. </li></ul><ul><li>Isn't it time we all did something about it? </li></ul><ul><li>Try it, it can be done! </li></ul>
