  • 1. Presentation by Andreas Constantinou and Kyriacos Andreou
  • 2. Natural Resources
    • Main Energy Sources : Water , Cultivated Land , Forests , Minerals , Ores , Solar energy etc .
    • Phenomenon of our times : Exhaustion of Natural Resources .
    • More serious parameter of phenomenon : The exhaustion of water
  • 3. The available water
    • 97% is salty and is found in the oceans.
    • 2 % is fresh and is found in rivers, lakes etc.
    • 1% that remains covers our daily needs.
  • 4. The distribution of water on earth
    • Frozen form ( Ice )
    • Humid form ( Water )
    • Gases ( Water vapours )
  • 5. Consumption of water : in agriculture , industry , domestic use .
    • 70% of available water is used in agriculture .
    • Irrigation sources : Rain , Humidity of soil , Underground water .
    • Modern ways of culture .
    Agriculture :
  • 6. Industry:
    • Industry consumes 23% of available water .
    • Industries use water : For the production of electric energy , mining enterprises , treatment of raw materials .
    • Water is thrown away factory waste .
    • Phenomenon of acid rain
    • Only a small percentage is consumed completely
  • 7. Domestic use:
  • 8. Why do humans need water?
    • 66% of the human body is made up of water.
    • At just 2% dehydration your performance decreases by around 20% .
    • We should drink at least 1 ½ litres of water a day.
  • 9. Access to safe water?
    • The number of people with access to clean water has doubled in the last 20 years.
    • 1.1 billion people in the world still do not have access to safe water. This is nearly 20% of the population.
  • 10. Forecast for the future
    • Water : An element of extinction . Future wars will take place in order to guarantee water for their country .
    • In poor countries the problem is more intense.
    • Demographic increase , pollution and minimal education in developing countries overloads the problem and offers almost no solution .
    • 80% of all illnesses in developing countries is caused by water related diseases.
    • 90% of wastewater in developing countries is discharged directly into rivers and streams without treatment.
  • 11. Conditions for the guarantee of Water in the future
    • Exploitation of technological achievements- contract agreements .
    • Desalination of water
    • Water: Improve its quality .
    • Imposing penalties in industries that increase and accelerate water pollution.
    • 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.
  • 12.
      • An average bath uses 80 litres of water but
      • an average shower only uses 35 litres . Have a shower, don’ t have a bath.
      • 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!
      • 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!
    • Saving water at home:
  • 13.

  • 14. Think of the future:
    • The UN estimates that by 2025, 75% of the world population won’t have reliable, clean water.
    • Isn't it time we all did something about it?
    • Try it, it can be done!
