Water pollution
       

       Water is the prime element responsible for life on earth. It covers two thirds of the earth's surface. Also the human body consists of 75% of it. In the body it regulates fluids, cells and blood, and other activities. So, without water there is no life.

         Because of the recent developed technology, our water has become in danger. There are many reasons for this. Firstly, farmers use chemicals to kill bugs, fight diseases and to enhance the growth of their crops. These chemicals run into lakes or rivers and cause water pollution. Secondly, oceans are polluted by oil, spilled from ships. Thirdly, sewages and wastewater are another factor of polluting water, as in Egypt and other countries the best way to get rid or these wastes is by dropping them in seas, rivers and lakes.  Fourthly, dumping rubbish and wastes in the sea, which are eaten by marine animals, causes them to die.
      
         Resulting from the previously mentioned reasons of water pollution, our environment and health have been affected. The food chain is damaged, as humans eat the infected meat of marine animals they caught from polluted water. Also many infectious diseases can be contracted from drinking contaminated water. The infection of water can also alter the temperature of water and cause a large number of marine animals to die.
    
         As water is an essential factor in our life, and as being responsible for this crisis, we should find an urgent solution for this problem. For example farmers have to use safe materials to irrigate and treat their crops. The government should prevent factories and ships from dropping any wastes into water and make them pay fines if they don't. Sewages also have to be treated rather than dropping it into water. Using an ozone generator to break down pollutants would be very helpful to solve the problem too.

         To conclude, water is very important in our life, so we should take a good care of it. We should look for the reasons how it is polluted, and find solutions to solve them. Then we have to gather our efforts together to prevent the problem from happening again.
