pollution in egypt ( final draft )

                      Pollution has become a major issue over the years because it contaminates the earth's enviroment and affects human health . Air pollution is not a new topic . It is a problem that we have noticed since the industrial revolution when trees , houses and cars were covered in soot from the factories . Egypt suffers from all kinds of pollution , air pollution ,sound pollution and marine pollution but I'll write about air pollution as clean air is very important to live healthy .


                      The various causes of air pollution that releases harmful gases into the atmosphere are caused due to the increasing number of power plants and manufacturing units or industries that mostly have activities related to the burning of fuels . Besides, most automobiles, marine vessels and  activities that involve the burning of wood .  Fumes that are released from aerosol sprays . Military activities that involve the use of nuclear weapons . All are the numerous causes of air pollution .


                      Air pollution is actually the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life .With the development in industry, came along the increase in air pollution, which occurs inside homes, schools, offices even in the countryside. Consequently there has been an increase in the death rates resulting from various diseases caused by air pollution varying from breathing problem to lung cancer. Air pollution does not only affect people but it also damages the whole ecological system in which plants and animals are harmed as well. Air pollution has reached such a critical stage where it affects the earth's atmosphere as it lets in more harmful radiation from the sun. Consequently, our polluted atmosphere is becoming a better insulator, thus, preventing heat from escaping back into space. That is why there is a global rise in temperature which scientists refer to as " global warming". As a result of this rise in temperature the world food supply and sea level will be affected, also there is the probability of increase in the tropical disease.


                      To sum up, air pollution is a very serious problem which threatens our lifes on earth, so people and government should co-operate to over come this problem .
