air pollution

       




   Although we suffer from many problems , pollution is the most dangerous one we face today.Pollution is one of the greatest dangerous of our modern technology .In fact, there are many kinds of pollution and I think air pollution is the most dangers one , as air supplies us with oxygen which is essential for our bodies to live. Unfortunately humans release substances into air that threaten our lives & cause disorder,instability,discomfort and harm to the living environment.




The are many causes of pollution .First of all the smoke of cars, factories, and the garbage which is thrown into streets .Carbon dioxide is also one of the main pollutants that causes air pollution.The manufacturing process of most products would require the use of this gas.Power plants and our reliance on fossil fuels for transportation make up the biggest percentage of air pollution. Another source of air pollution is the burning of solid waste. Although recycling is more popular nowadays than ten to twenty years ago, the amount of solid waste continues to rise each year.Also pollution can be created by indoor activites such as smoking and cooking .





 Pollution has a terrible effect on the people . Many different chemicals in the air affect the human body in negative ways and causes many dangerous diseases such as cancer, and heart diseases .Air pollutants such as ozone,and nitrogen oxides,also have harmful effects on nature.  They can kill plants and trees by destroying their leaves, and can kill animals, especially fish in highly polluted rivers.Also, high temperatures in recent years are due to the high proportion of carbon dioxide in the atmosphere.




   To solve this problem , factories should be built outside cities .Trees should be built everywhere to purify the atmosphere.Cars should be checked reguraly.The government should built new cities in the desert to relieve the pressure of the crowded cities.






  To sum up, I would like to say that breathing clean air is more of a distant dream.So we have to keep our environment clean to live happil.
