Air pollution

 Air pollution is a worldwide problem. What is air pollution? It's the introduction of harmful substances or products into the enviroment which can occur naturally orartificiall 


y.here are two types of airpollution (primary )such as vehicle exaust , and secondary such as smogAir pollution is a dangerous threat caused by many different productions such as: car exhaust, Nitrogen Oxides and has a serious effect on us


 The first major cause of air pollution is car exhausts whichformed due to
 the production of unburned fuel in the form of oxides of Nitrogen and hydrocarbons.  The 


second cause of air pollution is Nitrogenoxides. Basically Nitrogen oxide is one of the harmful gases which is produced into the atmosphere due to various humanactivities such as burning of fuel. military activities ara one of the main causes that involve the use of nuclear weaponsthat pollute air.






Air pollution has wide adverse effects on the environment and man in general.   People have no choice but to breathe the air around them regardless of its quality.  Symptoms of air pollution exposure include irritation to one’s eyes, throat, and lungs. , headaches, and difficulty breathing are all commonly reported when air quality is poor. in addition to it reduced energy levels , disrupting the balance of nature, and leading to premature death.


Although people have no choice but to breath the air around them, they do have choices that can help them stay healthy. Paying attention to air quality forecasts,  
avoiding outside exercise or spending more time inside when ozone levels are high, and supporting measures to improve air quality and reduce sources of pollution are all  commendable and health-saving measures. i think that the solution isto save energy by trying to use minimum amountsof natural gas and even electricity, and avoidinf thr use of air conditioner and use afan instead.


 Air pollution is a problem that everyone should be concerned about. With the growing number of automobiles, and the greenhouse effect problem becoming more and more of a threat   


air,pollution is something to be concerned with
we need to avoid the use  of fire crackers that dont really need it to express our feeling of happiness , and also try reusing things such as paper , and plastic bags , this will contribute towards reducing the effects of air pollution and global warming.
