final draft(pollution)

final draft (pollution)
    I’ll go out for a breath of fresh air’ is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world, because the quality of air in our cities is anything expect  fresh. This is evident from the moment we step out of our house and are greeted with black colored smog that hits us directly reminding us that breathing clean air is more of a distant dream.Here is a look at the causes of air pollution, how it can affect us and how we can control it.

    What causes air pollution? Air pollution results mainly from carbon dioxide, fuels and industrial countries.Carbon dioxide gas is used in various industries such as the oil industry and the chemical industry.The manufacturing process of most products would require the use of this gas Scientists have now therefore identified carbon dioxide as one of those elements that have contributed to global warming.  Causes of air pollution are not limited to this.The burning of fossil fuels in big cities which is seen at most factories, offices and even a large number of homes.
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 burning of fuels.

        Air pollution has many disastrous effects,The major effects of air pollution are health,climate and property. people have to breathe the air around them regardless of its quality. When they breathe ground-level ozone or air with particulates, they do so at risk to their health.air pollution may causes many diseases such as,irritation to one’s eyes, throat, and lungs. coughing, burning eyes, headaches, and difficulty breathing. Moreover air pollution causes global warming due to greenhouse gases that released from cars and trucks.In fact, since cars were invented and factories and power plants were built,the earth will even get warmer and warmer.In addition to damaging the environment and human health, air pollution can harm buildings, monuments, outdoor statues, and other such structures.

         There are many ways that helps us to prevent or reduce air pollution,Trees give out oxygen and take in carbon dioxide and thereby clean the air around us. It is therefore our duty to take care of them.in addition to that People may try to restrict population growth, use less energy, improve energy efficiency, reduce waste, recycling the garbage instead of burning it.

        Finally, After talking about air pollution i hope that  every one realizes that he is responsible for the causes of air pollution and the situation that we face today so that every one should try to find solutions of air pollution. I think that there is one way to control pollution through the Kyoto Protocol, an agreement between countries that they will cut back on carbon dioxide , Another method is to put a higher taxes on gasoline.
