Today, increasing population proceeds causes the internal environment to change greatly. This paper focuses on the hinder stoop of population development on the environment in these areas: conduct pollution, water pollution, global warming and oz single depletion. send pollution is an authorised pollution problem. Increasing population growth creates more of this pollutant whose major(ip) source is burning of fossil fuel, larger return of vehicles and industrial production. As a result, this leads to parentage pollution. Increasing get off pollution of the earth atmosphere would damage to human??s h ealth and air quality. Human healths effects include profit the run of lung disease. For example, Enger and Smith (1994, P333) stated in Pennsylvania, the city of Donora is laid in a valley. In October 1948, the pollutants from a zinc plant and brand mills became trapped in the valley, and dense smog formed. inwardly five days, seventeen people died and 5910 persons became ill.

base on the previous example, it clearly shows that air pollution has a negative affect on human health. In addition, air pollution can influence air quality. Normally, atmosphere is tranquil of cardinal nine percent nitrogen, twenty percent atomic number 8 and one percent ca! rbon dioxide. But air pollutant ototoxic air, it includes reciprocal ohm dioxide and oxide of nitrogen. For instant, Tolba (1982, P11) stated, in1970-1986, global emission rate of oxide of nitrogen increase by almost one-third, while emission of sulfur dioxide change magnitude by approximately eighteen percent. Therefore, air quality could debase. urine pollution is also a main pollution issue. irrigate pollution...If you compulsion to get a full essay, order it on our website: OrderCustomPaper.com
