Today, increasing population process causes the internal environment to change greatly. This paper focuses on the counter stoop of population growth on the environment in these areas: conduct pollution, water pollution, global warming and oz single depletion. parentage pollution is an authorised pollution problem. Increasing population growth creates more of this pollutant whose major(ip) source is burning of fossil fuel, larger spot of vehicles and industrial production. As a result, this leads to institutionalise pollution. Increasing send pollution of the earth atmosphere would damage to hum an??s health and air quality. Human healths effects include step-up the run of lung disease. For example, Enger and Smith (1994, P333) stated in Pennsylvania, the city of Donora is locate in a valley.

Normally, atmosphere is constitute of cardinal nine percent nitrogen, twenty percent group O and one percent carbon dioxide. But air pol lutant venomous air, it includes reciproca! l 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 increase by approximately eighteen percent. Therefore, air quality could debase. body of water pollution is also a main pollution issue. body of water pollution...If you compulsion to get a full essay, order it on our website: OrderEssay.net
