Today, increasing population outgrowth causes the internal environment to change greatly. This paper focuses on the hinder stoop of population harvest-home 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 heel of vehicles and industrial production. As a result, this leads to note pollution. Increasing ambience pollution of the earth atmosphere would damage to human??s health and air quality. Human healths effects include increase the run of lung disease. For example, Enger and Smith (1994, P333) stated in Pennsylvania, the city of Donora is rigid in a valley.

ground 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 constitute of cardinal nine percent nitrog en, twenty percent type O and one percent ca! rbon dioxide. But air pollutant toxicant 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 change magnitude by almost one-third, while emission of sulfur dioxide increase by approximately eighteen percent.
