Abstract: | 自十九世紀工業革命後,全球工業的急速發展、人口的增加、經濟活動的頻繁,使全球工業污染物不斷地以等比級數的增加。再者,由農業上使用農藥及農業產生的廢物也顯著地增加污染物,導致全球生態上的變化。這些污染物可歸類出空氣污染物、水污染物、固體污染物及核能廢棄污染物。每種污染物都會對人類及其他生物生存造成威脅,並導致全球農業生產力的降低。尤有進者,山於工商業的發達及人類對自然資源無止境的開採利用,如森林的砍伐,石油的燃燒,煤礦的開採利用,在在使其燃燒後的二氧化碳量快速的增加。從1950年代的315ppm到1975年時的335ppm,二氣化碳雖不是污染物質,但全球二氧化碳的增加,使大氣的溫度隨之升高,造成溫室效應,並導成全球氣候的變遷。氣候的變遷當然會影響到全球農業的生產力。因此,不管空氣、水、固龍或核能的污染都造成農業問題。大地中二氣化碳、CFCs、甲烷、NOx、氟化物等,造成全球變遷所導致農業生產力的銳減更不可不慎。因此,全球科學家已焦注於『全球變遷(Global change)」的研究,以謀改善之道。 Air pollutants arc any gases or particulates in the atmosphere that cause discomfort for living organisms, or even their injury or death. Most common air pollutants, such as SO2, 03, PANs, NOx, NH3, ethylene, floride, gaseous heavy metals, and dust, can affect the growth of plants and animals in aquatic and terrestrial ecosystems, resulting in a decrease of productivity or in the extinction of species. The air pollutants mixed with water vapor may form acidic precipitation that will change soil properties and reduce water p11; consequently both forest and marine ecosystems are deteriorated. The change of hydrological cycle will lead to climatic changes that further influence the flora and fauna of the biosphere. All of the changes will result in the destruction of sustainable agriculture, and eventually threaten the survival of living organisms including humankind. |
