Environmental pollution is a term that refers to all the ways by which man pollutes his surrounding.Man dirties the air with gasses and smoke,poisons the water with chemicals and other substances,and damages the soil with too many fertilizers and pesticides.Man also pollutes his surrounds in various other ways.For example,people ruin natural beauty by scattering junk and litter on the land and in the water.They operate machines and motor vehicles that fill the air with disturbing noise.Nearly everyone causes pollution in some way.
Environmental pollution is one of the most serious problems facing mankind today.Badly polluted air can cause illness,and even death.Polluted water kills fish and other marine life.Pollution of soil reduces the amount of land available for growing food.Environmental pollution also brings ugliness to man's naturally beautiful world.
Water pollution reduces the amount of pure,fresh water that is available for such necessities as drinking and cleaning,and for such activities as swimming and fishing.The pollutants that affect water come mainly from industries,farm,and sewerage systems.Industries dump millions of tons of waste products into bodies of water each year.These wastes include chemicals,wastes from animal and plant matter,and hundreds of other substances.Wastes from farms include animal wastes,fertilizers,and pesticides.Most of these materials drain off farm fields and into nearby bodies of water.Sewerage systems carry wastes from homes,offices,and industries into water.
People,however,may differ in what they consider to be a pollutant,on the basis of their assessment of benefits and risks to their health and economic well-being.For example,visible and invisible chemicals spewed into the air or water from a plant nearby pose a danger to the people nearby and other animals and plants.However,if the installation of expensive pollution controls leads to the reduction of productivity,the unemployed might feel that the risks from polluted air and water are minor weighed against the benefits of profitable employment.The same level of pollution can also affect two people quite differently --- some forms of air pollution might be a slight annoyance to a health person but life threatening to someone with emphysema or another respiratory disorder.
环境污染是指人们用各种方式污染周围环境的一个术语.人们通过气体和烟雾来污染空气,用化学物质以及其他物质污染水源,还用大量的化肥和杀虫剂破坏土壤.人们还通过其他的方式污染着他们的环境.例如,总有人在地面上和水里扔垃圾,破坏自然美.人们使用的一些及其和交通工具噪音很大.可以说,几乎每个人都在某种程度上对周围环境造成了污染.
境污染是当今人们所面对的一个非常严重的问题.被严重污染的空气将引起各种疾病,甚至死亡.被污染的水源会引起鱼类以及其他海洋生物的死亡,被污染的土壤会减少种植农作物的面积.同时.环境污染使得人们周围美丽的自然环境日益变得丑陋.
水污染使得我们用来饮用和清洗的纯净新鲜的水资源不断减少,用于游泳、垂钓的水源也在减少.水的污染源主要来自工业、农场以及排水系统.工业废物每年数以千万吨计地被倾倒水中,这些废物包括化学原料,来自动植物的废物,以及上百种其他的废物.农场废物包括动植物排泄,化肥和杀虫剂.其中大部分物体都从田地里排出流入附近的水中.排水系统将来自每家每户,办公室和工业中的废水排到水中.
基于环境污染对人类健康和生活所带来的利弊的不同估计,人们对同一污染源持有不同的看法.例如,有形和无形的化学原料从附近的工厂排放到空气或水中,这对于附近的人们和其他的生物构成危害.但是,如果该工厂装备昂贵的控制污染的设备,导致生产成本提高,因此而失业的工人也许会觉得废气废水所造成的危险与具有丰厚利润的工作相比真是微乎其微.同种程度的污染对不同的人影响也不同.比如说,一些空气污染对于一个健康的人来说只是小烦恼,而对患有肺气肿或呼吸道疾病的人来说却是生死攸关的.
