英语翻译
Natural environment
The deterioration of the natural environment is a major global concern.In many world cities,air and water pollution have reached dangerous levels.There is great concern about "greenhouse gases" in the atmosphere due to the burning of fossil fuels,about the depletion of the ozone layer due to certain chemicals,and about growing shortages of water.In Western Europe,"green" parties have vigorously pressed for public action to reduce industrial pollution.In the United States,experts have documented ecological deterioration,and watchdog groups such as the Sierra Club and Friends of the Earth carry these concerns into political and social action.
New regulations hit certain industries very hard.Steel companies and public utilities have had to invest billions of dollars in pollution-control equipment and more environmentally friendly fuels.The auto industry has had to introduce expensive emission controls in cars.The soap industry has had to increase its products' biodegradability.
SHORTAGE OF RAW MATERIALS The earth's raw materials consist of the infinite,the finite renewable,and the finite nonrenewable.Infinite.Resources,such as air and water,are becoming a problem.Water shortages are already a political issue,and the danger is no longer long term.Environmental groups have lobbied for a ban on certain propellants used in aerosol cans because of the potential damage they can cause to the ozone layer.Finite renewable resources,such as forests and food,must be used wisely.Forestry Companies are required to reforest timberlands in order to protect the soil and to ensure sufficient wood to meet future demand.Because the amount of arable land is fixed and urban areas are constantly encroaching on farmland,food supply can also be a major problem.

自然环境的恶化是全世界面临的一个大问题.在世界上的很多城市里,空气和水的污染已经到了一个非常有害的地步.但关注最多的是由于化石燃料的燃烧而导致大气中温室气体严重超标,以及大气中的臭氧不足和西欧（西欧国家主要指：英国,法国,爱尔兰,荷兰和比利时）国家逐年对水的缺乏.绿色联盟已经有力的迫使公众们采取行动以减少工业污染的排放.在美国,专家已经认识到生态的破坏所产生的后果.并且像塞拉俱乐部和地球之友的监督部门已经采取了行动是人们关注这内问题.
新条例触及某些行业非常困难.钢铁企业和公共设施已投入数十亿美元的污染控制设备和更环保的燃料.汽车行业已引进昂贵的汽车排放控制.肥皂行业不得不提高其产品的生物降解性.
原料短缺的地球原材料包括无限的,有限的可再生和不可再生的有限.无限的.资源,如空气和水,正成为一个问题.水资源短缺已经成为政治问题,以及危险不再是长期的.环保团体游说禁止某些推进剂中使用气雾罐,因为它可能造成的损害可能会导致臭氧层.有限的可再生资源,如森林和食品,必须明智地使用.林业公司必须造林林地,以保护土壤,并确保有足够的木材,以满足未来的需求.由于耕地面积却是固定的和城市地区正在不断蚕食农田,粮食供应也可以是一个主要问题.
