Light pollution now has become a big problem and led to much waste in our society. It has been estimated that 30% of the electricity generated for outdoor illumination is wasted. Important, too, are the environmental costs of producing the energy to power wasted light. For example, for every kilowatt-hour of electricity used, almost two pounds of carbon dioxide and almost two grams of sulphur dioxide are emitted into the environment. (46)
Thus by simply eliminating wasted light, those amounts can be substantially reduced with no negative effect on necessary lighting and with decidedly positive environmental benefits for the region.
For individuals and families another significant issue is that of light intrusion, the spilling of un-wanted light onto private property. This concern is already addressed in some local zoning codes where maximum light levels at property lines are established. (47)
But as the problem becomes more common, homeowners may also sense that the intrusion of unwanted light keeps them from u-sing their outside property at night as they wish or may even interfere with indoor activities by shining into the house interior.
Indeed, legal proceedings could result from such unwanted intrusion as a violation of property rights. Furthermore, poor quality lighting, whether commercial, municipal, or residential, can lessen the appeal of a neighborhood, lowering property values if the area begins to look too bright and gaudy.
Yet the problem of light pollution is easily remedied. In general, good lighting uses only the amount of light necessary, for a specific purpose, and that light is directed properly. (48)
Lights allowing no illumination above the horizontal plane of fixed objects and mounted at the proper height to do their job while avoiding glare and light intrusion are the ideal.
In recent years, there has been a conscious effort by many municipalities, businesses, and individuals to better address the ways lighting is used.
So the next time you are out at night, make a note of the way things are lit. (49)
Remember, regardless of how we achieve the goal of reducing light pollution, the simple fact remains that we all win when sensible lighting is used.
Good lighting saves energy and money, it reduces pollution, it improves the appearance of neighborhoods and maintains property values, it enhances the scientific and aesthetic appreciation of the glories of the night sky, and it preserves that beauty and inspiration for us and for our children. (50)
So when you find yourself lucky enough to be in a place where it is still dark enough to see the sky sparkling with stars, think how much less beauty there would be in the world without it!
And become an advocate for sensible and efficient lighting.
选项
答案
但是随着这一问题变得更为普遍,房屋拥有者也可能感觉到,讨厌的光侵入使他们不能如愿地在夜间使用户外财产,或光照入室内甚至会干扰了室内活动。
解析
本句是复合句,句子主干结构为homeowners may sense that…。句中as the problem becomes more common是状语从句;that the intrusion of unwanted light keeps them from…by shining into the house interior是宾语从句,该部分中as they wish是状语从句;介词短语by shining into the house interior作状语。翻译时注意添加词汇,将语义补充完整。may even interfere with indoor activities前省略了主语the intrusion of unwanted light,翻译时将"光照入"添加,使得语义更清楚、准确,句意更通顺。
