    Even in this electronic era, paper continues to play a complete role in our daily lives. Americans depend on about 85 million tons of paper and paperboard a year to help us clean, organize, advertise, educate and much more, according to the Environmental Protection Agency.
    Unfortunately, this soft product comes with environmental disadvantages. These include the loss of biological variety associated with permanent forest; an energy and water intensive production process that generates greenhouse gases and other dangerous products; and a life cycle that ends in a landfill or incinerator nearly half the time.
    Of course, we have choices. We can lessen paper’s environmental blow first and foremost by reducing our dependence (using cloth towels in the kitchen, printing on both sides of the sheet at the office, etc.). And, when we really need to use paper, we can make better-educated buying decisions. Here are a few tips for purchasing eco-friendly paper:
    Buy recycled. Doing so saves landfill space, supports green jobs and " reduces the total amount of resources you’re using", says Susan Kinchella, executive director of Conse-rvatree, an organization that advocates using more paper which can be used again.     Study labeling carefully. Look for products that contain post-consumer waste (or material that has completed a full life cycle); the higher the percentage, the better. A chasing-arrows symbol may simply mean a paper product can be recycled, while the word" recycled may refer to only a small percentage of recovered fibers.
    Demand certificate. A number of organizations certify that the original fiber used in a given paper comes from responsibly managed forests. Kinsella says the one environmentalists trust most is the Forest Stewardship Council. Check with your printer or paper supplier to see whether it carries FSC-certified lines.
    Consider tree-free options. Some paper is now made from agricultural crops, several of which have a higher yield per acre than some types of trees used in papermaking and may have other benefits. Tree-free material is available for personal use (think cards and invites), but before buying, investigate its origins and the farming practices used. For a list of suppliers, check out http://www, con-servatree. org/tree free. html.
    Check color. Paper which is made whiter without the use of CI or other chemicals is less polluting. Using paper without CI is another step up. And when using a professional printer, ask for vegetable-based inks.
What is the disadvantage of paper made from trees?

选项 A、It is too soft to bring environmental disadvantages.
B、Many species are disappearing due to the reduction of forest.
C、The greenhouse gas and other products waste much water and energy.
D、Some kinds of lives are buried under the earth or fired to death.

答案B

解析 事实细节题。由题干中the disadvantage of paper定位到第二段可知,纸张的危害有很多,例如会造成物种数量的减少,消耗大量的能源和水资源,并且产生温室气体以及其他一些有害的副产品,还会造成大量资源生命周期缩短,最后被掩埋或焚烧等。故[B]“由于森林的减少,许多物种正在消失”与文章意思相符。[A]“纸张太柔软了,不能造成任何环境问题”,本段第一句说明,尽管纸张柔软,但是却能带来严重的环境问题,故排除;[C]“温室气体和副产品浪费了许多能源和水资源”,文中只是阐述了生产纸张会消耗大量水资源和能源,也会产生温室气体和副产品,但并未提到资源浪费和温室气体与副产品之间的关系,故排除;[D]“许多生命被埋在了地下或者被焚烧至死”,文中所说被掩埋和焚烧的是资源的使用周期而非真正的生命,故排除。
