Passage FourThe atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E. O. Wilson, a biologist at Harvard, calls the depletion(枯竭、耗尽)of rain forest areas "the greatest extinction since the end of the age of dinosaurs(恐龙)."Unlike some environmental issues, rain forests' depletion has fortunately received significant public and media's attention. Despite the opposition to the cutting down of rain forests, the problem continues. Every year, Brazil chops down an area of forests the size of the state of Nebraska. In addition to the Amazon's rain forests, many other forests are being cut down as well.: In Indonesia, Zaire, Papua-new Guinea, Malaysia, Burme, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain forests that were once great have been lost.According to some estimates, 50 million acres of rain forest are cut down every year. The United Nations says the figure is closer to 17 million acres. The World Wildlife Fund says that every minute,25 to 50 acres are cut down or burnt to the ground.The world's growing population has been a primary reason of rain forests' destruction. More people need land to live on and wood products to consume. Limiting population growth may be the first in a series of steps that would alleviate the destruction of the rain forests.48. In the opinion of the author, ______are being destroyed terribly at present.A. the oceansB. the atmosphereC. the rain forestsD. all the above

The makers of Europe's toilet paper and other household paper goods are contributing todeforestation by failing to offer consumers enough recycled products, conservationists said recently.
"Everyday about 270,000 trees are effectively flushed down the toilet or end up as garbagearound the world; such a use of the forests is both wasteful and unnecessary," said Duncan Poundof WWF, formerly known as the World Wildlife Fund.
According to a WWF study, the five biggest manufacturers of disposable paper products inEurope are Procter and Gamble, SCA, Kimberly Clark, Mesa Tissue and Georgia Pacific, whichcontrolabout 70 percent of European market. The vast majorityof their products contain"alarmingly low levels" of recycled fibers, it said.
That means that"virgin fibers" extracted from natural forests and tree plantations around theworld"end up as waste without the consumer's knowledge, ” the Switzerland-based internationalconservation group said in this communique.
"Consumers have no idea that they may be threatening the world's forests when they go to thebathroom, "said Pollard, who heads the WWF program on European forests.
"The manufactures claim that retailers mainly want non-recycled products because that is whatconsumers choose." the WWF said.
"It's a myth that recycled tissue products are not of good quality." Pollard said.
The European tissue business is worth around 8.5 billion euros(10 billion dollars) annuallyand accounts for 26 percent of global consumption.
Each European uses on average 13 kilos of paper products per year, the WWF said.
The WWF has asked the companies to better inform consumers about how much of theirhousehold paper goods are made with recycled fibers and to advise them to buy bounds of recycledtoilet paper and tissues.
What does the underlined part"end up as waste without the consumer's knowledge" mean ?__________A.Consumers waste "virgin fibers" because they lack knowledge
B.Consumers don't waste "virgin fibers" without knowledge
C.Consumers stopped using "virgin fibers" as waste because of knowledge
D.Consumers waste "virgin fibers" without know it
