Ever since they were first put on the market in the early 1990s, gentically mondified (GM, 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr?
Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact
Studies show that the most crown GM croo.
GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production.
Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. " The promise was that you could use less chemicals and boost production. But nether is true," said Bill Christison, President of the US National Farm Coalition.
At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.
As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which "green" farming is supposed to be the first choice.

Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The “eco-guilt” brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.
Perhaps that explain why a new book by Bjorn Lomborg received so much publicity. That book, The Skeptical Environmentalist, declares that it measures the “real state of the world” as fine. Of course, another explanation is the deep pockets some big businesses with special interests. Indeed, Mr. Lomborg’s views are similar to those of some Industry-funded organizations, which start huge activities though the media to confuse the public about issues like global warming.
So it was strange to see Mr. Lomborg’s book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that “After Lomborg, the environmental movement will begin to die down.”
Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg’s “preference for unexamined materials is incredible (不可信的)”。
A critical (批判的) eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blind before a world partially exhibited by the media. That’s a shame, because matters concerning the health of the planet are far too important to be treated lightly.
According to the passage, which of the following may be regarded as “skeptics”?

A．People who agree on the popularity of “eco-guilt”.

B．People who disbelieve the serious situation of our planet.

C．People who dislike the harmful effect of human activities.

D．People who spread comforting news to protect our environment.

Which of the following can be a reason for the popularity of Lomborg’s books?

A．Some big businesses intend to protect their own interests.

B．The book challenges views about the fine state of the world.
