Sustainable management is seen as a practical and economical way of protecting species from dying out. Instead of depending on largely ineffective laws against poaching (偷猎), it gives local people a good economic reason to preserve plants and animals. In Zimbabwe, for instance, there is a sustainable management project to protect elephants. Foreign tourists pay large sums of money to kill these animals for sports. This money is then given to the inhabitants of the area where the hunting takes place. In theory, locals will be encouraged to protect elephants, instead of poaching them because of the economic benefit involved.

This sounds like a sensible strategy, but it remains to be seen whether it will work. With corruption in these developing countries, some observers are skeptical that the money will actually reach the people it is intended for. Others wonder how effective the locals will be at stopping poachers.

There are also questions about whether sustainable management is practical when it comes to protecting forests. In theory, the principle should be the same as with elephants --- allow logging companies to cut down certain number of trees, but not so many as to completely destroy the forest.

Sustainable management of forests requires controls on the number of trees which are cut down, as well as investment in replacing them. Because almost all tropical forests are located in countries which desperately need funds from logging, there are few regulations and motive to do this.

One solution might be to confirm wood comes from sustainably managed forests. In theory, consumers would buy only this wood and so force logging companies to go "green" or go out of business. Unfortunately, unrestricted logging is so much more profitable that wood prices from managed forests would cost up to five times more --- an increase that consumers, no matter how "green", are unlikely to pay.

Which of the following statements is true in understanding the "sustainable management"?

A. Sustainable management is usually used in commercial units.

B. Sustainable management is more powerful than laws.

C. We will probably meet many problems in the course of applying sustainable management.

D. It is likely that sustainable management will replace the laws in protecting living things.

AVERAGE RESOURCES
620 m³water	If we put fresh water and sea water together, we can each have 620 m³ water. But remember, sea water is too salty for us to drink if the factories don’t process it first. So, 620 m³ is little. Saving water in daily use is important.
0.5 hectares of forests	There are 3.869 billion hectares(公顷) of forests on Earth. But we are losing them mainly because we cut trees too much. If we calculate（计算）at the size of a football field, we are losing 343,000 football fields every day, or 1,431 per hour, or 24 per minute!
1.5 centimeters long corals(珊瑚)	All the corals that we have now spread for about 100,000 km in 109 countries. But each of us can only have such a little piece, because seas are getting polluted and corals are dying.
33 stars	According to the latest report, there are 200 billion stars in the Milky Way. Each of us can have 33 of them. Unfortunately, we cannot see most of the 200 billion stars from Earth. We can only see about 6,000 stars. If we don’t use telescopes or we have bad weathers, we can only see about 2,000 stars.
90kg rice	On average, we harvest 0.54 billion tons of rice each year round the world and each of us can have 90 kg. Asia produces and eats 90% of all the rice. How long will it take you to eat up this 90 kg rice?
1 iceberg	Luckily, we still have icebergs to share when Earth gets warmer and warmer. Each of us can have an iceberg of 170m×170m×170m. Up to 10% of Earth surface is covered by ice. There is 31,000,000km³ of ice on Earth in all.

【小题1】On average we each probably have ________ fresh water in the world.

A．over 620m³

B．more than 620m³

C．far less than 620m³

D．only 620m³

【小题2】We are losing the forests on Earth mainly because of________.

A．the man-made damage	B．the climate change
C．the construction of many football fields	D．the environmental pollution

【小题3】When we don’t use telescopes or the weather is bad, we can see ________ stars from Earth.

【小题4】According to the table above, we each can only have _____ because of pollution.

Environmentalists said our planet was doomed to die. Now one man says they are wrong.

"Everyone knows the planet is in bad shape," thundered a magazine article last year. Species are being driven to die out at record rates, and the rivers are so poisonous that fish are floating on the surface, dead.

But there's a growing belief that what everyone takes for granted is wrong: things are actually getting better. A new book is about to overturn our most basic assumptions about the world's environment. Rivers, seas, rain and the atmosphere are all getting cleaner. The total amount of forests in the world is not declining. The Skeptical Environmentalist by Bjorn Lomborg, professor of statistics at the University of Aarhus in Denmark, is an attack on the misleading claims of environmental groups, and the "bad news" culture that makes people believe everything is getting worse.

Now the attacks are increasingly coming from left-wing environmentalists such as Lomborg, a former member of Greenpeace. The accusation is that, although the environment is improving, green groups — with profits of hundreds of mil-lions of pounds a year — are using scare tactics(谋略)to gain donations. Lomborg's book doesn't deny global warming — probably the biggest environmental threat — but destroys almost every other environmental claim with many official statistics.

The Worldwatch Institute claims that "deforestation(沙漠化) has been accelerating over the last 30 years". But Lomborg says that is simply rubbish. Since the dawn of agriculture the world has lost about 20 per cent of its forest cover, but in recent decades the forest area's depleting has come to a stop. According to UN figures, the area of forests has remained almost steady, at about 30 per cent of total land area, since the 1940s. Forests in countries such as the US, the UK and Canada have actually been expanding over the past 40 years. Despite all the warnings the Amazon rainforest has only shrunk by about 15 per cent.

Nor are all our species dying out. Some campaigners claim that 50 per cent of all species will have died out within 50 years. But other studies show only 0.08 per cent of species are dying out each year. Conservation efforts have been successful. Whales are no longer threatened and the bald eagle is off the endangered list.

Environmental groups claim that many of the improvements are the results of the success of their campaigns. Stephen Tindale, director of Greenpeace UK, said, "There are important examples, such as acid rain and ozone, where things aren't as bad as predicted, and that's because behavior has changed."

Restaurant owners should not use disposable chopsticks for the good of their health and the environment , an official of the China Cuisine Association（中国烹饪协会）said.

Bian Jiang, its secretary general, recently called on restaurant owners to say no to one-off tableware(餐具), especially wooden chopsticks. “The country produces and throws away over 45 billion pairs of wooden chopsticks every year, at a cost to the environment of about 25 million tree.” Bian said.

“That’s a heavy blow to the county’s shrinking(正在减少的) forests,” he said, “We should not turn a deaf ear to the call for environmental protection. We should stop using disposable tableware from now on.”

In order to discourage the use of wooden chopsticks and to protect wooden resources, the government put a 5% tax on them in April.

The use of disposable chopsticks has been discussed for years. Their supporters say that both restaurant owners and consumers prefer them, and that an industry has grown up around their production.

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
