In September, satellite pictures showed more than 20000 fires burning in the Am

11、azon. Experts say most of these fires were set by farmers. The farmers were attempting to clear land to grow crops. The World Wildlife Fund says another serious problem is that too many trees in the Amazon rain forest are being cut down. The World Wildlife Fund says the fires show the need for urgen

12、t international action to protect the worlds rain forests. The group warns that without such action some forests could be lost forever.2. Environmental issues swell to the full in Berlin this week, for the UN spongsored conference on global warming and climate change is the first such meeting since

13、the Rio summit three years ago. With scientists and governments now generally ready to accept that the earth climate is being affected by emissions of CO2 and other greenhouse gases, over a hundred countries are sending delegations. But how much progress has been made implementing the greenhouse gas

14、 reduction target agreed on at Rio? Simon Dary reports.Part II The Earth at risk (I)A.I (Interviewer): Brian Cowles is the producer of a new series of documentaries called The Earth at Risk which can be seen on Channel 4 later this month. Each program deals with a different continent, doesnt it, Bri

15、an?B (Brian Cowles): Thats right. We went to America, both North and South and then we went over to Africa and South-East Asia.I: And what did you find in each of these continents?B: Starting with Africa, our film shows the impact of the population on the environment. Generally speaking, this has ca

16、used the Sahara Desert to expand. Its a bit of a vicious circle we find. People cut down trees for firewood and their domestic animals eat all the available plants and so consequently they have to move south as the Sahara Desert expands further south. I mean, soon the whole of Mali will become a des

17、ert. And in East Africa: here the grasslands are supporting too many animals and the result is, of course, theres no grass nothing for the animals to eat.I: I see. And the next film deals with North America?B: Thats right. In the USA, as you know, intensive agriculture requires a plentiful supply of

18、 rain for these crops to grow, I mean if there isnt enough rain the crops dont grow. And growing crops stabilize soil, without them the top soil just blows away. This is also true for any region that is intensely farmed most of Europe, for example.I: And what did you find in South America?B: In Sout

19、h America (as in Central Africa and Southern Asia) tropical forests are being cut down at an alarming rate. This is done so that people can support themselves by growing food or to create ranches where cattle can be raised to be exported to Europe or America as tinned meat. The problem is that the s

20、oil is so poor that only a couple of harvests are possible before this very thin soil becomes exhausted. And it cant be fed with fertilizers like agricultural land in Europe.For example, in Brazil in 1982 an area of jungle the size of Britain and France combined was destroyed to make way for an iron

21、 ore mine. Huge numbers of trees are being cut down for exports as hardwood to Japan, Europe, USA to make things like luxury furniture. These forests cant be replaced the forest soil is thin and unproductive and in just a few years, a jungle has become a waste land. Tropical forests contain rare pla

22、nts (which we can use for medicines, for example) and animals one animal or plant species becomes extinct every half hour. These forest trees also have worldwide effects. You know, they convert carbon dioxide into oxygen. The consequence of destroying forests is not only that the climate of that reg

23、ion changes (because there is less rainfall) but this change affects the whole world. I mean, over half the worlds rain forest has been cut down this century.Part III The Earth at risk (II)A.I: So, Brian, would you agree that what we generally think of as natural disasters are in fact man-made?B: Ye

24、s, by and large. I mean, obviously not hurricanes or earthquakes, but take flooding, for example. Practically every year, the whole of Bangladesh is flooded and this is getting worse. You know, the cause is that forests have been cut down up in Nepal and India, I mean higher up-river in the Himalaya

25、s. Trees would hold rainfall in their roots, but if theyve been cut down all the rain that falls in the monsoon season flows sraight into the river Ganges and floods the whole country. The reason for flooding in Sudan is the same the forests higher up the Blue Nile in Ethiopia have been destroyed to

26、o.I: Well, this all sounds terribly depressing. Um . What is to be done? I mean, can anything be done, in fact?B: Yes, of course it can. First, the national governments have to be forward-looking and consider the results of their policies in ten or twenty years, not just think as far ahead as the ne

27、xt election. Somehow, all the countries in the world have to work together on an international basis. Secondly, the population has to be controlled in some way: there are too many people trying to live off too little land. Thirdly, we dont need tropical hardwood to make our furniture its a luxury pe

28、ople in the West must do without. Softwoods are just as good, less expensive and can be produced on environment-friendly tree farms, where trees are replaced at the same rate that they are cut down.I: And, presumably, education is important as well. People must be educated to realize the consequence

29、s of their actions?B: Yes, of course.I: Well, thank you, BrianB.I: So, Brian, would you agree that what we generally think of as . er. as er . natural disasters are in fact man-made?B: Yes, by and large . er .

35、ore about the topic: The Effects of Global WarmingThe world is warming up. We know this because average temperatures are the highest since scientists started measuring them 600 years ago. The increase is about 0.2 every year. This may seem very slight, but we know that slight changes in temperature

36、can have a big effect on other things. Most scientists now believe this global warming is due to human activity.Jeff Jenkins is head of Britains Climate Prediction Center. He explains how global warming can happen.Sunlight strikes the earth and warms it up. At the same time heat leaves the earth, bu

37、t part of that is trapped by carbon dioxide and other gases in the earths atmosphere. That has been happening ever since the earth was formed. But the fear is that increasing amounts of carbon dioxide produced by industrial processes and transport and so on will lead to a greater warming of the eart

38、hs surface. So thats the golbal warming that people are concerned about.People are most concerned about the use of fossil fuels. Fossil fuels are oil, coal, wood and so on. When these burn, they produce the gas carbon dioxide. Many scientists agree that an increase in the amount of carbon dioxide an

39、d some of the gases in the atmosphere will increase the amount of warming. Computers are being used to predict what this may mean. They showed that there could be great changes in rainfall and the rise in the sea level as ice caps in the north and south poles melt. This could have a serious effect o

40、n agriculture according to Prof. Martin Perry of University College in London. He says it could become more difficult to grow food in the tropics at lower latitudes nearer to the equator.The most clear pattern emerging is the possibility of reduced potential production in lower latitude regions, and

41、 most generally speaking, increased potential in higher latitude regions. Lower latitude regions are already warm, to put it extremely simply, and plants there are quite near their limits of heat and drought stress. An increase in temperature or reduction in moisture would place limits on crop growt

42、h.Woman: Global warming could reduce food production in lower latitude regions. Lower latitude regions are already warm. Global warming could put more stress on plans and place limits on crop growth.Food production is only one area that could be affected. There could also be health and social proble

43、ms. Prof. Antony MacMichael of the London School of Hygiene and Tropical Medicine believes that some rural areas are already suffering. And the insects and bacteria could spread disease more easily.Already a number of rural populations around the world are suffering from the decline of agricultural

44、systems. Climate change would add to this. And we would expect that it would accelerate the flood of environmental refugees around the world. But it includes not just the food production systems, but the patterns of distribution of insects and infective agents around the world. It includes likely ef

45、fects on patterns of hear-related food poisoning, water contamination and diarrhea diseases, lots of things like this that would respond sensitively to changes in climate.Woman: Global warming could affect the distribution of insects. Global warming could change patterns of heat-related food poisoni

46、ng.Many countries now agree that something must be done to reduce the danger of global warming. But a worldwide agreement on lowering the production of carbon dioxide has been difficult to reach. This is because many economies depend on fossil fuels like oil. Scientists believe its now the politicia

47、ns in every region of the world who need to take action.Part V Do you know?Environment has taken rather a back seat politically since the Earth summit in Rio de Janeiro nearly 5 years ago. But the problems that meeting highlighted had not gone away. One environmental think tank the International Foo

48、d Policy Research Institute has been looking at the future of water and its report reflects growing concern at the huge leap in usage over the past few years.In some parts of the world, water consumption has increased five fold. And the institute, known by its initials IFPRI, says shortages could so

49、on become the trigger for conflict and a major barrier to feeding the worlds growing population. Heres Richard Black of our Science Unit.Its often been said that water rather than oil will be the cause of warfare in the next century. According to the IFPRI report, the time when that happens might no

50、t be far away. The number of people affected by water shortage will increase ten fold over the next 30 years, it says, which could well lead to large scale conflicts.The main reason why water is becoming a scarce resource is agriculture, which now accounts for 70% of water consumption worldwide, 90%

51、 in some developing countries. Countless farmers have switched from growing indigenous crops for the home market to high yield export varieties, which inevitably need far more water. But the IFPRI report says that in some regions water shortage is now the single biggest impediment to feeding the pop

52、ulation. Water scarcity also leads to water pollution. In the Indian State of West Bengal, for example, over extraction of water from bore holes has led to arsenic poisoning which is estimated to have affected two million people so far. But the IFPRI report calls for better water management worldwid

64、oud like to make a donation?Part II Christmas bird countsJohn James Audubon was an American artist in the early 1800s, who illustrated birds in their natural habitats. The Society named after him was founded in the late 1800s by conservationists concerned with the decline of birds, which were being killed so their feathers could be used in the manufacture of womens hats.
