4、est tropical forest, around the size of western Europe would be safe. Brazil, whose territory includes about two-thirds of the forests has impressively tough laws that, on paper, set most of it aside as a nature reserve and impose stiff penalties for illegal logging. But the latest annual figures fo

5、r deforestation in the Brazilian Amazon, published by the government on Wednesday May 18th, have confirmed a disturbing recent trend: the destruction is accelerating despite all efforts to control it. In 2004 August, more than 26,000 square kilometres(10,000 square miles) of forest were chopped down

6、, an area larger than the American state of New Jersey. The area deforested in the past year was up 6% in 2003, far worse than the Brazilian governments predictions that it would rise by no more than about 2%. It was the second worst year for the destruction of the rainforest since satellite surveys

7、 began. It is reckoned that almost a fifth of the Brazilian part of the forest has now been wiped outs if it were to continue at this rate, it would all be flattened within the next two centuries. Things are hardly any better in those portions of Amazonia that lie in neighboring countries: Ecuador h

8、as lost about half of its forest, mainly due to illegal logging, in the past 30 years. Worse still, tropical forests have been disappearing at an even faster rate elsewhere in the world, such as in Africa. The worlds greatest stores of biodiversity and some of its main suppliers of the oxygen we bre

9、athe are still being chewed up at an alarming rate, despite decades of talk among world leaders and environmentalists about the need to preserve them. As has been seen before in Brazil, the surge in the rate of deforestation is a sign that the countrys economy is booming recently it bas been growing

10、 at an annual rate of around 5%. Most of the timber felled illegally in Amazonia is sold to domestic buyers, in particular to the construction industry in Brazils richer southern states. But the forest is also threatened by the rapid expansion of farming and ranching. In the past year, almost half o

11、f the total deforestation was in the state of Mato Grosso on the forests southern part, where huge areas have been flattened to grow soybeans. Last year Brazil earned about $10 billion from exporting soy products, exceeding its income from coffee and sugar, the countrys traditional export crops. Mat

12、o Grossos governor, Blairo Maggi, is also its soybean king his familys farms are the worlds largest single producer of the crop. The rate at which the forest is being flattened could easily rise further. To boost the regions economic development and make attack on poverty, the government plans to as

13、phalt(铺设沥青 ) and widen the BR-163 highway that slices the forest roughly in half, running from north to south. Though the government has been working with environmental groups and others to try to limit the schemes impact, past experience has shown that improved road access invariably means more int

14、rusion of the forest by loggers, ranchers, farmers, mineral prospectors and others. For much of Brazils recent history, in particular during the countrys 1964-85 military dictatorship, successive governments were obsessed(困扰 ) with populating and “developing“ Amazonia, convinced that otherwise a for

15、eign power might seize it. Large sums were spent building highways to open up the forest and a lot of subsidies were offered to get people to resettle there. However, the huge area of abandoned former forest land alongside previous road schemes show that, in fact, much of the region lacks suitable s

16、oil and climate for agriculture. More recent governments have taken the axe to the worse schemes that encouraged people to destroy the rainforest. Besides Brazils tough conservation laws, there are now countless projects, often backed by multilateral(多边的 ) agencies, to develop sustainable forestry,

17、eco-tourism and other means of providing a living for the regions inhabitants without harming their environment. Mato Grosso state has pioneered the use of satellite-mapping to enforce a law that obliges Amazonians landowners to leave 80% of forested land untouched. Police, environmental inspectors

18、and other state agencies are being pressed to work together more closely to cut down on illegal logging. Nevertheless, the priority of Brazils President Lula da Silva and his government is to cut poverty and they know that the surest way to achieve this is through strong, economic growth. So, as the

19、 BR-163 highway project demonstrates, conservation still comes second to economic development. The many sustainable-forestry schemes are seeking ways to have both instead of having to choose one or the other. But while some are highly promising, taken together they have so far had much less impact t

20、han might have been hoped. Most important of all, the institutions that are supposed to protect Brazils forest the federal and state environmental agencies, national and local police forces and the judicial system are weak, poorly co-ordinated and prone to corruption and influence by illegal loggers

21、 and the farming lobby. The murder earlier this year by hired gunmen of Damthy Stang, an American nun who challenged the loggers and land grabbers, shows how ruthless the forests enemies can be. The forests best hope may lie with Brazilians growing wealth. The countrys steady economic and political

22、advance since its restoration of democracy is leading to the development of a larger and more environmentally conscious middle class, a phenomenon which in richer countries has forced governments to take tougher action to conserve natural resources. Around the world, valuable work is being done to i

23、mprove the understanding of the many “services“ that the earths forests provide from water filtration and flood prevention to fruit and fresh air and to seek to finance their conservation by charging those who benefit from them. In the long term, such movements ought to provide a lifeline for the Am

24、azon forest. But will they come in time? Brazil has already all but lost one of its two original rainforests only slivers remain of the Mata Atlantica, which once covered huge areas along the countrys Atlantic coastline. Its remaining rainforest is still four fifths intact. But, day by day, the chai
