More wood was removed from forests in 2005 than ever before, one of many troubling environmental signs highlighted on Thursday in the Worldwatch Institute’s annual check of the planet’s health.
The Washington-based think tank’s "Vital Signs 2007-2008" report points to global patterns ranging from rising meat consumption to Asian economic growth it says are linked to the broader problem of climate change.
"I think climate change is the most urgent challenge we have ever faced," said Erik Assadourian, director of the Vital Signs project. "You see many trends in climate change, whether we are talking about grain production which is affected by droughts and flooding, or meat production as livestock production makes up about 20 percent of greenhouse gas emissions," he told reporters in a telephone interview before the report’s release.
Assadourian said the key message of the report was that unsustainable consumption patterns were responsible for climate change linked to carbon emissions and other ecological woes. He said of the 44 trends tracked by the report, 28 were "pronouncedly bad" and only six were positive. The trends range from the spread of avian flu to the rise of carbon emissions to the number of violent conflicts. The growing use of wind power is among the few trends seen as positive.
Some of the points highlighted in the report include:
--Meat production hit a record 276 million metric tons (43 kilograms or 95 pounds per person) in 2006.
--Meat consumption is one of several factors driving rising soybean demand. Rapid expansion of soybean plantations in South America could displace 22 million hectares (54 million acres) of tropical forest and savanna (热带大草原) in the next 20 years.
--The rise in global seafood consumption comes as many fish species become scarcer. In 2004, people ate 156 million metric tons of seafood, the equivalent of three times as much seafood per person as in 1950.
Other analysts and think tanks have focused on different trends they say mean less cause for alarm. For example, they point out that while more wood is being removed from forests on a global scale, many parts of Europe and North America have experienced reforestation in recent decades. [br] In South America, in the next 20 years 22 million hectares of tropical forest and savanna will be displaced by______.
选项
答案
rapid expansion of soybean plantations
解析
同义转述题。本题提问的是在南美洲,是什么导致未来20年热带森林和热带草原面积减少2 200万公顷。该要点意思是:在南美洲,由于肉类需求的增长,大豆种植面积相应扩大,这可能会导致未来20年热带森林和热带草原面积减少2 200万公顷。题干是将原句变为被动语态,原句中rapid expansion of soybean plantations作主语的成分,在此题中变为displaced by的宾语。
