文章大意:本文是一篇说明文。文章讲述了秦岭大熊猫的食物来源——竹子受到威胁。由于气候变暖,到21世纪末,秦岭的大部分竹子也许会遭遇灭顶之灾。研究者们呼吁全世界采取措施对其进行保护。
1 . The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food — bamboo, which makes up 99% of their meals.
Adult pandas spend most of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of the rising temperature worldwide.
A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate change. “80% to 100% of the bamboo would be gone if the average temperature increases 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report's authors.
He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in The Paris Agreement. But you know what is happening around the world.”
In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger nature reserves.
“But it is far from being enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,”said Shirley Martin from the WWF but not a member of the team.
There are 345 wild pandas in the Qinling Mountains. That is about 18.5% of the population of China's wild pandas. In addition, about 375 pandas are living in research centers and zoos in China.
