进入夏季,在人们苦恼于气温“一年更比一年高”时,美国一群科学家又给了人们当头一棒。他们的研究表明:要想阻止气温逐年升高的趋势、化解温室效应的威胁,人类还得另想办法,而不能像从前那样寄厚望于森林。因为森林吸收的大量二氧化碳,最终几乎会如数奉还给地球。温室效应被列为21世纪人类面临 In the summer, when people were troubled by the temperature “a year is even higher than a year,” a group of scientists in the United States gave the people a blow. Their research shows that if we want to stop the rising trend of temperature and resolve the threat of the greenhouse effect, humans have to think differently, and they can’t place high hopes on the forest like before. Because the forest absorbs a lot of carbon dioxide, it will eventually be given back to the earth in almost every amount. The greenhouse effect is listed as a human face in the 21st century
