Don’t Rely on Plankton to Save the Planet
Encouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere.(46).
Adding iron to patches of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air.(47).
Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyse how factors such as ocean chemistry and water circulation would affect the process if 160, 000 square kilometres of ocean were seeded with iron for a month.(48).
In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilising the ocean removes 1 million tonnes of carbon from the atmosphere -- just 0.2 per cent of the carbon dioxide humankind spews out each month.
Rough estimates in the past have predicted similarly disappointing results.(49)says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology. "But the take-home message is the same.(50)"
A Its opponents argue, however, that it will stop global warming.
B Its opponents fear that it will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed,
D They found that 100 years later only between 2 and 11 per cent of the extra carbon that was originally taken up by plankton had actually been removed from the atmosphere.
E "These are newer and better models,"
F Ocean fertilisation is not the answer to global warming.
选项
答案
B
解析
本文第一句话说的是,一些人竭力劝说促使海洋浮游生物生长是去除大气中二氧化碳的一种有希望的方法。从“竭力劝说”这个短语中可以推出,不同意这一假设的大有人在。从提供的选项看,只有A和B有可能,因为A和B都提到了这一假设的反对者。A说的是:但是反对这一假设的人争辩说,促使浮游生物生长会阻止全球变暖。B说的是:但是反对这一假设的人担心,促使浮游生物生长会破坏海洋生态系统,并且计算机模型也显示这种办法效果很差。A实际上是同意一些人所做的假设,所以不对。也就是说B才是正确的选项。
