This is Scientific American’s 60 second science. I’m Karen Hopkin. This’ll just take a minute.

Seems like every other week brings news that a global warming is gonna be bad for some poor animal or other. But plants, well, I guess everyone’s thinking the plants will welcome the heat. I mean global warming is caused by greenhouse gases in plants living greenhouses. So everyone is happy. Well according to a new study published in the February 12th issue of Proceedings of National Academy of Sciences, I was wrong or at least not quite right. Because plants too are likely to face problems that the earth heats up and the biggest problem may be insects. Scientists are looking at the fossilized remains of leafs that fell off trees about 55 million years ago. At that time, the plant was undergoing a period of warming. The scientists found that as temperatures rose, the leaves look more nibble. Seems with more CO2 in the atmosphere, plants take up more carbon that actually makes the leaves less nutritious for plant * bugs. So the insects just eat more. So what * plant will be homes to some hungry bugs which I dare say will not please the trees or anyone else who relies on plants for food which includes ultimately all of us.

Thanks for the minute, for Scientific American’s 60 second science. I’m Karen Hopkin.
我真心希望能获得守护她的力量
怀着这份心意
我一直静静的凝视着窗外的风景
