This is because trees suck up carbon dioxide as they grow, so every time forests are chopped down it reduces the Earth’s ability to absorb the greenhouse gas.
这是因为，树木在生长过程中吸收二氧化碳，因此，每次砍伐森林都会降低地球吸收温室气体的能力。
But since plants absorb carbon dioxide as they grow, crops grown for biofuels should suck up about as much carbon dioxide as comes out of the tailpipes of cars that burn these fuels.
不过，考虑到植物在生长过程中是会吸收二氧化碳的，因而用于制造生物燃料的植物可以抵消一部分由它们作为汽车燃料而释放的二氧化碳。
