These undesirable consequences of the expansion of world markets have assumed alarming proportions within a relatively short period of time. China is on course, this year or next, to overtake the United States as the world’s largest CO2 emitter, even though its per capita emissions are only one-fifth or even less of the US level.
这些世界市场扩展带来的不良后果在相对较短的时间里大为增加，令人担忧。即使中国的人均二氧化碳排放水平只是美国的五分之一或者更低，它将会在今年或者明年超越美国成为世界上最大的二氧化碳排放国。如果中国的人均排放量差距缩小到二分之一，世界将会如何？印度则在二氧化碳排放水平上紧随中国。
