“限塑令”实施三年以来，全国主要商品零售场所塑料购物袋使用量减少240亿个以上，相当于节约石油360万吨，折合标准煤炭500多万吨，减少二氧化碳排放1000多万吨，全国“白色污染”问题得到一定程度缓解。 如果下列各项为真，哪项最能质疑上述结论？（）
A.
最近三年以来，全国工业的煤炭使用量增加了267％
B.
最近三年以来，全国的二氧化碳排放总量呈现递增趋势
C.
“限塑令”再实施三年，“白色污染”的问题将得到极大缓解
D.
付费购物袋用量虽减少，但商场免费的食品塑料包装袋使用量大增

It’s generally agreed that the greatest threat facing the world today is the warming of the earth’s atmosphere, commonly called global warming or the greenhouse effect. But what is the cause of the greenhouse effect
B.
We have been producing too many of the gases which, when they are released into the earth’s atmosphere, trap heat, and thus raise their temperatures. There are several gases involved, but the main ones are carbon dioxide (二氧化碳) and chlorofluorocarbons (氯氟甲烷)--often called CFCs. The carbon dioxide comes from burning forests and from bunting fossil fuels such as oil and coal. The CFCs are given off by refrigerators and air-conditioning systems. Carbon dioxide is to blame for 56% of the greenhouse effect, and CFCs for 23%.
C.
The global warming we are experiencing now is only a result of the carbon dioxide and other gases we have dumped into the atmosphere up to the 1960s. In other words, the damage may have already been done. Temperatures are expected to increase by at least 1.3 Celsius degrees by 2030 and 3 degrees by the year 2070.
