Ever wonder how this season’s celebrations affect the environment? Guest blogger Krista Fairles takes an amusing look at this very topic:
The holidays are a wonderful, cheerful time when most people wait for Santa to bring them presents. But I’m not like most people. I spend my time wondering just what the environmental impacts of Santa Claus and his reindeer are, and more importantly, how I can calculate those impacts.
Lately I’ve been particularly curious as to whether Santa’s old sled is a clean green flying machine, or if he should be replacing his 8 reindeer with an environmentally-friendly car.
I should mention that, surprisingly, I was unable to find statistics specific to Santa’s magical flying reindeer, so these calculations use numbers from various sources and may not represent actual pollution caused by Santa and his animals. In other words, don’t plain to the government about the damage Santa is causing the environment based on this article.
Santa’s yearly trip around the globe is 44,000km long, twice the average of a North American driver. If we assume that the magic provides the altitude for this trip, then reindeer power only needs to push Santa’s sled forward. To plete the trip in 12 hours, I estimate they must travel at a speed of about 3100km/h. To travel at this speed, for this length of time, the reindeer need to eat an incredible 980 million calories each!!
So the next question is: how much food is in 980 million calories? Well, if they’re eating corn, they’d need to eat 16,500 lbs each — or 1.6 acres of food. Growing 12.8 acres of corn has its own implications for the environment that we’ll leave for another calculation.
We now need to consider that during the global trip the reindeer are “letting out” some of that corn in the form of methane (甲烷，沼气). A resting cow produces 110 kg of methane per year, so flying reindeer would each let out about 4.8 tons. With methane causing 20 times the global warming damage of CO2, and the altitude increasing that damage by 1000% that another 20 times, we can put Santa’s round-trip emissions at 15,488 tons. This is much more than the 100 tons an environmentally-friendly car would release on the same trip!
Bad Santa.

解析：文章大意：圣诞老人每年旅行44,000公里，那么圣诞老人的驾驶是清洁和绿色的吗？
【小题1】D细节理解题。根据第文章五、六、七段可以知道提及到Distance covered、Calories consumed和Tons of waste let out.，而D项没有提及到。故D正确。
【小题2】B细节理解题。根据第六段的第二句Well, if they’re eating corn, they’d need to eat 16,500 lbs each — or 1.6 acres of food.可以计算出10只驯鹿所需要的谷物。故B正确。
【小题3】C细节理解题。根据文章第七段作者提及到驯鹿排放的沼气可知C项和作者的观点相符合。 故C正确。
【小题4】A推理判断题。全文作者以诙谐的口吻讲述圣诞老人每年44,000公里的旅程所带来的污染，体现了作者对环境的关注。故A正确。
【小题5】A主旨大意题。全文作者以诙谐的口吻讲述圣诞老人每年44,000公里的旅程所带来的污染，怀疑圣诞老人是否是清洁和绿色旅行。 故A正确。
