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 1,000% 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.
