Do you know that Rudolph the Red-Nosed Reindeer was NOT originally part of Santa’s reindeer team? In the 1823 poem "A Visit from St. Nicholas" (commonly called "The Night Before Christmas"), Santa Claus's team of flying reindeer numbered 8 and the names of the reindeer are Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, and Blitzen. Rudolph was included in the 20th-century due to the enduring popularity of the Christmas song "Rudolph the Red-Nosed Reindeer".
Well, in a few years’ time, Santa may need to replace Rudolph and gang because global warming has curbed winter food for the animals and scientists has found that reindeers are getting smaller and smaller as a result. According to their reports, the average weight of adult reindeer on Svalbard, a chain of islands north of Norway, was 55kg in the 1990s. Now it’s 48kg.
Since global warming is not going to stop any time soon, chances are the reindeers will get smaller and smaller in the future. Considering how fat Santa is and how heavy all the presents are, chances are Santa need a new animal to pull his sled. Polar Bears maybe? No, wait; polar bears are in trouble too due to global warming so…machines?
