Short essay based on a passage and a lecture, TOEFL integrated writing Plz help me correct my article, I'll very appreciate your favor. :) In the reading passage, the author mentioned three possible causes of the Little Ice Age. The professor, however, argued that none of these causes make sense. First, in the reading passage, it is proposed that the Little Ice Age may be caused by the Gulf Stream formed by melted glaciers. By contrast, the professor indicates that the cold stream was not enough to cause the Little Ice Age that it can only effect Europe and North America, however, the Little Ice Age also effected other area such as Africa. Since the Gulf Stream cannot be the cause of the Little Ice Age. Second, the professor refuted the article's idea that the cause of the Little Ice Age may be volcanic eruptions. He states that there were not volcanic eruptions that strong enough to bring the Little Ice Age that time, because if so, there would be other recorded appearances of strong volcanic eruptions but in fact, that are no such records. Finally, the professor challenges the idea mentioned by the reading passage that it was the substantial decreases of human populations that caused the Little Ice Age. He points out that the population of human recovered quickly after decreases in the history, so there was not enough time for this effect to work.
