Well, before you even continue, please get in your heads that I ain't evoking any terrorist, religious, anarchism or any other negetive feelings which harms anyone's interest, whatever. Be warned!

In secondary two, we study DOOMSDAY geography. On the contary, I beg to differ, how wrong. Many people thought that global warming would wipe out humanity, and bring forth the end of the world. No, global warming would actually call upon the Ice Age. Think, the melting of polar icecaps and motion of tectonic plates would intervene with the ocean and wind currents, and then leading to climate change and CHEERIO, you get your glacier epoch! Err... before you can beat the drums and start your fete, begin to vituperate on how you're gonna die in the perennial jack frost.

PS:

-Or probably, Toba would blast its vent, and send the blizzards for eternity!
-I ain't censuring Sec2 geography, I just have a rancour of memorising the facts.
