What is the greatest human disaster?

It is the disasters that occurs in America. It is the disaster that occur where the big western medias are. That is how I see it really.

Look at Beslan hostage situation. I can tell you that is like orse than the Twin Towers in some ways or maybe even equivalent because it was just school children.

WTC tragedy as much as it is big was way over dramatized. I remember some stations were even playing dramatic music while giving their report in it.

 1. a. Of persons: Ignorant of letters or literature; without book-learning or education; unlettered, unlearned; spec. (in reference to census returns, voting by ballot papers, etc.) unable to read, i.e. totally illiterate. Also, more generally, characterized by ignorance or lack of learning or subtlety (in any sphere of activity).

To call someone illiterate isn't to specify that they cannot read, only that they do not read. The previous poster was clearly unread, and you, apparently, need to peruse a dictionary sometime.
