This article is interesting because we can read about thins that happen in the world and that are very interesting, but I will talk about the third one because is the most interesting.
3. The Plague of Justinian
Is amazing learn about a plague that kill like 200 million people and caused by the bacterium Yersinia pestis.
I think the some times the bacterium are in mutation so this can kill many people or can mutate in the human body.
The swam flu is other virus that surprise me and I talk with some Mexicans that said that this virus was created by the humans so is so confusing to understand this types of virus an situations because now all the catastrophes are really bad and some people said that they have proofs that human provoke this catastrophes but only God know what is happening because in all the times are catastrophes in the past in the present and in the future.
