So, I know this is nothing new to create a character with a gas mask, but I needed to do a work vector to one of my classes, so I decided to do it ... and it turned into something much more serious.

His name is Noah (that name came immediately to my mind, because I think a strong name Noah. And in the world where he lives, you must be strong).
He lives in a world where humanity could stop global warming, but unfortunately a major chemical disaster happened, and spread in the air causing damage in some people.
Now there are two types of human beings on earth ... infected humans who need to use these masks to breathe (and others problems) and the humans who have managed to adapt.

The story is a little longer and more complex than that, but I will not write everything here, because I've written too much.
And if you made ​​it this far, then you have my respect! You are a survivor of my terrible English.
