NASA Satellite- Carli Copell Per.6

NASA Satellite images show most polluted countries in the world

This article is talking about a satellite that NASA has come up with to show us the most polluted countries. Nitrogen Dioxide is a common emission given off by factories and many manufacturing agency's that are found in cities. This creates the  brown haze w see hovering over the city, smog.

Synthesis:
This is a very important topic to bring up. If we keep living like this, and producing more and more pollutants into our world and cutting down trees and plants that provide oxygen for us, we will eventually run out. We cant keep living like this. This can not only relate to the past but to our future. If we don't stop now it will only get worse.
