My opinion

About stuff:
This video can help us to understand how the world goes. Because it's very dangerous to the enviroment, and the air that we breath every day. The big problem is the pollution. All that we do in the world pollute, and we have to be careful. This video is to awareness us, and teach so many things to recycle, and save so many resources.

About the girl who silence the world for five minutes:
I think this girl is very brave, and has the value that many people haven't got, to tell the world how are the people, and how we behave with the world. She tell us all the consequences, and all the problems in the world, and this problems affect us too.
