The smog in china has gotten so bad that citizens are wearing masks in the street! I think this is awful and I think that China really should do something about the terrible polluted air. It is so polluted in China that it would be miserable to live there in that smog.
This is the type of thing where I think certain air purifying chemicals should be released into the air to make human's health and work more efficient and to improve the state of the atmosphere and polluted areas
