Heavy Smog in China
The winter in 2013 impressed people not for its extreme coldness but the heavy smog hung over 25 provinces. It caused great disturbance to daily life.
Obviously, smog comes from pollution. Many factories let the smoke into the air without any filtering process. Day by day, it is no wonder that smoke, dirt, and dust accummulate in the air and finally turn into dense smog.
How can we curb smog then? Levying heavy penalty on those irresponsible factories is definitely a must-do. Before the air is once again purified, we should also take some actions to protect ourselves such as wearing a mask and reducing exposure outdoors.
We should all try our best to contribute to a cleaner environment for mutual survival and easier life.
