After a close watch, it is not difficult to find that human are working together to fight it. Apparently, what the drawing has subtly conveyed is supposed to be given further analysis.
A conclusion could be drawn from the picture: we human should work together to solve the pollution issue. And my words are based upon the following two reasons. On the top of the list is that air pollution has become common in our country and individuals have no enough strength to cope with it. In addition, there is the other point that no one can ignore. It is universally admitted that pollution is the result of neglect of the general public and government, and it has resulted in severe loss in economy.
