I think it is an important step, clearly for presenting complaints, the problem will not be solved; we should all do it if we see something of this kind. In addition to the complaints, there are many steps to follow, such as organizing protests, taking care of daily consumption or becoming aware that a sustainable life is better for everyone.
I personally do not think that filing complaints will help reduce air pollution because officials are already aware of the problem. Doing so, will do nothing in aiding the problem. Unless people are able to make officials aware of unknown issues, filing complaints will not help
Yes, filing complaints in one way might help reduce pollution but it won't completely eliminate it. I think by filing complaints, it does give the issue precendence in coming to the top so people become more aware by it, but along wiht complaining people need to take action and come up with plans to resolve the complaints.
