You can focus these conditions of the entire Hong Kong, or focus yourselves on a few areas in Hong Kong, or even compare the conditions in a few selected areas.

Examine what the Government has done in trying to reduce, or at least limit the increase of, this pollution. You are free to examine any other issues related to air pollution in Hong Kong which you think interesting.
