Hong Kong's pollution has quickly become a major issue for the government. One of their easier opt-outs has been to blame those filthy mainlanders just over the border with their dirty chimney stacks belching out the smoke and soot that has become the bane of Hong Kong's air. One common urban myth is that pollution disappears during the 3 week long mainland holidays for New Year, May and October. The only problem is it turns out that Hong Kong itself is responsible for more than half of its pollution problem.

The government has pledged to deal with this scourge using "practicable measures" and that we should all relax because things are (cough, cough) getting better and "the [Environmental Protection] department reiterated that it has placed air-quality improvement on top of its agenda."

Bear that in mind as you try and pick out the skyline through the muck.
