How horrifying. Whether it’s the Xmas factory overtime in China, or some unfortunate winds/temperature combinations, Hong Kong’s pollution is a topic that this city should hang its head in shame about. How embarrassing to have air this bad when one is situated on a waterfront. Appalling and inexcusable. Get your act together HK government and pass more acts to outlaw unnecessary pollution! Make it law for all factories to clean up their emissions, at their own costs. No wonder people are going to Singapore to breathe easy. What kind of a city thinks it’s acceptable to so heavily defecate in its own living space? One that doesn’t understand the amazing marketing potential of clean air perhaps?
