It turns out we're also to blame

The common belief in HK is that the 'lion's share' of our pollution problems come from Guangdong province where the factories of the world are located about 50-100km away.

However, recent studies show that this isn't entirely true. At certain times of the year, wind patterns don't push the polluted air from Guangdong down here and HK generates plenty of pollution from marine, automobile and power plant emissions .
