Back in 2006:
In 2009:
Pollution has always been an issue with Hong Kongers. As you can see my pics above, the difference between 2006 and 2009. And the 2009 photo is on a good day! My cousin got married last year and her photos were beautifully taken (location above), but the haze spoilt it.
Now more than 200 companies are getting support on a petition for cleaner environment. HK is the only place that I noticed a prominent feature in the weather forecast that shows the pollution index, no matter what time of the year it is.
