Trevor, I'm sure you are right. Cross the border and it gets soooo much worse. But unless you can explain that to all the tourists who go up to the peak to peer at the haze, it will always appear to be HK's problem. And I think it will take a lot more than just talk to fix it.
As new technology, LNG, clean power etc., gradually takes over, especially around the Pearl River Delta area, maybe we will start to see some daylight (pardon the pun).
Hope so, I'll be back in HK next month, and a clear day would be nice. But I'm sure it will be clearer than Shanghai and Beijing - I'll let you know!
