In the beginning, I have no idea about what’s PM2.5.  
I only hear of PH or Project Manager.
And then, I surfed Internet to get some news about PM2.5 and just got the point.
PM means Particulate Matter (PM).
That is one of serious pollutants, and the most important in terms of adverse effects on human health.
WHO suggest that PM2.5 levels should below ten micrograms are safe.
In Europe, they really attaches importance to environmental awareness.
They make so many standard rules to control pollutions extending.

Two years ago, I had a business trip in Shandong of China.
When I ready came back home from the employee’s apartment to the airport by a car, I saw a heavy fog on the air.
However the weather was fine, and the sunshine was so bright.
I remembered that it was about nine o’clock on Sunday morning.
I still could see some kind of things like clouds filled with the sky.  
I was not sure that’s fog or not in the moment.
As I know, fog always has in very early morning or other place, such as mountains or country sides.
I have never seen fog filled bright sunshine.
Then I came back to Taiwan, suddenly, I just totally understood that!
That things what I ever saw in China is an serious air pollution, not nature fog.
Nowadays, the rapid development of China industry become more and more complex.
China industry causes air pollution getting worse.
But bosses and workers of China have other things on their minds, like getting a better job, a higher salary and earn more money.
People always realize that it's a dangerous things when they faced the death or they couldn't live here anymore.

I have saw someone’s comment for PM2.5 in the Internet. Of cause, He is a Chinese.
According to his point:
1. The Western want to keep their advantage, so they make rules and ask China having to follow their rules.
2. In US, drug related and obesity issues have killed much more humans than the alleged food poisoning and pollutions caused deaths in China. However it is ironical that the US press pay a great deal more attention to the alleged Chinese problems than to their own concrete problems.

I think it’s still a long way in China to improve their environmental awareness.
