China Haze

I was looking at the news and saw a picture of smog in Beijing.  I remember those days.  They say it's from coal burning.  Most people in the north burn coal for heat.  It's too bad for the health of the people though.  I wonder what kind of birth defects that could cause.  When I lived in California, they used to have smog warnings.  It was not like the haze Beijing has.  When you would breath in on those heavy smog days, your lungs would hurt.  You could not take deep breaths.  Maybe the government will eventually change things, but it will take time.
