关于北京雾霾的英语作文.几十个词就行.

One possible version:
Dear Mike,
Thank you very much for your concern.Last months several places in Beijing were blanketed with thick yellow fog.Everything around disappeared from oursight.Some highways were closed.Traffic jams were commonly seen in the streets.Many people,especially children and seniors,even found it difficult to breathe.As a result,local hospitals were crowded with people who had problems with their noses and lungs.Part of the cause was the dry weather,but the severely damaged environment contributed a lot to this nightmare.Personally I didn’t get any health problems in the haze because I stayed mostly indoors.But to make a significant change we really have to do more to protect our environment.To live a better life we have to push on with the economy,but it wound be meaningless if we have to achieve it at the cost of our breathing air.Regards!
Yours,
Li Hua
