Dear Mr. Earth,

     I am so sorry that we make so many pollutions in your body. So, we are going to reduce it. 

     First, it is air pollution. In Hong Kong, the air pollution is very serious.  The air in Hong Kong is very dirty, so we always cough in the streets.  So, now we suggest some solution to reduce the pollution.  We can stop the car engine when we are waiting in the car.  As if the car engine stops, the car will not emit exhausted gas.  Or we can take more public transport to reduce the exhausted gas.

     Second, it is rubbish. In Hong Kong, people make over 5 million tons of rubbish.  Now you know that how serious of the rubbish in Hong Kong is.  So, we must do something to remedy it.  We can take our own bag when we go shopping because we can use less plastic paper.  Then, we can use more recycling bins.  In Hong Kong, we can recycle many things such as, paper, bottles and also can. 

     After that, you can be healthier and also we can live better.
