One possible version:
Dear Mary,
I am very happy to visit my hometown recently, which I have been away from for more than ten years. It used to be a small town with trees all around. There was no tall building and the streets were narrow. Just out side the town there was a river. You can see different kinds of fish swimming in the clear water. People here lived a simple life.
Great changes have taken place here these years. You can see tall buildings, a department store and a few factories. Different kinds of cars and buses are running in the big streets. But with the development of the industry, we have fewer trees. Air and water pollution is becoming more and more serious. I think something must be done to stop pollution and make my hometown more beautiful.
Best wishes
Tom
