Dear editor,
Some years ago, my hometown was used to be a beautiful place. Thick trees and grass can be seen all over the hills. As time going by, people destroyed almost the whole forest grow more crops. To make matters worse, people let their cattles eat up the grass. So you can only see wasteland instead green forests now. As a result of, when it rains, the soil is washed down the hills and into the rivers. Strongly winds also blow away the valuable soil lie on the top of the fields.
I do hope all the people will take good care of the forests but plant more trees to improve our living conditions.
