Improve our life and environment

Last Tuesday, I had two reading classes. Our teacher did not show up because he had to attend a conference. He asked another substitute teacher to teach us. The substitute teacher was a very active woman. She asked us to read the chapter 3 of the textbook and to find which topic make you interest in. I was interested in the topic of “Global Releaf comes in all shapes and sizes.” As soon as I saw it I had a thought. It was about that we should concern over our environment problem. I should do something to make a progress to our environment even though I am a student. The simplest thing I can do is to plant trees. Scientist said that planting trees can make the Greenhouse Effect decline and reduce heat-trapping CO2 build-up in the earth’s atmosphere. I hope that either people or I can plant a lot trees to improve our life and environment.
