Last week we had a free time because of our teacher’s illness and we decided to do something good for the school. So, we started to clean-up our school's outdoor campus. We were disgusted with the amount of pollution we found scattered around our school. Then, we thought that we must do something to make our efforts noticeable to the rest of the student. We arranged to pick up trash during lunch and after school. At both times the outdoor campus is used and we put the trash on display so the whole school could see the garbage collage they created. This was only a small-scale study we did to clean our environment. But, we must struggle to preserve and clean up the environment throughout the world. I think there are three major steps we can do to clean up the environment.
