Our school looks so dirty these days. And it's time to save our school before iy's too late. There are many ways of protecting the environment at our school. Firstly, we should reduce and reuse bottles, cans and plastic bags because they are hard to destroy. If we do so we can save energy and even make more money from selling those things. Secondly, we shouldn't throw trash on the school ground because it isn't only polluted but also harmful to our health and make us get sick. Thirdly, we should make sure our lunch table is clean before we leave. Don't leave milk cartons, napkins ir pieces of food on our table. Push in our chairs as we leave the table and remember to check the floor to make sure we didn't drop anything. Finally, we should go to school by bike, on foot, or public transport to reduce exhaust fumes and save energy. In conclusion, reducing pollution at our school means that we are improving the quality of our study time.
