There are three things we can do to improve the environment in our school. First, we should clean up all areas regularly. We can organise clean-up activities at weekends. These actions can keep our environment clean, beautiful, and protect the health of everyone here. Second, we must save resources by ensuring all lights and air conditioners are turned off when leaving the classroom, and by fixing any leaky taps immediately.
