There are three things we can do to improve the environment in our school. First, we should clean up all areas regularly. For example, we can organise clean-up activities at weekends. By doing this, we can keep our environment clean, beautiful, and safe for everyone. Secondly, we should plant more trees and flowers in the school garden to provide shade and fresh air. Thirdly, we ought to reduce plastic waste by encouraging students to use reusable bottles and recycling bins. In conclusion, we can improve the environment in our school in many ways and even small actions can make a big difference.
