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. Second, we should plant more trees and flowers around the school. This will make the school greener and create a pleasant atmosphere for students. Third, we can reduce plastic waste by using reusable bottles and lunch boxes instead of single-use plastic ones. In conclusion, we can improve the environment in our school in many ways and even small actions can make a big difference.
