live a better life.
However, it's a pity that we often see some people drop litter everywhere. Some forget to turn off the lights when leaving a room.
To create a greener city, we can ride or walk to school instead of taking a car. Also, we can plant more trees and flowers. Besides, it's a good idea to separate the rubbish into different groups so that things like bottles and can s can be recycled.
Moreover, it is important for us to live a green life. We should reuse things and watch less TV.
In all, if everyone does his part, we can live a better life in a greener city.
