Planting Trees for the Earth
Dear fellow students,
Trees are important. Trees can take carbon dioxide and other harmful gases from the air and release oxygen into the air.They can cool the air and make our cities less noisy. They can keep the water and stop the soil from being washed away. Trees can prevent the climate from getting warmer and warmer. They can keep the balance of nature. Without trees,humans and animals would die. So we must plant more trees and take good care of them.
    In order to protect our environment, our school is planning an activity “Planting Trees for the Earth”. Let’s join in the activity together.
    That’s all. Thank you.
