Dear friends,
Do you want to live in a beautiful world? So it is our duty to protect the environment. To reach this goal,
we should keep the following in mind.
First, walking to school is a good way to reduce pollution. Second, we should plant trees every spring to
protect the earth from being washed away. It's also important to reuse everything useful, we should keep our
school clean by picking up and litter. Remember to turn off the taps after doing washing and turn off the lights
when leave the classroom.
Let's take action to protect our mother-the earth.
Thank you!
