Dear Principal!

I am a lucky student to study at the school where you are working, I boldly wrote this letter to you.

Currently, through the newspapers and other websites, I know that the global climate is increasingly changing in a negative way. These changes have a devastating impact on people's lives. Floods, earthquakes, tsunamis, droughts, mangroves... It makes people suffer. And I also know that, to prevent that, we need everyone's help.

Although I and the others are young, I have not done great things, but I believe that as long as we unite, we can still do something for the beloved earth. However, in order to unite everyone together, a leader is needed. For me, no one else can be more suitable than you. Because you are our honorable teacher.
