Answer:
Dear Principal,
We have been informed to give suggestions to make our school more environmentally friendly. I am very happy to share my simple ideas. This will make our campus more alive and natural.
To begin with the help of Love Green Club, we can plant many trees inside and outside school. It will create a habit of planting trees and protecting them. Moreover, our school ground will become attractive.
Secondly, I would like to invite your attention to a very serious environmental problem happening in our school. Most of the students are bringing their lunch box and snacks in plastic carry bags . Even though they are bringing it for 30 minutes use ; it will remain in our campus for thousand years . I think that , with the help of our Love green club members, we can make paper bags using old newspapers . So plastic carry bags can be replaced by paper bags made by our school students. Therefore, we can ban plastic and make our campus GREEN
I hope you will consider my suggestions to make our school eco friendly
Yours truly
(Your name)
