There are some things we can do to make our classroom a greener place.

Firstly,  

Answer:

To begin with, we must understand the whole concept of "green". So what do I mean by "green"? It doesn't just mean a color, it also means eco-friendliness and cleanness. "Green" reflects the state of being free from rubbish and being unharmful to the environment thanks to having very little litter. Students can help by planting trees, cleaning the school playground, saving electricity, etc. Helping is important, but the will to keep the school clean is even more important. The only way students will help without being forced to is to persuade them, telling them how bad the situation will be when the school isn't green, and how it will affect them. Moving on, if I were the principal of our school, I would try to raise funds for eco-friendly projects. Not only that, I would also organize classes and events where students can learn about Going Green.  Therefore, each and every one of us must play a role in protecting the school's environment. Let's do this together, you and me.
