Conclusion

 

A bathroom with no brown paper towels crumpled into a ball.

A bathroom with a sound of air-blowing.

A bathroom with no cost of disposing rubbish.

It sounds like small matter to start with changing from a bathroom,

but it is a first and important step toward wasted paper-free campus

and also toward saving poor trees.

Now you are in a trade-off between convenience and environment.

I hope you have already seen a right choice for trees, for the Earth and for our future.
