Care for the classroom environment proposal

All the classmates of the six classes:
In recent months, I have found that the garbage on the ground in the classroom outside our classroom and in the classroom is everywhere, mostly with some scraps of paper and some discarded garbage. Most of us usually turn a blind eye, so these little garbage will become everywhere.
These small garbage are produced by our usual lack of attention to health work. When the students cut the paper in the art class, the scraps of paper fell on the ground, and the students used them as air. They didn't pick it up and threw it into the trash can. Some of the values ​​were too rough, "brushing" After a few moments, I swept the ground. Particularly serious is that the wrapper of the straw is also everywhere. When the students drink milk, they throw the wrapper of the straw into the ground and simply refuse to take a few more steps and throw it into the trash. There is also a pen cover for the pen. When the students write, they put the pen cover on the table. When the hand accidentally hits it, the pen cover falls to the ground and then “I don’t know where to go”.
This kind of lack of care for the classroom and the outdoor environment shows that we have not developed good hygiene habits. We should take care of the environment inside and outside the classroom, don't throw paper scraps, don't throw the straws of the straws, put the pen cover, and don't let the pen cover "I don't know where to go." We should see the garbage and pick it up. Classmates, let us care for the environment inside the classroom and outside the classroom just as we care for our home!
