Advice on protecting the environment

Dear teacher, dear classmate:

Hello everyone! I am a national junior in the sixth grade of my school and have lived on this beautiful campus for six years. The campus we live in is really beautiful. The sky is blue and bright, the flowers are splendid and aromatic, the trees are lush and tall, and the pavilions are exquisite and elegant. But do you know? In other places, the river is not so crystal clear, the sky is not so blue and bright, the flowers are not so bright and aromatic, the trees are not so lush and tall... Our great mother - the mother of the earth is suffering from persecution, human beings are beautiful The home is about to be broken.

In other places, it is often possible to hear the sound of a saw pulling a tree, often smelling the stench of a dirty stream, and often seeing the sight of the yellow sand. The river is polluted, emitting unpleasant smells, floating some garbage; trees are being felled, bare land is exposed, and the birds are lost to the warm home; there are also some littering, plastic bags The phenomenon of flying can be seen everywhere... These phenomena can be seen everywhere, and the Earth Mother is no longer as beautiful as it used to be.
