The World in the Cloud

This article was written in an era when smog was becoming increasingly serious and garbage classification was not yet common. I learned from some public welfare films, documentaries, films, etc. That our ecological environment is so fragile and needs to be cared for, loved and protected by humans. Just because the earth is the only home for mankind. I would like to use this article to alert people, and hope that you and I can contribute our part to protect the mother of mankind, the earth.
