Let's try our best to protect the environment

Dear friends，

    I'm a student of Grade 9 in Dazhou． My name is Li Hua． As we know， we have only one earth．But in recent years， many disasters happened on the earth and unusual weather appeared very often．Even worse， the novel corona﹣virus broke out nearly all over the world this year．All these bad things were caused by the terrible environment， but the terrible environment was caused by humans．Although our government has made some policies and taken many useful measures to protect the environment in the past few years， there are still many things to do． As students in Dazhou， what should we do？

____________．

    If we all keep doing these things， I believe the environment will be better and better． Let's try our best!
