Now the earth is in bad condition. In some places, air and water pollution is so seriously that it causes many deaths. At the same time, many animals are in danger because of their habitats are being destroying. Lucky, we human beings have realized the problem. In April 22nd, million of people throughout the world do something well for the earth. Some clean up streets and pick up rubbish, while others give speech to call on more people take action. But we can’t expect to save the earth only by one day’s work. Instead, we should make every day Earth Day. Only by taken good care of it every day can we make our planet a better world to live in.

Last month our class organized a hiking along the Chaobai River，which run through Hebei， Beijing and Tianjin． Much to my disappoint， I found the river was serious polluted． At that moment， I was determined to do what I could protect it． First， under my teacher's help， I used the equipments from the school lab to test the quality of the river water． But then，I used the data I had collected it to analyze the pollution of the water． Finally，I write a report on the pollution of the river to the local government． I also gave a presentation in class where I suggested that we must make small changes to protect our water resources．

Nowadays, the destruction of forests is one of most serious environment problems. From that I understand, people are destroying thousands of square kilometers of trees every day. This is killing hundreds of wild animals live in the forests. But something must be done. Unfortunately, we don’t do everything to protect the forests.
People who cut down trees should go to prison. That’s what happens in some country to people who sell plastic bags. That’s what should happened to people who destroy the forests. I can’t help but to think that we must protect wildlife for future generations. Hopeful, our children will be even much responsible that we are today.
