The earth is our common home. But it is facing serious environmental problems now.

The earth is becoming warmer and warmer. Many rivers are badly polluted, and many forests are getting smaller. The main reasons are that people drive too many cars, cut down plenty of trees, and produce too much waste.
As students, we should take action to protect the earth. We can save water and electricity in our daily lives, and we can walk or ride bikes to school. Besides, we should stop using plastic bags and plant more trees. It's also helpful to throw rubbish into bins and advise others to live a green life.
Let's work together to make the earth cleaner and more beautiful.
