Only when we realize the importance of protecting the environment are we willing to do something for it. Have a try to change our way of life to reduce the pressure we put on the environment. Instead of driving a car, take a bus or cycle to work if possible. At home, we should use products which are

more energy-saving. Turn off the lights and anything else when we are to leave. Recycle those things that are not in use as much as possible. Don’t throw them away. Last but not least, we can do our parts to protect the environment and we need to take action immediately.
