For example, lots of rubbish is produced and it is harmful to the environment. As teenagers, we should take action to protect the environment. First, we’d better walk or ride a bike to school. Second, turn off the lights and taps when we don’t need them. It saves money and causes less pollution. Finally, divide our rubbish into plastic, glass, paper and rubber so that we can recycle it easily. We can’t hope for a rapid change, but if everyone starts to pay attention, the environment will be better and better. We should remember that it’s everyone’s duty to protect the environment. 优秀范文2 How to be a green teenager These days, the environment is facing more and more serious problems. For example, plastic bags and bottles are often thrown everywhere, which not only pollute the land but also harm wild animals. As middle school students, we have a responsibility to make a difference. First, we’d better choose to walk or ride bikes to school every day, as this can cut down on air pollution. Second, we need to develop the habit of turning off lights and taps immediately after use to save energy and water. Finally, we should learn to divide our daily rubbish into recyclable and non-recyclable groups, so that useful materials can be reused. We can’t expect the environment to get better overnight, but if each of us starts to pay attention to small actions in daily life, our earth will become better and better. After all, protecting the environment is everyone’s duty.
