I think this wise to go to school on foot. First of all, walking to school is wonderful way to exercise and it’s good for health. Next, it’s fun to walk together and friends every day. We can talk about interested things and knowing each other better. What’s worse, if we walk, our parents won’t have to drive you to school. There will have fewer cars in the city. More walking and less driving help to make our city the cleaner. The streets won’t be as crowd as they are now. I hope more and more students will go to school on foot.

People use them when enjoy a cold drink, but according to an app where maps trash, plastic straws are the six most common form of litter in the world. Plastic straws can't be recycled.

Recently I took a part in a geography research activity, whose theme was environmental pollution and protection. We took variety pictures showing the present pollution conditions of our city. To our surprise, there are still a great number people doing silly things to our surrounding. Some people often throw rubbish whichever they like. Some cars gave off harmful gases and waste water is pouring into rivers by some factories. Worse still, people sometimes have to make his way through dusty winds as a result of the pollution. Through our research, we have come to realize what everybody must pay more attention to protect our environment and that some measures should be taken to protect it.
