Yesterday, our school made a survey about private cars. Some students think it’s easy for people to go by car. But most students don’t agree. Neither do I. Cars can cause more serious pollution. The more people travel by cars ,the worse our world will be. What’s more, the traffic will be heavier. As a result, there will be more traffic accidents.
In my view, we should walk or go by bike instead of by car. We can also take a bus when we travel for a short distance. We should do what we can to protect our environment. Let’s begin now.
