Bicycle English composition

Bicycle is a popular means of transportation. It is an environmentally friendly means of transportation. When I go traveling or shopping, I like riding a bike. Cars are becoming more and more popular now, but I think it will bring us a lot of damage. First of all, it will release a lot of waste gas, which will lead to global warming. Second, the number of cars is increasing, and crowded traffic will definitely bring security risks. So I think cycling is a better choice if we consider the environment.
