The car-free movement is a movement to help reduce the number of cars on the roads. It encourages people to choose alternatives to driving, like bicycling, walking, taking the bus, carpooling, or using public transportation. The goal is to reduce air pollution, congestion, noise, and accidents, and also to get more people to enjoy exercising. It also helps to save energy, money, and time. It is important for people to think about the environment and their health when choosing how to get from point A to point B.
