On September 3, 2015, Beijing had a huge parade. There were 12,000 troops▼, hundreds of fighter jets, and dozens of military formations▼. Millions came out to check it out. Before the parade, Beijing didn't allow half of the cars to be on the roads for two weeks. During that time, the skies that were usually full of smog▼ became deep blue. After the parade, the cars were let back on the roads, and the smog returned.
This is just a small example of what removing cars can do. World Car Free Day is on September 22. On this day, people are encouraged to travel by bicycle, use mass transportation▼, or walk to any place they need to go to. Once they do this for one day, they realize that it’s not so bad. Then, maybe some people will make every day a car-free day. Once more people do it, pollution will go down, and the world will be better.
In Taiwan, public transportation systems are some of the safest, fastest, and best in the world. The more people use them, the more they will help the environment and everyone.
