text: As many people may already know, cars release greenhouse gasses that are harmful to our enviroment. As said in source 1, "Passenger cars are responsible for up to 12 percent of the greenhouse gas emissions into the enviroment." Parts of Germany are working to solve this issue by creating "car-free" communities. Some of these communities house up to 5500 residents. This change is getting a positive reaction, with more people moving into these commmunities than predicted. This is a movement called "smart planning" which is a trend that is growing and sreading into many parts of Europe, some parts of the United States and elsewhere.
