text: When people drive cars they let out pollution into the air which harms the atmosphere. The advantages to this is that if people don't drive that much anymore the pollution can be stopped at a certain point and cause no harm anymore of course the air might still be polluted but with a less perentage. People would definitely use money on something else thtne to try and get the new car or just use it on gas. There are alternatives to limit the use of cars.
