text: While saving money on gas, you would save the enviornment from the gas. Vehicles cause a lot of pollution and can even build a layer of smog over cities. These layers of smog get stuck in the air, making the area it's around warmer. The amount of pollution within the world is absurd, and if everyone were to stop using vehicles that would cut down the total pollution by a large portion. Lower air pollution is also shown to take away stress, and lowering the use of your vehicle would also get rid of the stress of other drivers.
