In most cities, or in many places in the United States, There are buses, subway systems, taxis, Lyfts/Ubers, and other forms of transportation services. You can also use your car, your bike, your skateboard, or walk.  But everytime you use a bus, car, or other form of motor-based transportation, you might be releasing harmful smog and gas pollution. In order to fix these harmful practices, there needs to be better options for transportation that help decrease this pollution. For example, the use of buses that use renewable energy. Using a rechargable battery for buses can decrease the amount of pollution caused by buses. In California, school buses that are electric are being implemented in some school districts. On a state or country level, there could be separate funding that supports or encourages the production of non-fuel based vehicles. On a personal level, you can opt for transportation that requires no type of gas or fuel. For example, using your bike or walking for going to close by places, is a small and simple way to decrease the amount of pollution your vehicle releases by relying on it less. If you are going long distance, you can opt for buses that use eco-fuel or are electric, also decreasing the amount of pollution your vehicle releases.
