t is important not to use your car or any other vehicle that spreads CO2 which is bad for the environment. The gas CO2 destroys the Ozone layer. My dad, in theory, drives a vehicle to work every day; even though he still minimizes the CO2 discharge when he uses the public transportation from time to time. The public transportation is a good thing for the globe, because many people use one bus and then there are fewer cars on the road.
