text: In addition to lowering emissions, another advantage of limiting car usage is it would conserve resources. Think about how many cars are in the world. THERE ARE ALOT! So every car in the world uses resources to keep it running, even electric and hybrid cars eventhough they are a great alternative. But most use fossil fuels. The world doesnt have a unlimited supply of fossil fuels. It took millions of years t make the gas we put in our cars. So eventually we will run out and when we do it will take a very long time to get it back. Also think about the generation of people after us. What will we leave behind for them?
