How does driving gas cars impact global warming?

First, the more cars there are means more roads. This means less land and cutting down trees to make room for roads. The roads take time to put down but it can ruin some animal hibitats. Cars come in many different sizes. These can be really big or even really small. This really does make a difference on how much gas the car uses, the more gas used the more polution produced by the car. Cars produce gases that are NOT good for the earth and doesn't help global warming at all. If you want to make a difference then car pool. Ride your bike to the next block because this saves money and the planet all at the same time. This is gives you benifits also. So help save the planet, help defeat global warming.
