Carbon Dioxide Emitted from Cars

Now days most of the cars all over the world works by three things gases, gasoline and diesel. When the three things start to burn that mean we affect the earth air and that cause Global Warming. People around the world used many cars some people have more than two cars for their family if each family have one big car it mean that will be less cars in the world so that mean we can reduce the carbon in the air. I think that cars manufactures should start to find or to do anther types of cars that my work by sunshine or electricity that me by helpful for us.
