If governments give incentives to drivers of electric cars, it can make a real impact in the pollution problem. A lot of electric cars are more expensive than their conventional counterparts, so the price deters some people from purchasing them. The government should defray part of the cost in order to protect the environment.
People don't like change. Sometimes they need some motivation to help push them in the right direction. I think this woul be a wise investment for the government to make, becaue it would help to make the environment cleaner and preserve our way of life for many of our future generations.
