As more and more people own cars, more and more problem exist and cause, The popular problems we could see such as frequent accident increasing, highly emit emission, rush hour traffic jam, and so on. No doubtfully those greatly affect our normal environment and society.

 Among those problems we’re facing, I think the biggest one which influence people nowadays and even our future living is highly emit emission. Scientific prediction tells people the temperature in the future will be getting higher and higher as green house influence. The worse, people will suffer diversity and irregular weather which would occur to drought and flood. And the directly victims must be citizens and countries.

Even though there’re so many problems. Cars innovation is for convenient people to go around everywhere. However, if it convenient our moving but threat our life, we’d rather walk to go places we want. Yet we can’t live without cars, so we’d better to decline the effects as much as we can. I propose what if we could invent a car that one hand convenient people moving, but not threat our life. Not only individuals, but governments as well are considering this project. We’re sure we can conquer the problem one day and enjoy life that cars provide us.
