Cars and Pollution
China’s population of cars are increasing. This results in a very large amount of air pollution because huge amounts of waste gases are pumping into the atmosphere from millions of cars each day. These gases are very harmful, causing disease and even death. Besides, they can form heavy smog, making the sky gloomy for weeks and worsen the environment.
One possible solution is to design and develop clean fuels like natural gas which does not give off as much waster gas as the petrol. Another solution is to develop modern public transportation systems and restrict the number of private cars.
On the whole, the elimination of air pollution needs the co-efforts from the government and the public with the help of science and technology.
