Cars and Pollution In nowadays,as the increasing of people’s living level,more and more families buy cars for the convenience of living necessary. However, Too many cars have created a lot of
serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death. One possible solution is to invent and develop clean cars and clean fuels. In the world, buses in some cities are driven by electricity, while others begin to use natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not private cars. And the total number of cars in big cities will reduce greatly.
