Car and Air Pollution
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 poible solution is to design and develop clean cars and clean fuels.some of the public buses begin to run on 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 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 buy private cars.And the total number of cars in big cities will reduce greatly.
On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.汽车和空气污染
太多的车已经在我们的世界中创建很多严重的问题。除了交通挤塞、意外、快速油耗汽车负责在大城市的空气污染很大一部分。所有的时间，他们注入大量的废气进入大气。这些气体很大的损害，导致疾病、甚至死亡。
一个可能的解决方案是设计和开发清洁能源汽车和清洁燃料。在上海，一些公交车的开始天然气，并不给予出尽可能多的二氧化碳作为汽油上运行。但它可能需要几十年，为新的清洁能源汽车模型完全取代传统的。
另一个解决方案是发展现代公共交通系统和限制私家车使用。如果汽油价格不断上涨和公共车辆是高效、便捷没有足够的大多数人会购买私家车。与大城市的汽车总数将大大降低。
整体上，消除空气污染需要来自政府、公众和环保主义者的集体努力。
