Answer:
Chinese cities were not originally built with the idea of high infrastructure that modern living requires. The roads are too narrow and not convenient for travel, and the traffic jams are a regular problem in the country. The number of drivers is increasing every day, as economic grown has made owning the car rather popular. The pollution from car emissions is one of the major environmental hazards that threaten nature and public health. Therefore, China is working hard on developing an intelligent public transportation system and cars that don’t harm the environment.
Explanation:
China is a country with a long history, and many of the cities have existed for a long time. <u>At the time of their development, there were no cars, and there was no need for the developed infrastructure that modern life requires.</u> With the development of the country and overpopulation, the majority of people started using the car and the traffic became oversaturated. There are now more cars than the roads and cities can handle. <u>The roads are not wide enough or placed conveniently for people to reach the destination fast and easy.</u> In 2010. massive traffic jam on National Highway in China went into history – the line of cars went for over 100 kilometers and lasted for 5 days, and many people reported being stuck their cars for the whole time.
Even though China has developed public transport system, many people use cars. <u>With the Chinese economic rise, people would buy cars, sometimes even just to show off wealth. There are almost 1200 new cars every day.</u>
<u>Additionally, this affects the environment. China is notorious for bad air pollution, and it is estimated that 55% to 70% of pollution comes from exhaust gases that come from cars. While new cars usually have lower emissions, overpopulation and too many cars still affect the environment.</u>
Thankfully, the government has started working on the problem, regulating traffic, and creating an even better public transport system. China’s citizens are regularly encouraged to use public transport and avoid using cars. On top of that, they are developing more environmentally friendly cars and other means of traffic on the regular basis. <u>There are notable improvements in the “Green travel” industry that increases usage of metro internet programs that help people plan their journey, staying on the road as little as possible.</u>
