Nowadays, commuting to workplace or to school takes people an increasing amount of time. There are numerous causes which lead to this unexpected change (noun), and I believe that it is a negative tendency. This situation is often caused by many factors. The first popular element is traffic congestion, especially in a rush-hour (không gạch giữa). This is generally because people tend to own at least one vehicle each person and have no interested in using public transportation, despite the increasing proportion of worldwide population. Therefore, traffic jams usually occur in the morning, when most people try to travel to their workplace or to school, as the enormous number of cars as well as motorcycles spill onto the streets. Furthermore, some people may attempt to lengthen the time that they use to get to work. This is because they use public transport regularly so that they do not have to drive by themselves, and thanks to that benefit, they could take those leisure time to have a quick nap or finish some tasks on the way to the working place. Spending a long time to go to work or to school brings about a negative influence on the society. The first impact is air pollution. Gas or carbon dioxide emissions, which come from many industrial factories or forest fires, are one of the most common pollutants that contribute to the contamination of the air (c nghĩ câu này ko cần thiết lắm vì ko nhắc tới vehicle mà nghĩa nó cũng giống giống câu sau). It is evident that excessive toxic fumes exhausted by vehicles pollute the air, and as long as these personal transportations are used, they will release a huge amount of toxic fumes into the environment. Those pollutants not only damage the ozone layers as well as contaminate the fresh atmosphere, but also do harm to people’s respiratory tract by some severe infections. Moreover, taking a long period of time just to get to work or to school might affect the schedule of that day. Spending more and more time commuting means that people have got less time for others activities, such as finishing tasks, enjoying themselves, hanging out with friends or beloved one, …. As the result, they will suffer from stress, or under some serious circumstances, they might get a mental health problem. In conclusion, the causes behind the phenomenon that people gradually spend more time commuting are traffic congestions and wanting to take advantages of the time when travelling. My firm conviction is that this trend is disadvantageous because of its consequences related to air pollution and the massive amount of work.
