tokens: Government should regard investing in building roads as the most important The population explosion results in the high demands of transportation . Many countries have suffered from pollution, noisy and casualty for a long time . From my perspective, the most possible solution to these problems is improving roads and highways because of three crucial reasons . First and foremost, we all know that upgrading public transportation will surely aggravate the pollution and accidents . The buses, cars and trains regularly emit a noxious gas which causes lots of fatal diseases such as lung cancer and pneumonia . Moreover, the sound emanates from the engines can worsen our hearing . Most importantly, there are many accidents happening on the roads . For example, in my country, buses are attributed to the cause of skyrocketing of accidents . Each year, Vietnam has approximately twelve thousand people die of accidents which is equivalent to the death toll of the tsunami in Japan . Secondly, investing in roads and highways can broaden the area and allow more public transportation to work . Not only buses but also other personal vehicles can move easily on the roads . For instance, I always leave school at the time that everybody rushes into the roads and hastily goes home . It is extremely troublesome for me to escape from the crowd on the roads in only one hour . In contrast, if the roads are enlarged, everyone can go home in short time and there are hardly any collisions . Last but not least, spending on renovating the highways and roads can improve the quality . All of us are afraid of moving on the rough roads with lots of portholes . Those bad conditions result in many terrible accidents and make several people feel worried . We should not accuse the drivers of causing accidents because a part of the responsibility belongs to the authorities . What's more, a smooth surface makes the transportation and movement become safer and easier . In a nutshell, the advantages of upgrading the roads which I mentioned above are totally convincing and indispensable . I am usually inclined to this idea and I hope that the government will regard the investment in building roads as the most important thing .
