Seoul, the Biggest City in the World

Seoul, the heart of Korea, has 10,356,000 of population. Compared to all of South Korea's population, it is about one fourth. Due to the population of the city, Seoul has numerous problems. The air is stuffy almost every day, there are too many cars on the road, and the streets are full of trash. Lately the government of Seoul is trying to make it better; they have worked out the restorations of Chunggye Creek and Seoul Forest. Seoul accomplished two successful jobs, but still it needs a lot of work. Too many people in limited space caused increase of living cost, and it caused pollution of the city too. Too many cars and factories generate chemical gases, and the gases are all around people. The air pollution can cause some diseases such as asthma and allergies. We should make Seoul clean, and it needs the voluntary help of the citizens.
