The 21st century is by far the most productive era of all time. It is the age where man meets technology, where people change from using analog mechanical to digital computing. It is also the age where the industry had its revolution. This makes major countries and cities all over the world reach its peak. With the constant increasing number of human population and the never expanding land, the human population growth becomes higher and overpopulated.
If the increase of the human population goes on it could be a disaster. Given that Earth is in limited size, population growth will have to come to a close at some point. The only questions are when and how population growth will cease. Population growth is controlled at two points in the human life cycle. One is before birth, by artificial birth control and abortion. The other is after birth, by war, starvation, murder and other horrors beyond anyone’s imagination. And that what makes cities reasonably dangerous to live in.
The key issues which need to be considered to make cities better to live in for the future are mainly the uneven human population distribution and city planning. The three main factors that affect the scale of the human population distribution are the location of your home, workplace, and the transportation that connects both places. The urban planning of a certain city has a big impact on the distribution of human population. There are two examples of urban planning. First, in assumption the workplace takes place in the middle of the city and the citizens live surrounding the city by living in the suburbs. Second, citizens live and work in the city.
In best guess of the first example, suppose we have suburbs encircling the city. For example, we have Jabodetabek. It stands for Jakarta, the city and Bogor, Depok, Tangerang, and Bekasi is the outer edge. Citizens...
