Urban problems

Crime rate
The bigger and the richer the city is, the higher the crime rate is - more thefts and robberies. Because the city is urbanized, the police have issues with finding the criminals.
Housing
There is a housing shortage in urban areas - the migration of people to the urbanized areas causes high population density and the people have to move to the suburbs. The constant migration from rural to urban places causes lack of housing and basic services.
Pollution
Antropogenic sources such as factories, industries, transportation etc. create pollution in urban areas. Richer cities produce better quality energy, use eco-friendly resources.
Traffic
When the population of the city increases, people in the urban area buy more cars. Then they drive their cars to work and suddenly there is too many cars in the center of the city. Traffics can last for many hours, sometimes even days. It also badly affects the air in the city, creating air pollution.
Inequalities
There are many inequalities in the urban areas - poor and rich people live near each other. Even though they share the same land, they have a different access to food, education, housing etc.
Land use
When more and more people want to get a job in the urban area, they need more housing, which is lately becoming a big problem, because the number of places to build new houses decreases.
Urban problems of Seoul
Seoul is a megalopolis and the capital of South Korea. It is a place to live for 20 million people. One of the problems of Seoul is the housing shortage. Many multi-storey buildings are constructed to provide shelter for people, however, only 45% around the city can be urbanized. Many tall buildings next to each other can increase the population density. The high population density can also lead to huge traffic - by 1994 there were already 2 million cars in Seoul.
Urban problems of Seoul - part 2
Seoul is also a very polluted city, which is because of cars and factories, but also due to the Cheong Gye Cheon River, which has been polluted with many harmful elements, such as lead or chromium. The government works on the restoration of the river, but it will take years to take all of health risk away from it.
Urban problems of Mexico City
Mexico City is the capital of Mexico - a country in the North America. The city is a megalopolis, which is inhabited by 20 million people, same as Seoul. It is an example of an urban sprawl. The main problem of this city is that its poorer regions rarely have an access to public transportation. They also have a water shortage, as the water arrives in trucks.
Urban problems of Mexico City - part 2
There is also a lot of waste generated in the Mexico City - 4 million cars in one city,and the factories create huge amounts of pollution. Building multi-storey buildings might seem to help fight with the problems, but that also creates other issues, like traffic and the increase in population density.
