What is megacity?
The last century clearly showed us that migration to cities is the trend of the present and the future. In 1800 it is estimated that less than 3% of the world's population called cities their home. At the turn of the 21st century, this issue exploded and some experts estimate that almost half of all people lived in cities. This massive migration from the country and to the city led to the rise of megacity , a term that is usually used to describe the city with a population of more than 10,000,000 inhabitants.
Cities have been part of human civilization for thousands of years, they have been rising from early tribes as symbols of power, trade and gathering places for cultural and religious events. Since society has moved away from agricultural persecution, which requires a large amount of land, development and growth of cities naturally increased dramatically. Although there are many factors that have led to the development of megacit, dependence concerning technology, population growth and economic development of poor nations are often referred to as headcontributors to their rise.
It is somewhat difficult to obtain the exact population of the city, because the population census is somewhat inaccurate in its estimate. In addition, there are some disputes over the experts about what secluded urban areas, such as suburbs, are to be included in the population. Regardless of these difficulties, it is generally believed that at least 26 cities meet the criteria of 10 million inhabitants, with many other cities at the top of the connection. Tokyo with more than 35 million inhabitants is currently the largest megacity.
Megacity allows comfort and good opportunities to find work, but are full of complicated problems. Many traditional cities, such as New York City and Los Angeles, have not been built so that they hold NY and face countless questions, how and where to spread to meet their growing populations. Sanitation, crime and poverty are strict problems to face megacity and fewWho has found sufficient ways to deal with these problems. But perhaps the biggest challenge that will face megacity is the development of slums or cities chatting along the boundary of the developed city.
Modern megacity is barely limited to rich countries such as the United States; In fact, they are more common in countries where there is a huge economic division between rich and poor. As a result, people who desperately need work available only in the city cannot afford to live there and are forced to live in dangerous, cheap slums. Slum areas are usually outbreaks of crime and serious hygiene problems, leading to extremely high mortality and risk of rapidly spreading diseases. Because many slums are also illegally built, they leave the inhabitants in a security as a result of natural disasters such as earthquakes or floods.
According to most population experts, it is here to stay despite its problems. Optimists hope that the development of a global community will help disperseSome problems associated with megacita support the economy of developing nations. However, Megacita has long been a popular environment of fascinating fiction works that depict a fixed, ecologically destructive future for city residents. In the mid -21st century, it is believed that three out of five people will live in cities; Obviously, the time to find megacity problems is now.
