Overpopulation of many urban centres around the world is a major problem. What are the causes of this and how can this problem be solved?

With world population reaching 7 billion of people, most of them live in urban centres. In fact, among the

last

few centuries, mankind has left the countryside in order to find employment and a better life in industrial areas, yet causing a problem of cities overpopulation. In my opinion, though, there are a number of possible solutions that have to be taken into account. A few reasons have led to

this

issue: one of those can be found quite back in time. As a matter of fact, it was during the industrial revolution that people started migrating front the countryside to the cities, in order to find a job in factories. With the consequence that

this

phenomenon has pushed industrial areas into degradation and poverty.

However

, there is another yet opposite reason: today

third

-world cities population is exponentially growing because of widespread unemployment and poverty, along with a total absence of birth control and social prevention. Solutions can be suggested to face

this

world-spread problem. On one hand, birth control policies should be considered as a start, especially in countries like China, India and Brazil,

were

In or at or to what place

where

the most of the so called megalopolis find place.

On the other hand

, the governments of those countries that are most affected by the issue, should offer a better social assistance,

also

trying to provide new job positions outside the cities, pushing for a

requalification

of the countryside, in order to spread urban population. In conclusion, urban overpopulation is a world-spread issue, which impact is exponentially growing. In my opinion, only the activism of policy makers would help changing the situation, with social

sensibilisation

as well as with providing a wide number of new occupations outside the city environment.
