Overpopulation of urban areas has led to numerous problems. Identify one or two serious ones and suggest ways that governments and individuals can tackle these problems.

All over the world, cities are choked by the numbers of people that they attract. The industrialization of agriculture has led to more and more people fleeing the countryside and looking for work

sites

.

As a result

, the population of urban areas is

growing but

growing, but

the respective infrastructure is not always up to the challenge. One of the main problems arising from

this

trend, in my opinion, is the level of

pollution

, especially

air

pollution

from motorized traffic.

Smog

has become a ubiquitous problem in cities. Cars, lorries,

vespas

- they all spew pollutants into the

air

that are not easily contained or cleaned up. The more people arrive in an urban area, the more there is a need for

transport

, both of goods and of people. While

smog

in itself is unpleasant, there is a flow-on effect

can cause serious respiratory illness and even death.

This

means that urban

air

pollution

is not simply an aesthetic issue, but is indeed a severe

health

problem that drains public

health

systems. It is

thus

in the best interest of governments to tackle

this

issue. One obvious solution to the problem is an investment in rail-based infrastructure, which provides a means of

transport

that doesn't produce

smog

.

Such

an investment should include both public

transport

transport

of goods.

Furthermore

, governments could initiate public

health

campaigns, including advertising, to better educate the public about the risks of

smog

. Individuals,

have a role to play. They can make an effort to

In addition

, a lot of traffic can be avoided if one simply chooses to live near the workplace. In conclusion, it is unlikely that the influx of people into urban centres is coming to a halt anytime soon. Among the many problems
