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.

Some cities are often believed to face a looming crisis concerning their overcrowding, which is the root of various problems. There is widespread concern about
one
of the main issues related to the degradation of the environment, which is probably could be resolved by certain measures
such
as implementing green infrastructure in cities by local authorities along with environmental-friendly behaviour from city dwellers. The most principal challenge for overpopulated cities is
air
pollution and soil contamination. Rarely do people realize the impact of numerous amount of private motor vehicles participating in traffic. which are in turn causing an intense emission of exhaust gases.
As a result
, these toxic and harmful health substances promote smog in the
air
as well as acid precipitation which
then
pollutes the groundwater. To illustrate, in 2017, the United States transportation system contributed more than half of the carbon monoxide and nitrogen oxides emitted into the
air
, which has caused an increase by
one
-
third
respiratory ailments like asthma and bronchitis. On the
one
hand, it is quite evident that
one
of the possible measures to be introduced by the government for solving
this
problem is providing a green ecosystem in and around the urban areas promoting by the government. On no account should the impact of trees producing oxygen and cleaning the
air
by acting as giant filters, removing harmful particles and pollutants be ignored.
On the other hand
, not only should the local authorities being involved in reducing environmental impact, but
also
urban residents play a significant role in
this
approach by moving to fuel-efficient vehicles that use less oil, or produce fewer emissions, and electric cars, that can entirely remove tailpipe emissions. On
this
occasion, strong state policies about requirements of car use are certain to be as additional maintenance. In conclusion,
one
of the main problems caused by high-density populating cities is environmental impairment,
such
as
air
pollution and soil contamination.
One
of the devised ways to solve
this
problem is concerning greening the environment in urban areas together with encouraging local citizens to switch to a more eco-friendly approach to using passenger vehicles, thereby reducing the influence on the environment
