Overpopulation of urban areas - problems and solutions

Hi, would anyone help me to tune my essay writing,

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.

Introduction
Over the decades, there has been significant increase in the population of cities. Some analysts believe that, governments should take notice and handle the situation; while on the other hand some believe that individuals and governments need to tackle overpopulation problems. In this essay, I would assert on problems and solutions of urban areas due to overcrowding before delivering an appropriate conclusion.
