Large cities tend to attract people from different areas looking for life-changing opportunities, thus causing many inconveniences such as housing problems, traffic jam, and pollution. Motivating people to move to smaller cities or rural areas is a good solution.
A dense population brings about many issues. First of all, housing problems derive from informal settlements of the working class, which leads to the formation of slums like those in Mumbai, the insecurity of tenure and the lack of conventional basic amenities such as water and sanitation. Secondly, traffic can be a serious headache. Most people prefer privately owned vehicles because they are more comfortable, faster, and more flexible for doing multiple tasks on one trip than almost any form of public transit, which results in endless daily traffic jams like Los Angeles streets at 5PM. Together, the two aforementioned problems contribute to water and air pollutions due to raw and untreated waste disposal in slum areas and the significant emission of nitrogen oxide, carbon oxide, carbon dioxide etc. into the air. Look at Beijing, one of the most densely populated cities. Its citizens have been suffering from severe health problems due to acute air pollution.
Authorities, therefore, should encourage people areas of sparse population. Not only does this help reduce the problems in big cities, this also provides the citizens with the higher chance of employment. A small population decreases the intensity of competition between job seekers as there are fewer people applying for the same position. Australia used to succeed in implementing a decentralization program when Sydney encountered great traffic and pollution problems. The program gave companies incentives to set up in country towns and created many job opportunities for its citizens.
To sum up, an overly dense population in big cities undeniably causes a lot of issues: housing problems, congestion, pollution..., and governments should support the movement of people to smaller towns or rural areas.
