The promise of jobs and prosperity, among other factors, pulls people to cities. Half of the global population already lives in cities, and by 2050 two-thirds of the world's people are expected to live in urban areas. But in cities, two of the most pressing problems facing the world today also come together: poverty and environmental degradation.

Following are the major impact of urban overpopulation:

  • Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people.

  • Concentrated energy use leads to greater air pollution with a significant impact on human health.

  • Automobile exhaust produces elevated lead levels in urban air.

overpopulation problems

  • Large volumes of uncollected waste create multiple health hazards.

  • Urban development can magnify the risk of environmental hazards such as flash flooding.

  • Pollution and physical barriers to root growth promote loss of urban tree cover.

  • Animal populations are inhibited by toxic substances, vehicles, and the loss of habitat and food sources.

These are the major impacts of urbanization. Poor air and water quality, insufficient water availability, waste-disposal problems, and high energy consumption are exacerbated by the increasing population density and demands of urban environments. Strong city planning will be essential in managing these and other difficulties as the world's urban areas swell..
