This growth was caused by a number of factors and resulted in both positive and negative consequences. Such factors included, industrialization, technological advances, migration and immigration. Although American cities greatly improved by the expeditious urbanization, these factors also developed numerous challenges including pollution, sanitation problems, a need for environmental reform, political corruption, overcrowding, high crime rates and segregation.

Sustainable cities are an ecosystem with not many environmental issues. Some of the issues that are not present within a sustainable city are air pollution, mass population and excessive water and energy usage. A sustainable city does not have a negative impact on the environment. It has a small ecological footprint, which is the impact of a person or community on the environment.

Planning and management needs to happen in all countries over the world because no matter how different the level of development between countries the problems will be same in urban areas.

As more people migrate to urban areas in search of better work opportunities, the cities here are growing in size and number (Ferguson & Navarrete, 2003). This problem is native to not just Latin American countries but is a major concern for most of the developing world. As estimated by the UN (United Nations, 2016), 3 billion people or about 40% of the world population would be living in substandard housing as a result of urban expansions and population growth. This is perceived to be a direct impact of rapid urbanization and excessive strain on

According to Britannica, Urban Sprawl is defined as “the rapid expansion of the geographic extent of cities and towns, often characterized by low-density residential housing, single-use zoning, and increased reliance on the private automobile for transportation” (“Urban Sprawl”). There are many effects of urban sprawl, both positive and negative; though the negative outweigh the positive in quantity, but not necessarily in importance. Whether or not urban sprawl is a good

Urbanization is likely to be one of the defining phenomena of the 21st Century for Latin America as well as the rest of the developing world.
