Urbanization has many environmental consequences. In all urban areas there are numerous impacts on the environment such as air pollution, water pollution, etc. Excessive urbanization creates risks (fragilization of soils, pollution, plundering of natural resources) [6] Urbanization is one of the causes of the erosion of biodiversity.
The Urbanization and Global Environmental Change Project (UGEC) is one of the core research projects of the International Human Dimensions Programme on Global Environmental Change (IHDP). UGEC aims to understand the bi-directional interactions between urbanization and global environmental change .
Urban runoff contributes to water quality problems. In 2009 the US National Research Council published a comprehensive report on the effects of urban stormwater and stated that it continues to be a major contamination source in many watersheds throughout the United States.
Urbanization over the past 500 years [13] A global map illustrating the first onset and spread of urban centres around the world, based on.

Environmental issues in New York City are affected by the city's size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River. New York's population density has environmental pros and cons. It facilitates the highest mass transit use in the United States, but also concentrates pollution.
Documented problems associated with noise in urban environments go back as far as ancient Rome. [4] Research suggests that noise pollution in the United States is the highest in low-income and racial minority neighborhoods, [ 5 ] and noise pollution associated with household electricity generators is an emerging environmental degradation in ...
