Urbanization commonly occurs in cities with low and middle income communities that have high population density and a lack of understanding of how climate change, which degrades their environment, is affecting their health. Within urban settings, multiple climate and non-climate hazards impact cities which magnify the damages done to human health.
Pathways through which specific global environmental changes affect urban systems (e.g., climate change impacts on urban areas; decline in ecosystem services on urban climate regulation). Urban responses to global environmental change (e.g., urban strategies for climate change mitigation and adaptation).
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.
Urbanization over the past 500 years [13] A global map illustrating the first onset and spread of urban centres around the world, based on. [14]From the development of the earliest cities in Indus valley civilization, Mesopotamia and Egypt until the 18th century, an equilibrium existed between the vast majority of the population who were engaged in subsistence agriculture in a rural context ...
New York City's Central Park represents an ecosystem fragment within a larger urban environment. Urban ecology is the scientific study of the relation of living organisms with each other and their surroundings in an urban environment. An urban environment refers to environments dominated by high-density residential and commercial buildings ...
Urbanization has large impacts on human and environmental health, and the study of urban ecosystems has led to proposals for sustainable urban designs and approaches to development of city fringe areas that can help reduce negative impact on surrounding environments and promote human well-being.

The built environment has a multitude of impacts on the planet, some of the most prominent effects are greenhouse gas emissions and Urban Heat Island Effect. [41] The built environment expands along with factors like population and consumption which directly impact the output of greenhouse gases.
Urbanization and environmental consequences has always moved hand in hand. Odum in 1989 has called cities as ‘parasites’ on natural and domesticated environment, since it makes no food, cleans no air and cleans only a little amount of water for reuse [6] and Mayur (1990) has argued that such disharmony may result in environmentally catastrophic events (cited in Leitmann, 1999).
