由于大量森林砍伐和其他土壤退化活动，城市化导致生态系统退化。地球景观因城市发展和其他人类活动而改变，这些活动可能会带来广泛和长期的负面影响。较早前，野生动植物将农业用地指定为森林形式的栖息地，由于城市化和森林砍伐，如今已不复存在，导致土壤侵蚀，并且还受到政府政策的影响。内陆和沿海水体受到农业用地径流的影响。城市发展对全世界的人类健康，耕地生产力和海洋生物多样性造成威胁。当森林用于城市化时，会增加土壤侵蚀，大气中二氧化碳和洪水的机会。它改变甚至消除了地球上的植物覆盖层，并导致大气中二氧化碳的浓度增加，集热气体的变化，甚至随着能量平衡的变化而导致局部，全球和区域气候变化。在地球表面。城市发展的剩余物富含沉积物和有毒污染物，这些物质会耗尽土壤表层，使其不适合农业用途。

Urbanization leads to the degradation of ecosystems because of immense deforestation and other soil degradation activities. The landscape of earth is altered because of urban development and other human activities which can have wide and long term negative consequences. Earlier the agricultural land was shared by wildlife specifies  as their habitat in the form of forests which now no longer exists due to urbanization and deforestation and resulted in soil erosion and is also influenced by governmental policies. The inland and costal water bodies are affected by the runoffs from agricultural lands. Urban development leads to threats to human health, productivity of agricultural lands and biodiversity of marine life all over the world. When forests are used for urbanization, it increases chances of soil erosion, carbon –dioxide in the atmosphere and chances of floods. It alters and even removes the earth’s vegetative cover and results in increasing the degree of concentration of carbon dioxide in the atmosphere, changes in the heat trapping gases and even leads to changes in the local, global and regional climatic changes with changes in the energy balance on the surface of the earth. The leftovers of urban development are rich in sediments and toxic contaminants which can deplete the top layer of the soil and make it unsuitable for agricultural purposes.
