The term "urban environment" refers to the physical surroundings and conditions in which people live, work or play within a city. This includes everything from buildings and infrastructure such as roads, bridges, and public transportation systems, to natural features like parks and green spaces, as well as social aspects such as demographics, culture, and economic activity. The urban environment encompasses the built and natural environments that make up a city or metropolitan area, and can have significant impacts on human health, quality of life, and sustainability.
