A sustainable city is designed to minimize its environmental impact while promoting the well-being of its residents. It focuses on efficient use of resources, such as energy and water, and incorporates green spaces, public transportation, and renewable energy sources. This approach helps reduce pollution and enhances the quality of life for its inhabitants. In a sustainable city, urban planning prioritizes walkability and accessibility, encouraging people to use bicycles or public transit instead of cars. Additionally, buildings are often constructed with eco-friendly materials and designed to be energy-efficient. Overall, sustainable cities aim to create a harmonious balance between urban development and nature.
