Green spaces are areas covered with vegetation, such as parks, gardens, and forests, that provide a natural environment in urban settings. They play a crucial role in enhancing the quality of life by offering recreational opportunities, promoting physical activity, and improving mental well-being. These spaces also contribute to environmental health by improving air quality, supporting biodiversity, and helping to regulate temperatures in cities. Examples of green spaces include Central Park in New York City and Hyde Park in London, which serve as vital lungs for their respective urban areas.
