Urban greenery refers to the presence of plants, trees, and green spaces in cities. This includes parks, gardens, street trees, and green roofs. Urban greenery plays a vital role in improving air quality, reducing heat, and providing habitats for wildlife. It also enhances the aesthetic appeal of urban areas, making them more pleasant for residents and visitors. In addition to environmental benefits, urban greenery promotes physical and mental well-being. Access to green spaces encourages outdoor activities and social interactions. Cities with ample greenery, such as New York City with its Central Park, often report higher levels of community engagement and overall happiness among residents.
