City Green Zones are designated areas within urban environments that prioritize green spaces, such as parks, gardens, green roofs, and tree-lined streets. These zones play a crucial role in enhancing the quality of life for city dwellers by providing much-needed natural areas for recreation, relaxation, and environmental benefits. They help reduce the urban heat island effect by lowering temperatures in densely built environments and improving air quality by filtering pollutants and increasing oxygen levels. 

In addition to their environmental benefits, city green zones foster social interaction and community well-being. They provide spaces for outdoor activities like walking, jogging, picnicking, or sports, helping to promote healthier lifestyles.
