Philadelphia has been acclaimed for its vast network of parks and open space, which provides citizens with access not only to green space and playgrounds, but to a variety of programs, such as farmers' markets, that enhance the quality of life for city residents. Enhancing and expanding the parks are components of the goals for Greenworks Philadelphia, the city's plan for becoming the most sustainable city in the country.
