The purpose of this legislation, known as the "Activating National Parks in Cities Act," is to broaden the role of the National Park Service. Specifically, it aims to encourage the active use of national parks and similar areas located in urban settings. The goal is to enhance the enjoyment of these spaces for people living in cities and improve their overall quality of life. Key provisions of the legislation include a change to the National Park Service's mission, which will now explicitly include promoting active use of urban park units.
