The Sustainable Grand Canyon Workshop
註釋The Grand Canyon was set aside in 1919 as "a public park for the benefit and enjoyment of the people." It spans 1.2 million acres and contains 5 of the 7 life zones, including 3 of the 4 desert habitats in N. Amer. The park is simultaneously a living science lab., an ecological refuge, the sacred ancestral homeland of native Americans, and a pilgrimage site for 5 mil. international and national visitors each year. This general mgmt. plan for the Park demonstrates sustainable development by preserving resources while simultaneously accommodating increasing visitation.
