Why do we need stretches of uninhabited and undeveloped land?
What will be an ideal response?
Large stretches of undeveloped land provide natural resources such as timber and food. Areas of natural land provide ecosystem services, including purification of water and air, nutrient cycling, waste treatment, and escape from the stresses of urban life. They provide open space, greenery, scenic beauty, and places for recreation. They also provide habitat for wildlife, which satisfies our natural affinity for contact with other organisms. In addition to the utilitarian reasons cited above, many people feel an ethical obligation to preserve wild landscapes and biodiversity for the sake of nonhuman organisms and/or the integrity of ecological systems.
