VIII/ Read the passage below carefully, and then choose the best answer:
Conservation conflicts arise when natural-resource shortages develop in the face of steadily
increasing demands from a growing human population. Controversy frequently surrounds how a
resource should be used, or allocated, and for whom. For example, a river may supply water for
agricultural irrigation, habitat for fish, and water-generated electricity for a factory. Farmers, fishers, and
industry leaders vie for unrestricted access to this river, but such freedom could destroy the resource,
and conservation methods are necessary to protect the river for future use.
Conflicts worsen when a natural resource crosses political boundaries. For example, the
headwaters, or source, of a major river may be located in a different country than the country through
which the river flows. There is no guarantee that the river source will be protected to accommodate
resource needs downstream. In addition, the way in which one natural resource is managed has a direct
effect upon other natural resources. Cutting down a forest near a river, for instance, increases erosion,
the wearing away of topsoil, and can lead to flooding. Eroded soil and silt cloud the river and adversely
affect many organisms such as fish and important aquatic plants that require clean, clear freshwater for
survival.
