What is a potential consequence of unmanaged resource depletion?

The consequence of unmanaged resource depletion leading to scarcity of natural resources is a significant concern in geography and environmental science. When resources such as water, forests, minerals, and fossil fuels are extracted or consumed faster than they can be replenished, their availability diminishes. This can result in a situation where communities and economies face shortages, making it difficult to meet basic needs and sustain economic activities. The impact extends beyond just human use; it also affects ecosystems, which rely on these resources to function properly. Scarcity can lead to increased competition for remaining resources, potentially resulting in conflict and environmental degradation.

Contrasting options illustrate why scarcity is the primary concern. While technological advancements may improve efficiency in resource use, they do not directly counteract the effects of depletion if the resources themselves are being exhausted. Similarly, stable economic growth often depends on the sustainable management of resources; without them, growth can falter. Increased biodiversity typically stems from healthy ecosystems where natural resources are managed responsibly. When resources are depleted, biodiversity can decline, further exacerbating the issues associated with resource scarcity. Thus, unmanaged resource depletion directly results in scarcity, making it the most appropriate answer in the context of this question.
