In Arkansas, the renewable natural resource that could actually run out if sustainability practices are not kept in place is timber. While timber can regenerate, unsustainable logging practices can lead to deforestation and depletion of forest resources. If forests are not managed properly, they could become degraded, leading to a reduction in timber availability and loss of biodiversity.
Natural gas and bromine, on the other hand, are not considered renewable resources and can be depleted regardless of sustainability practices. Solar power is considered a renewable energy source with virtually limitless potential, as it relies on sunlight. However, the infrastructure and resources required to harness solar energy can still pose sustainability challenges, but the resource itself (sunlight) will not "run out."
