Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources. The use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. [1]
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
The exploitation of natural resources describes using natural resources, often non-renewable or limited, for economic growth [1] or development. [2] Environmental degradation , human insecurity, and social conflict frequently accompany natural resource exploitation.

Depletion of natural resources is associated with social inequity. Considering most biodiversity are located in developing countries, [16] depletion of this resource could result in losses of ecosystem services for these countries. [17] Some view this depletion as a major source of social unrest and conflicts in developing nations. [18]
The first model is defined by Hotelling's rule, which is a 1931 economic model of non-renewable resource management by Harold Hotelling. It shows that efficient exploitation of a nonrenewable and nonaugmentable resource would, under otherwise stable conditions, lead to a depletion of the resource.
According to their accounts, humanity's demand for resources is now equivalent to that of more than 1.7 Earths. [5] The data shows us on track to require the resources of two planets well before mid-21st century. They state that the costs of resource depletion are becoming more evident.
A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery. The diagram is used to estimate the uncertainty and risk associated with availability of a natural resource.
