resource depletion
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 (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion.
Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels.〔(Depletion and Conservation of Natural Resources: The Economic Value of the World's Ecosystems — How Much is Nature Worth? The Role of Forests and Habitat )〕
== Causes ==
* Aquifer depletion
* Habitat degradation leads to the loss of biodiversity (i.e. species and ecosystems with its ecosystem services)
* Irrigation
* Mining for fossil fuels and minerals
* Overconsumption, excessive or unnecessary use of resources
* Overpopulation
* Pollution or contamination of resources
* Slash-and-burn agricultural practices, currently occurring in many developing countries
