Overexploitation

Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Sustained overexploitation can lead to the destruction of the resource. The term applies to natural resources such as: wild medicinal plantsgrazing pasturesgame animalsfish stocksforests, and water aquifers.

In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at a rate that is unsustainable, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. 

 Overexploitation can lead to resource destruction, including extinctions. Overexploitation is not an activity limited to humans. Introduced predators and herbivores, for example, can overexploit native flora and faunahttp://en.wikipedia.org/wiki/Overexploitation
