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.

In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance. A decreasing CPUE indicates overexploitation, while an unchanging CPUE indicates sustainable harvesting. [1]
Harvesting at is also potentially unstable. A small decrease in the population can lead to a positive feedback loop and extinction if the harvesting regime is not reduced. Thus, some consider harvesting at MSY to be unsafe on ecological and economic grounds.
In a non-agricultural sense, the word "harvesting" is an economic principle which is known as an exit event or liquidity event. For example, if a person or business was to cash out of an ownership position in a company or eliminate their investment in a product, it is known as a harvest strategy.
A body farm is a research facility where decomposition of humans and animals can be studied in a variety of settings. The initial facility was conceived by anthropologist William M. Bass in 1981 at the University of Tennessee in Knoxville, Tennessee, where Bass was interested in studying the decomposition of a human corpse from the time of death to the time of decay.
The term food system describes the interconnected systems and processes that influence nutrition, food, health, community development, and agriculture.A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, distribution, and disposal of food and food-related items.
Sustainable yield is the amount of a resource that humans can harvest without over-harvesting or damaging a potentially renewable resource. [1]In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time. [2]
The depletion of resources has been an issue since the beginning of the 19th century amidst the First Industrial Revolution.The extraction of both renewable and non-renewable resources increased drastically, much further than thought possible pre-industrialization, due to the technological advancements and economic development that lead to an increased demand for natural resources.
