Scarcity, in the area of social psychology, works much like scarcity in the area of economics. Scarcity is basically how people handle satisfying themselves regarding unlimited wants and needs with resources that are limited. [1] Humans place a higher value on an object that is scarce, and a lower value on those that are in abundance.
Environmental science studies to what extent human populations through their resource consumption have risen above the sustainable use of resources. For people, "overshoot" is that portion of their demand or ecological footprint which must be eliminated to be sustainable, or the delta between a sustainable population and what we currently have.
Scarcity affects the functioning of the brain at both a conscious and subconscious level, and has a large impact on the way one behaves. The authors suggest that scarcity has a tendency to push us into a state of tunneling: a focus primarily on the scarcity of a resource, and a resulting neglect of everything else “outside” the tunnel. When ...

[2] The opposite of scarcity is abundance. Scarcity plays a key role in economic theory, and it is essential for a "proper definition of economics itself". [3]
Water resources, such as lakes and aquifers, are usually renewable resources which naturally recharge (the term fossil water is sometimes used to describe aquifers which do not recharge). Overexploitation occurs if a water resource, such as the Ogallala Aquifer , is mined or extracted at a rate that exceeds the recharge rate, that is, at a rate ...
In 1974, Hardin published two articles describing his view of "lifeboat ethics" in Psychology Today [2] and BioScience. [3] At the time, based on per-capita gross national product, Hardin asserted that approximately two-thirds of the world's population was "desperately poor" and the remaining one-third was "comparatively rich" before launching his metaphor of each rich country being in a full ...
Thomas Robert Malthus, after whom Malthusianism is named. Malthusianism is a theory that population growth is potentially exponential, according to the Malthusian growth model, while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population decline.
