A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1]
From the human perspective, resources are non-renewable when their rate of consumption exceeds the rate of replenishment/recovery; a good example of this is fossil fuels, which are in this category because their rate of formation is extremely slow (potentially millions of years), meaning they are considered non-renewable. Some resources ...
Natural resources are resources that exist without actions of humankind; this includes characteristics such as magnetic, gravitational, and electrical properties and forces. Resources may be classified as renewable or nonrenewable .
Another non-renewable resource humans exploit is subsoil minerals, such as precious metals, mainly used to produce industrial commodities. Intensive agriculture is an example of a mode of production that hinders many aspects of the natural environment , for example the degradation of forests in a terrestrial ecosystem and water pollution in an ...
As some of those aquifers formed hundreds of thousands or even millions of years ago when local climates were wetter (e.g. from one of the Green Sahara periods) and are not appreciably replenished under current climatic conditions - at least compared to drawdown, these aquifers form essentially non-renewable resources comparable to peat or ...
Norge Mining said up to 70 billion tonnes of the non-renewable resource may have been uncovered in south-western Norway, alongside deposits of other strategic minerals like titanium and vanadium.
Such conditionally renewable resources are sometimes classified as a third kind of resource or as a subtype of renewable resources. Conditionally renewable resources are presently subject to excess human consumption and the only sustainable long-term use of such resources is within the so-called zero ecological footprint, where humans use less ...
A good example where recycling makes a big difference is the resource availability situation for graphite, where flake graphite can be recovered from a renewable resource called kish, a steelmaking waste created when carbon separates out as graphite within the kish from the molten metal along with slag. After it is cold, the kish can be processed.
