Nonrenewable resource

From Free net encyclopedia

Template:Mergeto

A nonrenewable resource is a natural resource (such as a mineral, plant, etc,) that is used too quickly by something to be replenished, or that cannot be replenished at all. Examples are rain forests, fossil fuels, such as oil, natural gas, etc.

Nonrenewable resources cannot be renewed because the earth's processes by which they are formed either take too long to create the new material, are very complicated and require intense earth processes (heat, pressure), or it is impossible to regenerate what has been lost or used (as in the case of an extinct animal species).
