A non-renewable resource (also known as a finite resource) is made up of deceased organic material. The organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Also considered non-renewable are resources that are consumed much faster than nature can create them. Fossil fuels (such as coal, petroleum, and natural gas), nuclear power (uranium) and certain aquifers are examples. Metal ores are prime examples of non-renewable resources. In contrast, resources such as timber (when harvested sustainably) and wind (used to power energy conversion systems) are considered renewable resources.
Famous quotes containing the word resources:
“Everywhere we are told that our human resources are all to be used, that our civilization itself means the uses of everything it hasthe inventions, the histories, every scrap of fact. But there is one kind of knowledgeinfinitely precious, time- resistant more than monuments, here to be passed between the generations in any way it may be: never to be used. And that is poetry.”
—Muriel Rukeyser (19131980)
