Recursos

Renewable resources are those that regenerate rather quickly: timber, fish, etc.., (As long as the techniques are appropriate capture or cut).
Within the renewable natural resources we can includeall those which, although used by humans for a period later reappear on Earth.
They are renewable natural resources, such as plants that man takes to feed. Even if the man uses the wheat to makebread, the next year grows wheat in the fields if they have been grown
Although the man to kill animals for food, the reproductive function of these will result in animals there are always available toman.
Water is also the man uses a renewable resource, and that through the hydrologic cycle, water use now will return later to be used.
However, excessive use of renewable resources can produce adepletion thereof. Animals, for example, require a certain time to reproduce. If man does not respect this period, the animals can not reproduce and eventually extinguished.

Non-renewable resourcesare those whose refresh rate is zero or near to human perception.

It is called non-renewable resources to those who have required millions of years to form ores, for example, are non-renewablenatural resources. For their training have gone through millions of years and, once consumed, do not reappear.
Besides minerals, many natural resources that are not renewable. These include energy sourceslike coal, gas or oil.

These materials are essential today, because they make machines run large industries, are applied in the production of electricity and move vehicles that transport us fromone place to another.
Excessive consumption of these materials has led to the reserves at an alarming decline, raising the danger that in a few years have been exhausted on Earth both oil and coal.Faced with this problem, all the world's scientists have been mobilized in the search for new energy sources, namely natural resources other than coal and oil to be able to replace them in the near...
