Throughout history, man has used his knowledge
ments of the natural environment and the tools available for
extract and transform the elements of nature who serve him
to meet your needs. For example, since ancient times
rocks and spears to hunt and get food are used, the mattock
to till the land, and axes to cut wood from AR-
boles and make homes against the cold.
Currently, worldwide, people are engaged
various activities, such as mining, fishing or aprovecha-
tion of forests; of these activities obtain resources
natural (minerals, fish and trees, respectively).
When the elements are used by being
human to meet specific needs are known as
natural resources
; they acquire importance according to the
needs you meet; for example, in cold areas,
the skins of animals have great value because they become
in clothing.
Some resources are consumed or used directly from the
nature (in the case of water, solar energy, or the fruits of
trees), but others can not be consumed directly and
They must be transformed through human labor.
These transformed resources are known as
matters first
but
and they are used to manufacture more sophisticated products:
combed cotton, spins and weaves to produce fabrics; wheat is milled
flour for bread and produce.
Although much of the natural resources is recoverable
after some time, often they are extracted
as much of what nature can produce, it
It is reflecting not responsible for extracting form. So it is
important to consider the recovery time of each
resource, to avoid the risk of running out.
