A natural resource is
anything that people can use which comes from nature. People do not make natural resources, but gather them
from the earth. Examples of natural resources are air, water, wood, oil, wind energy, hydro-electric energy,
iron, and coal.
We often say there are two
sorts of natural resources: renewable resources and non-renewable resources.
A renewable resource
grows again and comes back again after we use it. this is like a rebounding
ball . For example, soil, sunlight, water and wood are renewable resources.
A non-renewable resource
is a resource that does not grow and come back, or a resource that would
take a very long time to come back. And this one is like a sin once done
is done. For example, When we use coal, there is less coal afterward. One
day, there will be no more of it to make goods. The
non-renewable resource can be used directly (for example, burning oil to
cook), or we can find a renewable resource to use (for example, using wind
energy to make electricity to cook).
It is important to conserve (save) non-renewable resources, because if we
use them too quickly there will not be enough.
Most natural resources are
limited. This means they will eventually run out. A perpetual resource has a
never-ending supply. Some examples of perpetual resources include solar energy, tidal energy, and wind energy. Other examples are salt,
stone, magnesium, and diamonds.
Some of the things influencing
supply of resources include whether it is able to be recycled, and the availability of suitable substitutes for the
material. Non-renewable resources cannot be recycled. For example, oil,
minerals, and other non-renewable resources cannot be recycled.
The demand for resources can change with new technology, new needs, and new economics (e.g. changes in cost of the resources). Some
material can go completely out of use, if people do not want it any more.
Demand of natural resources is very high, but availability is very low .
All places have their own
natural resources. When people do not have a certain resource they need, they
can either replace it with another resource, or trade with another country to get the resource. Some resources
are difficult to find, so people sometimes fight
to have them (for example, oil resources).
When people do not have some
natural resources, their quality of life can get lower. So, we need to protect
our resources from pollution. For example, when they can not get clean water,
people may become ill; if there is not enough wood, trees
will be cut and the forest will disappear over time (deforestation); if there are not enough fish in a sea, people
can die of starvation. Some examples of renewable
resources are wood, solar energy, trees, wind, hydroelectric power, fish, and
sunlight. So humans should begin saving their natural resources. Or else, all
will be lost and it will be difficult for humans to survive
