Soil, wood, oil. minerals, petroleum, water are considered natural resources because they occur in their natural form and are not made by human beings.
Humans can only modify natural resources. The energy that makes natural resources comes from geochemical, geophysical and solar energy.
The exploitation of nature and natural resources can be dated back to the advent of humankind and the very start of civilization. Earlier people used to cut trees for fuel, for building materials for boats and for shelter. There are two kinds of natural resources- renewable and nonrenewable.
Wood which is one of the main natural resources has the advantage of being renewable. Fish, animals and forests can renew themselves if they are not over-harvested. Forests can be replanted and, in time, the wood that was used can be replaced.
However in recent times, we have been witnessing the cutting down of trees at alarming rates. In cities it is becoming, increasing difficult to see a green patch. If we do not replace these trees at the same speed as we are using them then very soon this resource will be expended. The cutting of trees also results in loss of ecosystems and soil erosion, and less rainfall. When fossil fuels were discovered they momentarily took the pressure off wood.
First there was coal, then oil as in crude oil or petroleum and then later petrol and more recently natural gas.
We must all join hands in our efforts to preserve our natural resources. Preservation cannot happen without conservation; hence we must all do our part in conserving.
