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.
However unlike trees that are a renewable resource all these are non renewable. The reserves are finite and at some point in the future they will be depleted.
We need to first conserve what we have left and to do that the call of the day is to use these natural resources sparingly and responsibly. We must resort to the use of alternative forms of energy which will lessen the burden on our natural resources.
There are various forms of alternative energy available. Light from the Sun also called as Solar Energy can be converted into electricity. This solar energy could be...
