The progress of human depends upon the exploitation of different natural resources. The utilization of soil, water, coal, electricity, oil, gas and nuclear energy is very important for the development of nation.
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.
Natural resource is defined as form of energy and or matter which is essential for the functioning of organisms, population and ecosystems. Natural resource refers to any form of energy or matter essential for the fulfillment of physiological, socioeconomic and culture needs both as undivided or a community.
The basic ecological variables – energy, space, ‘time and diversity are sometimes combined are called natural resources.
This natural resource is maintaining ecological balance among them. The natural resources include all the land, water, minerals, vegetation, wildlife and sceneries all of which remain useful to human society in one way or other.
Natural ecosystem preservation could be accomplished by maintaining abundance of nature, preservation of endangered species, keeping of biodiversity, and so on.
Recently there have been increasing reports about research of ecosystem preservation using remote sensing or G1S (Geographic Information Systems) spatial analysis.
Sustainable forestry could be achieved by correctly managing forest resources through replanting, conversation, and protection from fire, disease and pollution.
Instead of using individual cars to work we could use car pools, we could make an effort not to use our domestic appliances during peak hours, we could use public transport wherever possible and we could switch to alternative power use. We, each of us, can make preservation happen.
