A resource is a source or supply from which a benefit is produced and that has some utility. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. Examples of non renewable resources are coal, crude oil etc. Examples of renewable resources are air, water, natural gas, wind, solar energy, etc. They can also be classified as actual and potential on the basis of level of development and use, on the basis of origin they can be classified as biotic and abiotic, and on the basis of their distribution, as ubiquitous and localized (private resources, community-owned resources, natural resources, international resources). An item becomes a resource with time and developing technology. Typically, resources are materials, energy, services, staff, knowledge, or other assets that are transformed to produce benefit and in the process may be consumed or made unavailable. Benefits of resource utilization may include increased wealth, proper functioning of a system, or enhanced well-being. From a human perspective, a natural resource is anything obtained from the environment to satisfy human needs and wants.[1] From a broader biological or ecological perspective, a resource satisfies the needs of a living organism (see biological resource).
