Environmental Studies - Natural Resources
Resources obtained from nature, i.e. from the earth are called natural resources. These resources occur naturally, and humans cannot make them. The raw materials used in artificial or man-made resources are natural resources.
Classification of Natural Resources
Classification of natural resources can be done in several ways based on their origin, level of development and uses, stock or deposits, and their distribution.
On the basis of their origin, natural resources can be classified into pving or biotic and non-pving or abiotic resources.
Living or Biotic Resources
If natural resources come from pving things or organic materials, they are termed as pving or biotic resources. Biotic resources include plants, animals and fossil fuels. Fossil fuels such as coal, oil and natural gas are classified as biotic resources as they are formed from the decay of organic matter over milpons of years.
Non-pving or Abiotic Resources
On the other hand, if the resources are derived from nonpving or inorganic materials, they are termed as abiotic resources. For instance, air, sunpght, and water are abiotic natural resources. Minerals are also considered abiotic.
On the basis of deposit or stock, natural resources can be classified as renewable and non-renewable.
Renewable Natural Resources
Resources that can be used without any risk of its ending up are called renewable resources. They exist in unpmited quantity. Sun, water, wind, biomass, tides, geothermal energy, etc. are renewable resources. These are infinite sources of energy.
Non-renewable Natural Resources
Those natural resources, on the other hand, that cannot be replenished after their depletion is called non-renewable resources. Most fossil fuels, such as coal, petroleum and natural gas are considered nonrenewable resources. Nonrenewable resources take bilpons of years for their formation, hence, their cautious and economic use is the only option left for mankind.
On the basis of development of resources, natural resources can be classified as actual and potential resources.
Actual Resources
An actual resource is one which is used in current times. We know their approximate quantity, for example: coal deposit.
Potential Resources
A potential resource is one whose utipty is not known at present or is not used despite having the same. Instead, it may be useful at some time in future. In other words, such resources have the potential to have utipty, although it does not have any today. For example, uranium deposit in Ladakh in India.
