Exhaustible resources are of two types: Renewable and nonrenewable.
Renewable resources: They are exhaustible natural resources which get replenished, recycled or reproduced and can last forever provided they are not used beyond their renewability. it include biotic and abiotic resources.
Nonrenewable resources: They are exhaustible natural resources which can not be gained or reconstructed once they have been used up due to lack of recycling or regeneration.
Renewable resources:
- They are exhaustible resources which get regenerated or recycled
- Renewable resources can last forever if used judiciously
- Availability can be increased by enhancing their renewability without causing depletion.
- They include edaphic resource (soil or land), water resources and biological resources or bioresouces (living organisms and their products-agriculture, aquaculture, poultry, livestock etc),soil fertility, forests, underground water etc
Nonrenewable resources:
- Nonrenewable resources are exhaustible resources which do not get regenerated or recycled
- They are going to get exhausted sooner or later whether or not used judiciously
- Availability can be increased only by increasing their extraction but it will cause early depletion.
- Fossil fuels (coal, lignite, petroleum), Mineral deposits, metals, natural gas are examples.
