A renewable resource is an organic natural resource which can replenish to overcome usage and consumption, either through biological reproduction or other naturally reoccurring processes. Renewable resources are a part of Earth's natural environment and the largest components of its ecosphere . A positive life cycle assessment is a key indicator of a resource's sustainability.
Definitions of renewable resources may also include agricultural production, as in sustainable agriculture and to an extent water resources . In 1962 Paul Alfred Weiss defined Renewable Resources as: " The total range of living organisms providing man with food, fibres, drugs, etc... ". Another type of renewable resources is renewable energy resources. Common sources of renewable energy include solar, geothermal and wind power, which are all categorised as renewable resources.
Water can be considered a renewable material when carefully controlled usage, treatment, and release are followed. If not, it would become a non-renewable resource at that location. For example, groundwater is usually removed from an aquifer at a rate much greater than its very slow natural recharge, and so groundwater is considered non-renewable. Removal of water from the pore spaces may cause permanent compaction ( subsidence ) that cannot be renewed. 97.5% of the water on the Earth is salt water, and 3%
