RENEWABLE RESOURCES

These are commodities such as solar energy, oxygen, fishstock,etc that is replaceable providing that the rate at which they are extracted is less than the natural rate at which the resources renew itself. This is becoming an enormously important issue in enviromental economics, for example the overextraction of fish stocks, and the global risks of permanent water shortages resulting from rising use of ground water stocks.Finite resources cannot be renewed.For example with plastics,crude oil,coal,natural gas and other items from fossil fuels,no mechanism exists from fossil fuels replenishes them.
