Natural Resources

The natural resources are of two types: renewable and nonrenewable. The difference between them is determined by the possibility for renewable use again and again, whenever aman takes care of regeneration.

Renewable Resources
Are natural resources that can be restored by natural processes at a rate similar to or greater than the consumption by humans. Solarradiation, tides, wind and hydropower are perpetual resources that they are safe to run out the long term. Renewable resources also include materials such as wood, paper, leather, etc.. if they areharvested sustainably.Recursos
non-Renewable
A natural resource is considered a renewable resource if it can not be produced, grown, regenerated and reused on a scale that can sustain itsconsumption rate. These resources often exist in fixed amounts or are consumed faster than nature could recreate them. It is called the contingent reserves of resources that can be extracted profitably.The economic value (money) depends on their rarity and demand and is a matter of concern to the economy. Its usefulness as a resource depends on its applicability, but also the economic cost andenergy cost of their location and operation. Some examples of non-renewable resources: oil, minerals, metals, natural gas and underground water tanks, provided they are confined aquifers withoutrecharge.

all of this, make us think about the care that the man should have when he explote the resources that the nature provides. What should every country do to solve the enviromental issues?Management of forests, soil conservation and reforestation
