 +===== Difference Between Natural Elements and Natural Resources ===== 
 + 
 +Natural elements are elements that are provided by nature without human intervention,​ like the wind and the water.  
 + 
 +Natural resources are those natural elements that can be used by us. For example, we can drink water and use the wind to produce energy.  
 + 
 +There are natural elements that cannot be considered natural resources, like ore that is inaccessible to mankind.  
 + 
 +We have created the following plot to show that natural resources are a subset of natural elements:
