| + | ===== 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: | ||
