Natural resources are utilized by human beings either directly or indirectly for survival. The examples of natural resources are air, soil, water, sunshine, coal, plants, animals, and minerals. Additionally, nature acts as the sole provider for our fundamental needs which includes food, clothing and shelter.

Everything we utilize in our day to day lives is drawn from the available natural resources. Besides, the artificial resources are derived from the available natural resources. However, we never think that these resources might get depleted eventually if used irresponsibly. The surging global population, rapid urbanization and industrialization have created an increased demand on the available resources.
