Natural resources can be broadly categorised into renewable and non-renewable resources.
Renewable resources are those which get renewed or replenished quickly. Some of these are unlimited and are not affected by human activities, such as solar and wind energy. Yet careless use of certain renewable resources like water, soil and forest can affect their stock. Water
seems to be an unlimited renewable resource. But shortage and drying up of natural water sources is a major problem in many parts of the world today.

Non-renewable resources are those which have a limited stock. Once the stocks are exhausted it may take thousands of years to be renewed or replenished. Since this period is much more than human life spans, such resources are considered non-renewable. Coal, petroleum and natural gas are some examples. The distribution of natural resources depends upon number of physical factors like terrain, climate and altitude. The distribution of resources is unequal
because these factors differ so much over the earth. .

Human Resource refers to the number (quantity) and abilities (mental and physical) of the people. Though, there are differing views regarding treatment of humans as a resource, one
cannot deny the fact that it is the skills of human that help in transferring the physical material into a valuable resource.
