Answer 1

WATER:

THE IMPORTANCE OF WATER

       With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water circulates through the land just as it does through the human body, transporting, dissolving, replenishing nutrients and organic matter, while carrying away waste material. Further in the body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular secretions.

       An average adult body contains 42 litres of water and with just a small loss of 2.7 litres he or she can suffer from dehydration, displaying symptoms of irritability, fatigue, nervousness, dizziness, weakness, headaches and consequently reach a state of pathology. Dr F. Batmanghelidj, in his book 'your body's many cries for water', gives a wonderful essay on water and its vital role in the health of a water 'starved' society. He writes: "Since the 'water' we drink provides for cell function and its volume requirements, the decrease in our daily water intake affects the efficiency of cell activity........as a result chronic dehydration causes symptoms that equal disease..."
Meaning of Land:

Economics is a science of everyday life. It has to use words of everyday language.

But it gives them a meaning of its own, sometimes narrow and at other times wide.

ADVERTISEMENTS:

The term ‘value’, for example, has been given a narrow meaning and ‘land’ a very wide one.

“By land is meant not merely land in the strict sense of the word, but whole of the materials and forces which nature gives freely for man’s aid in land, water, in air and light and heat.” –Dr. Marshall.
