Some possible contributing factors cannot always be ruled out but should be acknowledged by the researchers. The main emphasis of quantitative research is on deductive reasoning which tends to move from the general to the specific. This is sometimes referred to as a top down approach.
Water has been important for people for thousands of years. Without water there would be no life on earth. We use water in our houses for cooking, bathing and washing the dishes. Water is used to grow food. In many dry areas farmers must bring water to the fields through canals and expensive irrigation systems .
Water is also a living environment for many plants and animals. Air: Air is made up of several gases, but the two most important gases are Oxygen and Carbon dioxide. Without oxygen, animals will die, and without carbon dioxide, plants cannot survive. Food (nutrients): Living things need energy for function. Energy is needed to grow, reproduce, move, and to work.
