Below is an essay on the importance of water from anti essays, your source for research papers, essays, and term paper examples. The importance of water is clear to us, it has many ways to use and we can’t overlook it. The only time the urban folk become aware of the importance of water is when there is a drought and their water supply is regulated.

They may find themselves in a worse position than the rural man who may have a steady supply of water from his well. Water can convert whole, barren tracts of land into luxurious, rich and fertile regions, through the use of irrigation. In some parts of the country, diminishing quantities of rain have caused fertile land to dry up in the past years, creating barren deserts. Scientists find water the most fascinating fluid in the world because of its versatility and usefulness. Water is everywhere, it is very important for earth and every living things, including us.

The aim is to review the importance of water recycling and the unending effects of hard water all round us. Objective is to achieve a clear understanding of the present and future benefits of water recycling and why it is still practised today. The perpetual need for the various solutions in softening hard water is looked into retrospectively carefully highlighting typical problems likely to occur. Biological importance of water: water is a truly incredible molecule, biological life as we know it evolved from the water. It is the main constituent of all organisms and we humans are made up of around 70% of it. In order to understand why the water molecule is so important, we have to examine its structure. A molecule of water consists of two hydrogen and one oxygen atoms see diagram left.

Water is a polar molecule, and since it has two charges it is dipolar which means that it has negative ends oxygen and positive ends hydrogen as shown in the diagram. This dipolar quality gives an electrostatic, albeit weak, force and allows adjacent molecules to bond together resulting in water having a high boiling point. 160 160 160 160 160 160 160 160 160 water is an exceptional solvent in particular when dissolving salts, simple alcohols and sugars all otherwise known as polar substances. For example an ionic salt such as potassium chloride would dissolve because the charged particles ions will dissociate within the water. The positive ions attract to the negative oxygen atom and the negative ions to the positive hydrogen. 160 160 160 160 160 160 160 160 substances that are non polar however, for example lipids, do not mix with water and consequently can be easily separated from aqueous solutions.

For example, when droplets of oil merge in water they do not mix they are said to be immiscible and can easily be drained from the top surface of the water. Water based lubricating fluids within the body include: mucus this is used externally to aid movement in animals, such as in snails, or internally on the gut wall to aid the movement of food. Because of the structure of water, it is not easily compressed, making it a useful means of supporting organisms. Plants are also supported by the water that arrives due to osmosis into their cells. Within humans, the shape of the eye is maintained by the aqueous and vitreous humours within them.

The molecules in water are very cohesive sticky due to the hydrogen bonds within it see diagram. Water readily dissolves other substances and this attribute is used in transport through the body. Water is a fundamental component of blood plasma, tissue fluid and lymph and is used to dissolve a wide range of substances such as red blood cells that carry oxygen, as well as minerals, which can then be easily transported and made available to the cells. 160 160 160 160 160 metabolic waste products such as ammonia and urea are removed from the body in a water solution. This is because ammonia and urea are toxic when undiluted and by diluting them, they can be recycled more easily. 160 160 most digestive juices have salts and enzymes in solution for example tears. Tears consist largely of water, they are used for cleaning the surface of the eye to avoid infections.

160 160 160 160 160 160 160 160 within plant and animal reproduction cycles aswell, water is used as a means of transportation. In plants, the build up of osmotic pressure helps to disperse the seeds of some plants such as the squirting cucumber and the spores of mosses and ferns can also be carried by water. It is a raw material in photosynthesis, where energy from light is used to split water, removing hydrogen. As a coolant/ in homeostasis: because of its structure the strong attractions , water has a very high boiling and melting point in comparison to other molecules with a similar rmm.
