“Nary a drop to drink”
Water is a natural resource which is very critical to all life on Earth. Natural resources are things that come from nature. Natural resources are either renewable or non renewable. Some of the Earth’s natural resources are; Soil, Air, and Water. Although the Earth is almost covered in water, it is considered a finite resource which means there is an end to the amount of water that is available for human consumption. Where a population lives and also their quality of life, depends on the availability of potable water. This is so because; of all the water on the Earth’s surface, only about one percent is fresh water that is available for human use. Fresh water is found in rivers, streams, lakes and underground aquifers. Global water consumption is on the rise with the increase in the world’s population and industrialisation. This gives rise to water constraint whereby there is a shortage of water to meet the needs of people. More than one-third of the world’s population live in countries that are facing water constraint. The following is a list of ways water is used for human consumption. Ten main uses of water
1. Commercial water use refers to fresh water used in motels, hotels, restaurants, office buildings, other commercial facilities, and civilian and military institutions. The restaurant industry is a major source of commercial water usage. 2. Domestic use refers to water that is used in the home every day, for purposes, such as drinking, food preparation, bathing, washing clothes and dishes, flushing toilets, and watering lawns and gardens. 3. Industrial water use is an important resource to a nation's industries. Industries use large amounts of water for steel, chemical, paper, and petroleum refining. This water is often reused over and over for more than one purpose. 4. Irrigation water use is water artificially applied to farm, orchard, and pasture, crops, for frost and freeze protection among other uses. Irrigation is the largest category of water use worldwide as almost 60% of all the world's freshwater withdrawals go towards irrigation uses. 5. Livestock water use refers to fresh water utilized for stock animals, feed lots, dairies, fish farms, and other nonfarm needs. 6. Mining water use is used for the extraction of naturally occurring minerals; solids, such as coal and ores; liquids, such as crude petroleum; and gases, such as natural gas. 7. Public Supply water use is the provision of water by public utilities, such as county and municipal water works. It is then delivered to users for domestic, commercial, and industrial purposes. 8. Thermoelectric Power water use is the largest use of water worldwide. It refers to the amount of water used in the production of electric power generated with heat. 9. Aquaculture water use refers to water used for raising creatures that live in water for food, restoration, conservation, or sport. Sea creatures are grown in controlled feeding, sanitation, and harvesting procedures primarily in ponds, flowthrough raceways, and, to a lesser extent, cages, net pens, and closed-recirculation tanks. 10. Hydroelectric Power is an important source of renewable energy. It is an old method which represents 19% of total electricity production the world over. Hydropower plays a major role in reducing greenhouse gas emissions and the water used to operate it comes from nature as rainfall.
Our world without water
It is hard to imagine a planet such as ours with its abundance of life can exist without water. Three percent of the water that covers the earth is freshwater. Of that three percent only one percent can be used for the sustenance of human life. Sixty-six percent of the human body is made up of water and at just two percent dehydration, performance decreases by around twenty percent. The importance of water is recognized by the smallest child, animal or even plant. The extravagant use of water for...
