Recommended: Issues on water scarcity conclusion
Water resources occupy a special place among other natural resources. Water is the most widely distributed substance on our planet: albeit in different amounts, it is available everywhere and plays a vital role in both the environment and human life. Of most importance is fresh water, Human life itself is impossible without it because it can be substituted by nothing else. Human beings have always consumed fresh water and used the various natural surface water bodies for a whole range of purposes. For many hundreds of years man’s impact on water resources was insignificant and entirely of a local character. The magnificent properties of natural waters - their renovation during the water cycle and their ability for self-purification - allowed …show more content…
In many parts of the world the unfavourable results of man’s long-term - often unreasonable - activities, have now been discovered. This concerns both the direct use of water resources and also the surface transformations that have taken place in many river catchments. To a large extent this has been due to a drastic increase in global water withdrawal since the 1950s. In turn, this increase was caused by the scientific and technological revolution which permitted the intense development in production capabilities in all spheres of the world economy. Compared with previous decades, annual water withdrawal during 19.51-60 increased fourfold. This occurred because of the dramatic expansion in irrigated areas, the growth in industrial and heat and power engineering water consumption, and the intensive construction of reservoirs in all continents. All over the world during the last 25-30 years there has been a massive anthropogenic change in the hydrological cycle of rivers and lakes, affecting their water quality, their potential as water resources and the global water budget. The extent of water resources, their spatial and temporal distribution, are determined not only by natural climate variations as previously, but now also by man’s economic activities. In many parts of the world water resources have become so depleted and much contaminated that they are already unable to meet the ever increasing demands made on them. This has become the main factor impeding economic development and population
Water is the foundational basis of life on Earth. Ecosystems, society and humans are completely dependent on it, and as the world population continues to grow, there will be more mouths to feed, and those people will need water to continue their daily lives. However, shortages and poor management leads to the destruction of natural habitats and human suffering. Desertification of land in China is ever-increasing, turning green, lush land into desert. However, this is due mainly in part, because of human activity, and global warming (Wang, Yang, Dong, & Zhang, 2009). The United States could experience a crisis similarly to China’s, but for now they have averted such a catastrophe, because of heavy regulation of water. Though there are water shortages in many parts of the world, it is unwise to export water from the Great Lakes to those regions. Two major reasons why diverting the Great Lakes is a terrible idea, one: it allows for waters wars to start on the basis of who is allowed to access it and for commodification purposes. Two, diverting water on such large scales could have cataclysmic effects on the local residents as well as the environment.
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
In the World, the liquid medium that we know as water is the main component that keeps humans, animals and their respective ecosystems alive. Everything from trees down to the smallest leaf requires it, and it is required for any lifeform to continue to grow. Though as humanity expands and continues on an upward slope, humans as a lifeforce continue to need more. Water is a defining aspect of a community, and with the ever-rising population and human-crafted climate change coming to an all-time high, one of the most important water origins of the southeast region is coming to a very dangerous low.
Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global scale. If our greed comes before companionship, and our quality of life is more important than pollution, then our future generations to come will be born into a world of chaos, and a scarce of a basic human necessity.
Growing scarcity in nearby water resources is the issue addressed in “Will Water Become the Chief Commodity of the 21st Century?” by Christa Marshall. The thesis of this essay is will water become the chief commodity of the 21st century? The author’s main claim is the world faces a growing number of challenges surrounding water and her sub claim is these examples underscore the many options available to alleviate a growing global water crisis. The author argues where water demand will exceed available supplies could rise forty percent. Her conclusion is businesses need to gain a better sense of how much water they are actually using.
Water is an essential part of life for any living organism in the world. People use water every day to drink, do daily housework, or to bathe in; while animals use water to survive. Because of the doings of humans, the water that is so essential to all organisms’ well being is being polluted. The water drink and use every day may have oil from large petroleum companies spilling into it. Debris from sewer plants float into the ocean when they overflow. Even prescription pills are contaminating the water. Not only is the water affecting the humans that drink it but also affects the aquatic life. Aquatic species may have problems reproducing which disrupts the whole food chain and biodiversity web of life. How water becomes contaminated should
This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
Change an Old Showerhead: Something as simple as swapping an inefficient, outdated showerhead with a new, droplet saving showerhead can make a big difference in conserving water. A droplet saving showerhead can use up to 2900 gallons less water per year. Changing a showerhead is relatively simple. Begin by plugging the drain in order to prevent small parts from slipping down the drain. Next, use a wrench to twist off the threaded ring that attaches the showerhead to the spout. Next, wrap a few layers of thread seal or plumber’s tape around the threads on the spout. Then, screw on the showerhead and tighten it with a wrench. It is now ready to use and conserve water.

People don’t appreciated the many advantages that comes with having clean potable water to use, taking it for granted. A lot of clean useful water is wasted by humans all the time that people don’t care about saving water because they have easy access to it. Clean and safe drinkable water resources are getting scarce as the population grows. The world is facing many problems, but the most important needed to survive, is water. Water is getting low in many countries, therefore habitants are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages; meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands. Water shortage affects the agricultural sector, so as a consequence the price for production
The quality of water is the main source to all of the roles that water play in our lives. From the beauty of nature’s waterways connected with wildlife, to the important lives that clean rivers and streams support, to the important role that safe water plays in drinking water and health good water quality is basic to all the networks of life and livelihood that water supports. Water is the source of life on the planet earth, and human civilizations blossomed where there was reliable, compatible and clean freshwater. Use of water by humans for drinking, washing, cleaning and recreation requires water free from biological and physical sources of contamination. Plants, animals, and the habitats that support biological diversity also require clean water. Water of a certain good cheaper quality is needed in all scenarios of the world like to grow food, to power cities, and
Freshwater in the world makes up only a small portion of water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only <1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes. Many of these in later years shall need to be addressed as tension rises:
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.
Water is the most priceless resource on our planet. Billions of gallons flow through our rivers and lakes. Millions of gallons are consumed by humans each day. Our world’s surface is seventy percent water. With so much water around us, how can 1.1 billion people still lack access to clean water (Cooper, Water Shortages)? People are already using fifty four percent of all the freshwater available on this planet (Cooper, Water Shortages). We cannot afford to neglect something so essential to our very survival. We must defend our most important natural resource—water.
The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
