Recommended: 5 key causes of water scarcity
Each day, over 5,000 children die from diarrhea-related diseases developed from unsafe drinking water. Approximately one billion people do not have access to clean drinking water; one billion people about equates to one out of every six individuals. The deaths resulting from unsafe drinking water are greater than the number of deaths caused by war. We all must work together to find new sources of freshwater so that everyone in the world will have adequate supplies of safe drinking water. This essay will outline current and future technologies that will be available to resolve this problem in the coming years.
Water covers nearly three quarters of the Earth, yet people still die everyday from the lack of fresh water. How is this possible? Only three percent of the planet’s water is fresh water, and a small amount of that constitutes water not found in snow or ice. Depletion of this fresh water is occurring at a faster rate than replenishment, creating a fresh water crisis. Experts from the World Health Organization (WHO) project that within 40 years, four billion people—nearly two thirds of the world’s population today—will face major fresh water shortages. This problem cannot be solved by any one group of people, yet at the heart of the matter lays engineering. Engineers need to optimize current technologies:
1. Desalination of ocean water
2. Diversion of water
3. Recycling of wastewater/irrigation
Also, engineers need to continue to develop new technologies. New projects on the horizon of fresh water engineering include:
1. Nano-osmosis of ocean water
2. Decentralized distillation units in rural areas
3. Strategies for reducing water use
Desalination of ocean water presents enormous challenges w...

...Much of this explosion in population will occur in regions considered to be “third world.” Fresh water is scarce in these regions today; in 2050 the lack of fresh water in these regions could reach disastrous levels. The implications of these numbers greatly weigh on the shoulders of engineers. Lack of fresh water cannot be ignored requiring the further development of technologies and programs aimed to solving the problem. This problem has implications socially, politically, and scientifically. Engineers alone cannot be tasked with solving the problem, yet their work will greatly aid the progress towards developing a solution.

“Water is needed for all living things. Water is our planet’s most precious resource. It is required by every living thing, yet a huge proportion of the world’s population struggles to access clean water daily.” (Feldman, 2012)
Throughout the path of human and mammal history, there have been a small number of characteristics in life that are needed to maintain and facilitate survival. These necessities consists of water, nutrition, shelter and oxygen, which many historians, anthropologists and humans in general have began to realize. Through this realization, one apprehends the fact that out of the four requirements of life, water by far provides as the most important. Each year, the world population increases exponentially; today being over seven billion. Due to this increase human beings have begun to experience a serious crisis dealing with the loss of water. The world has become limited with its supply of water, due to its high demand. Humans believe water is a resource that is completely renewable and everlasting, but through many years water supply is becoming extremely scarce. Statistically proven there is only " 2.5 [percent] which is freshwater. Almost all of it is locked up in ice and in the ground. Only a bit more than 1.2 [percent] of all freshwater (which was only 2.5 [percent] of all water) is surface water, which serves most of life's needs (The World's Water). Water, on a daily basis, is wasted through many daily activities such as people utilizing water in their houses, at work and tremendously through gardening. People cannot live without water, but many do not understand how much water supply around the world is potable. Many countries around the world do not facilitate clean water, usually consisting of dirt and bacteria, which makes many people ill. The polluted water is usually in the rural and poor countries, that do not have enough money and technology to provide hygienic water. Contaminated water broadens the s...
2.1 billion people in countries that are undergoing a form of urbanization have inaccessibility to clean drinking water as a result of pollution, poverty and poor management of resources. Water resources are being depleted by agriculture and energy production
Water is a crucial element for human survival and plays an important role in reducing deadly diseases and improving the human health [1]. As the global population increases, there is an increasing demand for clean water supply [1]. However, according to WHO and UNICEF, around 2.1 billion people lack access to safely managed drinking water services and 340,000 children under five die every year from diarrheal disease [1]. It is crucial to take actions in addressing the global water crisis to satisfy basic human needs and growing demands on world’s water resources for other water uses.
The average human can not live any longer than three days without water. Many of the world’s fresh water sources are running dry or are being contaminated, particularly in developing nations, leaving many without safe water to drink. Only two and a half percent of the Earth’s water is freshwater, and less than one percent is accessible by humans (not tied up in ice caps). This one percent of the Earth’s water supply is expected to sustain a population of over 7 billion people, each needing 2.6 liters a day to remain fully healthy, plus all of the water required for agriculture and industry. These scenarios will only become more and more prevalent as time moves on and we consume more water. The United Nations has classified our planet as being in the midst of a global “water crisis.” Global water supply and shortages are becoming an incredibly real and serious issue, and planning for the future is key to preventing population decline due to a lack of safe drinking water. Shortages of drinking water lead to wars and serious international conflict for basic human survival needs. One of the most popularly and commonly proposed solutions to this problem is to create seawater desalination plants to remove salt from ocean water to make it safe to drink. These water desalination plants, however, are not a viable option to carry us in to the future due to their potentially harmful impacts and expenses.
Water is a source that humanity need for both domestic and industrial use and is utilized in a huge amount. Thus, there is a pressure on water. The increase of population and the industrial development of the majority of countries aggravate the problem. The excessive consumption of water coupled with the scarcity of this resource makes the issue even more critical. According to Lefort, water covers around 70 percent of the Earth, freshwater makes up only 3 percent of it, moreover, almost all of that is unattainable to use. (Lefort, R.,1996) Generally, only about 0.01 percent of the world’s total water supply is considered available for human use. What is more frustrating is that only a few sources of fresh water can be relied
Water is vital for all life on planet. It assumes a crucial part in our wellbeing, economy, food production and environment. 750 million individuals around the world need access to safe water; roughly one in nine individuals. Water is fundamental for all people to survive. A few of us have admittance to water and underestimate it. A considerable lot of us can stroll to a supermarket and purchase filtered water or we can simply go into our kitchens or bathrooms to get water from a tap. There are numerous more in this world who don't have this sort of extravagance. There are billions of individuals being affected by a water emergency. About one billion people have no entrance to clean, drinkable water. What's more 2.5 billion individuals don't
Most people never give attention to the importance of water or the purity of what is provided. Water is a universal necessity, which is becoming a crucial issue in insufficiency. The deficiency is a global crisis around the world, and leads to many detrimental effects. The lack of water affects the entire continent without worldwide knowledge. Water is used in almost every entirety of human life; the careless usage causes profuse issues for living. There are several resources that provide the necessity of water, which are in poor situations in provision. Water scarcity is rapidly becoming a global crisis that is often neglected, but the driving forces, the consequences, and the ability to reduce the problem are crucial to assert.
A world with an extreme water crisis is not a far-fetched thought, especially well into the future like the year 2116. A study group at the Massachusetts Institute of Technology expect “5 billion (52 percent) of the world’s projected 9.7 billion people to live in water-stressed areas by 2050”, and coupled with a larger
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:
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.
Water is a foundation for life on earth. Water is necessary for us to drink, bathe, cook, wash dishes, to manufacture, and so on. Even the human body is composed of 65% water. Almost everything we do involves the use of water, and yet, only 3% of the earth’s water is fresh water; and only one third of the freshwater is readily available for use. This small fraction supports all life on land. We rely on clean water to survive, but patterns of climate and human activity are threatening our clean resources of water. We are using water at a rate faster than it precipitates to the ground. We mistreat the small fraction of water that we have. Not only are human beings at risk, but also the whole ecosystem is suffering. Human patterns are drastically affecting the rate of climate change. More than one billion people cannot get safe drinking water. This has to do with politics, infrastructure, and sustainable use. Clean water is being affected by degradation, climate extremes, and new climate patterns.
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
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.
