Importance of Water Recycling The Topic Water is one of the most important resource that both human beings and animals use abundantly. The abundant usage has made us to forget that water resource can be exhausted someday. Due to the changing climatic condition and lack of ground water resource, water become scarcer in the world day by day. Another important reason for the high demand of water is the growth in population and extensive water requirement in the field of agriculture and other industrial sectors. Water is not equally distributed around the world. When some part of the world get abundant water, other don’t. …show more content…
But at the same time the quality of recycled water is questionable. But many processes are studied and processed to achieve the desired quality for recycled water. According to Gupta & Ali, (2013) the United States used its first water recycling process in 1940 in steel industry and it is still on going today. Though water quality can be attained, some of the major concerns of people are on the subjects such as health, environment as well as the cost effectiveness for the water treatment …show more content…
Water contains many minute organisms and pathogens that can be harmful to humans. Though many disinfecting methods are done effectively many times recycled water contains toxic metallic ions which is cancerous. The selection of water treatment methods and its high initial cost is another major disadvantage of recycling. Many highly-advanced disinfection methods need advanced technologies. Unfortunately, many of these technologies are not available in every part of the world. Rain water harvesting is method that is used in many part of the world as a part of water recycling but the major disadvantage of this method is the quality of water over time. The rain water cannot be stored for longer periods of time and can get possibly contaminated (Carrey, 2011). Another major disadvantage is the energy consumption and financial challenge for water recycling process like desalination and membrane technology (Frérot and Gurría, 2011). Many people around the world still consider recycled water is unsafe and can create many health concerns. For example, the mayor of Toowoomba, an Australian city arranged an opinion poll in 2006 related to the use of recycled water. More than half of the population rejected the proposal due to their different perception on recycled water (Frérot and Gurría,
Water is essential in our everyday life. Water is one of the most important substances on earth. All plants and animals utilize water to survive. Therefore it is vital that there be clean water for our communities to utilize to survive as a whole. Unfortunately because of different determinants our source of water are not always safe to use. We happen to have to deal with contamination of drinking water. Contamination of fresh water used for household needs, including pollution of oceans, rivers, lakes and reservoirs. There are categories of the different contaminants that exist such as Physical contaminants, Chemical contaminants, Biological contaminants, and radiological contaminants ("Types of Drinking Water Contaminants | Drinking Water
According to the United States EPA, only one percent of all water on Earth is deemed suitable for human consumption. In a world with a continually-growing population in need of an ample water supply, the world's sources of fresh water are showing increased signs of overuse as they are emptied faster than they can be naturally refilled. In fact, over the past half-decade the demand for water has more than tripled as the watersheds across the globe have been devastated (EPA).
As we know that water is very essential for our lives. With the increasing population the demand of natural water becoming high as it is used for commercial, residential and industrial purposes and water resources becoming less day by day. Global warming and climate change is one of the main reasons of reducing the rainfall and we don’t know how badly it will affect our rainfall system in near future.
In our generation of new technologies and high civilization it is hard to believe that our World is in Water crisis. This crisis is affecting not only low-developed parts of the world but also it affects high-developed countries, about one third of the humanity suffers from the scarcity of water (Molden 2010). One of the main causes of it is overpopulation. In increasing water demand water sources which we have now are not able to renew themselves. Another factor of water scarcity is not economized water consumption. Nowadays most of countries are beginning to realize that solving the problem of scarcity of water is very crucial. One of them is Mexico where water shortage is the national problem.
Most people in America find themselves drinking a nice glass of water that has a clean and refreshing taste to it. Most people do not have the privilege of drinking safe water. Contaminated drinking water has been linked to illnesses and deaths within the United States each year. We can solve this problem by finding new ways to clean water such as filtration and using diluted chlorine. Using these methods can lead to a much healthier way of living for those who suffer from contaminated drinking water in the United States. Contaminated water can be classified as water that contains pathogens, mercury, and even arsenic.
Growing Population, climate change, increasing water demands, drought, and impaired water quality render water supply a critical issue across the world. More than 1 in 9 people around the world, about 750 million, do not have access to safe, clean drinking water, and the problem is expected to worsen. In many parts of the world, water use is linked to energy use and greenhouse gas (GHG) emissions (any gaseous compound in the atmosphere capable of absorbing infrared radiation, thereby trapping heat in the atmosphere ultimately leading to global warming) because most water is transported hundreds of miles from sources to users.
The blame for Americans naturally waste fresh water every day is not an individual 's fault, but the fault of a culture, those before us, and the American society. Americans are not taught by society to save water, but are only taught by parents to save fresh water. Since most Americans are comfortable with the fixtures and appliances that they grew up with, they blindly use them without the understanding of the fresh water that is wastefully used. It is not the fault of Americans that buy the cheapest appliances, which often use more water than needed, that fresh water is being wasted every day. Americans have much to learn about how to save fresh water and how to teach others the importance of saving fresh water in homes across the country.
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.
This water has been cleaned from bacteria and so on. This water is from reservoirs filled by the rain and ground water. It does cost much work to bring the water into my home. The used and dirty water from my home goes back into this cycle after a recycling
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.
Have you ever wonder what can you do about the bottles and cans you find around you? People that doesn?t care about the world being clean is littering the place. It makes things very difficult to put up for. Recycling cans and bottles can help save the earth form waste and trash buildup and can make new things. I think that recycling should be mandatory and there should be recycling cans in various locations at school and everywhere else.
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.
Freshwater in the world makes up only a small portion of the 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.
Recycling is of great importance, and its importance is economic and environmental. It preserves natural resources, reduces depletion, reduces the amount of waste, reduces its growth, conserves the environment, cleanses it of some harmful waste, reduces unemployment and creates opportunities. New work.
Water is an integral part of not only human beings but all other creatures in the world. We use it every day for different purposes such as domestic, agricultural and industrial. Water has always been a prestigious resource. However, the majority of people do not appraise water’s worth since they do not face water scarcity; whereas, in third world countries it is one of the most serious problems. Nearly 2.4 billion people have a lack of water resources in the world, shows the investigation done by the Pacific Institute, an Oakland, California-based non-profit scientific research group. Moreover, every year this number is growing gradually and more people are suffering (Bloomberg News, 2010). There are certain causes which deteriorate current situation. The most influential reasons are global warming, pollution by human-beings and overpopulation. It is known that India is one of the countries which face water scarcity so this essay will consider the possible ways of solutions of water shortage in India.
