Introduction
The importance of water, in relation to the Earth and its inhabitants, can only be rivaled by the importance of oxygen. Living things depend on water in their habitat. However, the abundance of water is not as important as the usefulness of the water. Much of the Earth is made up of this unique liquid combination of hydrogen and oxygen, but the amount that can be used for human consumption is less than one percent (Boland, 2003). In essence, humans use potable water, water that is suitable for drinking and cooking, to satisfy their basic needs. Drinking (potable) water is free from poisonous substances, contaminants, and disease-causing organisms, which would be unsafe for human consumption (Gulflink).
In pre-historic times, inhabitants understood the importance of water sustainability for survival of the population. In ancient civilizations, water sustainability and potable water were both emphasized as ideals for the progress and continuity of the societies. Today, humans continue to progress in their understanding and utilization of technological processes to develop potable water. As a result, water filtration, water management, and water conservation efforts are becoming more effective and commonplace. Thus, as the technology continues to improve the quality of water as a resource, we cannot forget the basis to which past cultures had accepted: the continual existence or sustainability of this limited resource.
Abstract
A Historical Perspective
Man’s existence relies on water, and he cannot survive for more than seven days without it. M.N. Baker, a water quality historian, states, “In the earliest days of the human race, water was taken as found. It might be pure and abundant, plentiful but mud...

Canada's West coast was largely unprotected before the Great War. Although Japan, an ally of the British Empire, was tasked to protect the northern Pacific, the stationed Royal Navy -- and later the Royal Canadian Navy -- units at Esquimalt (RCN's only West Coast Base) in BC units was virtually nonexistent. The aged cruiser HMCS Rainbow lay at the harbour, and the two nearest sloops were the Shearwater and Algerine. It was known at the time that two modern German Cruisers, Leizig and Nurnbeg, was stationed in the Pacific, specifically by the West Coast of Mexico; some local sightings affirmed their proximity even closer to the Canadian West Coast.
Before this book was written in it's time frame, Holden deals with some struggles that change and impact his life quite a bit. The author portrays Holden's personality through his actions for the audience to understand him. Some of the actions are going back to visit the museum, calling and visiting Phoebe at home, visiting the park, keeping Allie's baseball mitt, wearing the red hunting hat, and asking about the ducks. These examples all play a part in showing that Holden is afraid of change. Holden is starting to grow up and make the transition into an adult, but the audience can tell Holden is struggling. Holden's decisions such as smoking, drinking constantly, buying a prostitute, and staying out late at night show his attempts to face adult life. However, when faced
Holden is one confused kid trying to beat the Man in the 1950’s. He grew up ignored by his parents, drifting from school to school in search of a purer lifestyle. On page one Holden humbly describes his lousy growing up. “If you really want to hear about it, the first thing you will probably want to know is where I was born, and what my lousy childhood was like…but I don’t feel like going into it, if you want to know the truth…that stuff bores me.” Holden does not want to go into his childhood and play the victim. He tells us that he had a rough time and leaves it at that. Later in the book he alludes to how his parents just shuffled him from school to school hoping that he would do better at the next one. All he tells us about is his dad is that he is a big shot corporate lawyer, not much about what kind of father he was. Suggesting that he was gone a lot and not around to give a good role model for Holden. In turn it shows up in Holden’s attitude towards adults.
In the book, Holden says his parents are “grand people”. That shows that he can’t be the son they take him to be. He is also unable to connect with his parents. He adores his brother D.B.as well as his sister. He explains himself to be the outcast. But, he also goes to say how he thinks his brother has sold his body for money, showing how immature and irrational he can think. The relationship with Holden and his father isn’t like most relationships. His father has higher expectations for Holden, as any parent would, such as passing all of his classes, which Holden has not done. Holden rebels a lot against his parents. Holden fears his parents and that is a reason why he didn’t want them knowing he has been kicked out of school. Holden smokes cigarettes, which can show that he stresses. But, with the humor in the book, you wouldn’t pick that
He begins to own up to his mistakes and starts to build stable relationships with his peers. In a conversation with Phoebe Holden mentions that he wants to be a catcher in the rye, and save children from falling off the cliff. Being a catcher in the rye is a metaphor that represents Holden's dream of saving people and leaving a lasting mark on the world. “ I have to come out from somewhere and catch them. That's all I'd do all day. I'd just be the catcher in the rye and all. I know it's crazy, but that's the only thing I'd really like to be. I know it's crazy”(186). When we enter this point in the book we can really get a feel for how much Holden has matured as he has begun thinking about others and not just focusing on himself. Although Holden has progressed in his track towards maturity he still tends to sway away from maturity. Holden continues to impolitely disagree with others and argue his way to the top in order to achieve what he desires, “Daddy's going to kill you.” Phoebe suggests, then Holden comes right back and states “I don't give a damn if he does” (186). This example shows that Holden still has a fixed mindset on his ideas and doesn't allow for new thoughts to persuade him to change his opinions. This forces us to view him as immature as we do not see a man who is incapable of interchanging ideas with others and therefore unable to interact with his
For those who've never heard of the term PED's, Performance enhancing drugs are any supplements that are considered to allow one perform better in their respective sports ,such as anabolic steroids and HGH( Human Growth hormones). The effects of these supplements can range from expediting muscle to increasing one's stamina. PEDs began to become the center of controversy when the I.O.C set up a medical commission to oversee the fight against doping, which ultimately lead to the ban of PED's in professional sports. Stemming off from the I.O.C...
... fact he speak to a number of adults to answer his peculiar question and “touchy" topics. Most likely Holden’s parents are conservative folks that disapprove with Holden’s behavior. His parent weren't great at raising Holden because they weren't there for Holden's needs. All they did was send out Holden to a school for years rather than looking for a solution to his problem. Another observation, he doesn't want to go home after being kicked out of school, which is usually a place you want to go to because home is safe and comfortable but instead, brings Holden anxiety and distress. His trouble with his parents probably has to do with his younger brother's death, Allie. After Allie’s death, his parents probably put the rest aside to grieve his son’s death. The parents didn't realize that Holden was affected by Allie’s death and might of neglect him for years.
Water is one of the most critical elements in determining any form of life. All living beings depend on water and without it, all forms of life come to a dead stop. Since the beginning of human civilization, water has been a driving force in how people dictate the affairs in their lives. People move near it, when there is too little of it, people flee from it, when there is too much of it, and people fight over it, when there is nothing of it. Our lives depend on water. Indeed, Vitruvius states in his De Architectura, “Water is indispensable for life, for pleasure, and for daily use.” In the Roman Empire, Roman citizens prided themselves as having the capacity to virtual supply of unlimited water. The Romans achieved this supply by constructing the aqueduct. As a symbol
The fact that water is necessary for survival makes it a key part of cultures. All major civilizations developed around a large source of water. This allows for agriculture, trade, transport etc. The benefits are numerous and as a result allow for population and economic growth. For human beings, water was not merely a substance that sustained life. It was above all an elemental ingredient in the way people conceived of the world and
Providing extremely fertile soil is one, if not the most important, roles the Nile River played in the life of the ancient Egyptians. By providing fertile soil, the Nile made it easy for cities and civilizations to grow alongside the banks of the river. This fertile soil comes from the annual flooding of the Nile. This replenishes the top soil with silt deposits that hold much needed nutrients for crops to grow. Ancient Egyptians developed highly complex irrigation methods to maximize the effect of the Nile waters. When the Nile overflows in mid summer, Egyptians divert the waters through the use of canals and dams. As the water seeped into the farm land, rich deposits of silt ensured a good harvest for the year. This allows the civilizations of Egyptians to grow enough food to feed the community. Without the annual flooding of the Nile, Egyptians would have a very difficult time growing necessary amount food to sustain life. Most of the land in the Egyptian nation is dry desert. Very little rain falls year round here. The river provides the needed water to grow the crops as well as provide drinking water for the people. Th...

Water is the most utilized substance. There is not one person, or industry that could survive without water. Water provides in more ways than just quenching thirst. This is why the most critical issues today, revolve around water loss. It may come as a surprise, but according to Patricia Lefevere, only one percent of the water on earth is useful to humans. The other 99 percent is not accessible or fresh (Lefevere). However, the problem is not as terrible as it seems. According to The Economist the main problems are; how much water is too much, and the way the water is used (Sin aqua non; Water). Water is a valuable resource; without knowing how much fresh water can be taken from sources without them being depleted causes an uncertainty to

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.
Water is an essential nutrient that our body requires every day. Without water human life cannot be sustained. Water deprivation kills faster than lack of any other nutrient. People do not think of water as a nutrient and don’t realize the important role of water in the body functions.
