Water Shortage essays

Water Shortage essays Water shortage and degradation is a growing concern for many countries including the United States. Drinking water protection is a big responsibility that involves government, business and individuals. Everyone has an important role in trying to protect the supply of water. Water is a vital necessity that all people need in order to survive. Without water, people could only go a few days to a few months before having serious health problems or even death. One of the major concerns regarding water is if there will be enough water for the demand within the next 25 to 50 years. With the help of agencies, scientists and experts, we as people may see that there will be a shortage of water in the years to come. Today in the world the leading cause of the water shortage is the rising demand for water for the industries and agriculture (George, 1). On the earth today there is no more freshwater than there was 2,000 years ago. Then the population was 3% of what it is today (Knight, 1). In 31 countries around the world that contains near a half a billion people face water shortage with the most severe being in the Middle East and Africa. By the year 2025 it is estimated that another 17 countries will be added to that list. Some researchers believe that also be the year 2025, 35% or 2.8 billion people will face shortage. There are different reasons and causes of what continues to cause a shortage of water. Some of the water is being contaminated with pollutants. Agriculture is the biggest polluter in which the pollutants come from the fertilizers and pesticides used on the crops. The industries and municipal pollutions are also a factor. In some countries 90 to 95% of all domestic and 15% of all industrial waste goes into the water without any treatment (Knight, 1) Water shortage is also caused by the large amounts of water that is used in homes across the world. The United States uses mo ...

About Vipers, Family Viperidae

About Vipers, Family Viperidae Vipers (Viperidae) are a group of snakes known for their long fangs and venomous bite. Vipers include true vipers, bush vipers, rattlesnakes, pit vipers, adders and night adders. Venomous Fangs The fangs of vipers are long and hollow and enable the snake to inject venom into animals that it bites. Venom is produced by and stored in glands located at the back of the snakes upper jaw. When the snakes mouth is closed, the fangs recede into a thin membrane and fold against the roof of the snakes mouth. When a viper bites its victim, the bones of the jaw rotate and flex so that the mouth opens at a wide gape angle and the fangs unfold at the last moment. When the snake bites down, muscles that encase the venom glands contract, squeezing venom out through ducts in the fangs and into their prey. Types of Venom Several different types of venom are produced by the various species of vipers. Proteases consist of enzymes that break down proteins. These enzymes cause a variety of effects in bite victims including pain, swelling, bleeding, necrosis, and disruption of the clotting system. Elapid venoms contain neurotoxins. These substances disable prey by disabling muscle control and causing paralysis. Proteolytic venoms contain neurotoxins to immobilize prey as well as enzymes that break down molecules in the victims body. Head Shape Vipers have a triangular-shaped head. This shape accommodates the venom glands at the back of the jaw. Most vipers are slender to stout-bodied snakes with a short tail. Most species have eyes with elliptical pupils that can open wide or close down very narrowly. This enables the snakes to see in a wide range of light conditions. Some vipers have keeled scales- scales with a ridge in their center- while others have smooth scales. 26 Types There are currently about 26 species of vipers that are considered vulnerable, endangered or critically endangered. Some of the rarest vipers include the golden lancehead and the Mt. Bulgar viper. Like most snakes, vipers appear not to care for young after hatching. Most species of vipers give birth to live young but there are a few species that lay eggs. Vipers occur in terrestrial habitats throughout North, Central and South America as well as in Africa, Europe, and Asia. There are no vipers native to Madagascar or Australia. They prefer terrestrial and arboreal habitats. The range of vipers extends further north and further south than any other group of snakes. Vipers feed on a variety of small animal prey including small mammals and birds. Classification Vipers belong to the snake family. Snakes are among the most recently evolved of the main reptile lineages alive today. Their evolutionary history remains somewhat murky, though- their delicate skeletons do not preserve well and as a result, few fossil remains of ancient snakes have been recovered. The earliest known snake is Lapparentophis defense which is estimated to have lived about 130 million years ago, during the early Cretaceous. The viper family includes about 265 species. Vipers are classified into one of four groups: Azemiopinae: Feas viperCausinae: night addersCrotalinae: pit vipersViperinae: true vipers The Viperinae, also known as the Old World vipers, are short and stocky snakes. They have a wide, triangular head and rough, keeled scales. Their coloration is dull or cryptic providing them with good camouflage. Most members of this group give birth to live young. Pit vipers are distinct from other vipers due to a pair of heat-sensitive pits located on either side their face between the eyes and nostrils. Pit vipers include the worlds largest viper, the bushmaster, a snake native to Central and South American rainforests. The bushmaster can grow as long as 10 feet. Of all vipers, the rattlesnakes are among the most easily recognized. Rattlesnakes have a rattle-like structure at the end of their tail formed out of old layers of the terminal scale that do not fall off when the snake molts. When shaken, the rattle serves as a warning signal to other animals.

Develop arguments pro and con with respect to customized pricing. What are the differences in implementing the policy across dif - Essay Example This causes lots of competition between other stores. Many other stores will drop the product's price in order to gain revenue from it. Sometimes other stores will drop their product price so low they lose revenue. A good example would be B-to-B magazine. If the retail store calculated the revenue from other stores in the area, the retail store could come up with a lower price to attract customers. The cons of opening up two stores in two different towns may cause the retail store to lose money. Customized pricing is determined by the location in the town. Considering the two retail stores will be in two different towns they will have to go by the customized pricing terms. Many of the prices seen at one retail store may not be seen at the other retail store. Depending on what product the customer is looking for, he or she may have to drive from town to town to get the cheaper price for the product. Sooner or later it will be like the two thrift stores from different towns will be com peting. Another good example would be B-to-B magazine. If the retail store sold the magazine for a really cheap price, the store may not get a big enough revenue. The pros and cons of using customized pricing are equal. It just depends on what type of retail store that person wants to open up, or whether or not he wants to open up more than one store.

Principles of Human Resource Management Essay Example | Topics and Well Written Essays - 1500 words

Principles of Human Resource Management - Essay Example 291) On the other hand, selection can be defined as the process of determining the candidate with the best qualities for the job (Jackson & Schuler, 2000). This essay therefore seeks to critically discuss the importance of knowing the legal implications related to the key concepts explained above by the HRM. To select is to discriminate when it comes to recruitment and selection of employees. The issue in this case is not about discriminating but it is about how to discriminate fairly. In simple terms, it is concerned with how this process is done in relation to the human resources management process where job applicants must be treated fairly. In as far as the processes of recruiting and selection are concerned, it can be seen that the most important aspect is that of fairness. The employers need to be fair when they choose candidates to fill the vacant posts in their organisations. Grobler et al (2006) suggests that employers must not be influenced by factors such as race, gender, culture or physical status of a person when they select people to employ in their organisations. ... Under this law, no one is supposed to be unfairly treated as a result of gender, sex role or religion which may result in that person not getting employment even though he is qualified for that position. This law is meant to promote fair recruitment as well as labour practices where candidates for the job posts are not disadvantaged because they do not belong to a certain group of people. An organisation which does not observe this law will be committing and offence and a lawsuit can be filed against that company. It is therefore very important for the human resources management practitioners to have an understanding of the legal requirements relating to employing people. An organisation which fails to observe these legal requirements may be risking its operations given that they can have their licence cancelled and this will negatively affect the whole organisation. Companies which also fail to respect the legal requirements of employing people will risk losing money as they can be forced to pay large sums of money for violating the employment laws of the country. America is also one of the countries with clearly outlined legal requirements relating to employment of people. According to Prafdar (2001), Title VII of the Civil Rights Act of 1964 no organisation should discriminate or harass potential employees on the basis of race, religion or creed. Any company that violates these legal requirements will be committing an offence and can be prosecuted by the court of law. To avoid negative impacts on the company as a result of violating the employment laws, it is very important for the human resources practitioners to have an understanding of the legal

Is the father really a good guy Essay Example for Free

Is the father really a good guy Essay McCarthy has given a masterpiece that has moved many people with the way he constructed the story of the Road where a father and a boy were engaged in a life changing tragedy. There were also bad things that happened during that time by which one could question if the father is really a good guy. Upon reading the story, I am overly moved that the father is not that good. He may have saved the life of his son that was close to danger. The father must do it since it was his responsibility as the parent of the boy to take care of him in any circumstances until the boy reaches the right age. I think on that part, being a responsible father to him is a good sign that he gives importance to his duties and obligations as a father. The father might have provided the son with the things he need, and I think the boy greatly appreciates the effort in the story. However in the other parts of the story, the father I think was indifferent with the issues that are widespread in their place. He may have something that makes him act that way. Nonetheless, as a citizen, he must show bits of concern with her own state. Read more:Â  My Father Goes to Court Essay He must have shown concern, if not participation for the movements that might have happened in the story. Being a human being calls for many things in life. One must learn and understand that life isn’t that grand. We can’t see all the things we wanted, and never will it happen that what we expect every other people’s interactions with us be that good, the way we would treat them. Seeing the differences and uniqueness of each one of us, I guess that there really are many things that have to be considered in order to look into something if it’s really good or bad. Life on earth is not a fantasy that we can only see the good things, however seeing the other things here, the bad things, unreasonable and strange things, we must evaluate, and I guess have to do something for the situation. In the story, there were inhumanities that are witnessed and I think, being a good citizen might apply by taking into action some virtues that we learn from our ancient thinkers. Like the saying that giving is always better than receiving presents, it is applicable with the kids the father has seen. Even if they are not his sons or daughter, it was still a humane decision if he will extend a little help to them. Also, it might teach his son some of the good manners a man must do in order to give his life a better meaning. It will give the boy some ideas on how to react with every situation that comes along. If the father will just be gentle to other kids, then he (the son) might also be gentle and helpful in his future life. The end of the story was a sad one. After all his attempts to give his son a good life, the father still died and left his boy with no one else to be with. No one would have taken care of the boy not until the time he was adopted by someone with a good heart. The example that the guy has set and has portrayed in the role was the good man, who in the past has been already following them. He showed concern with the father and the son, giving the son the chance not to be miserable in that situation. Being good in the real sense is relative to the people who evaluate others. I think, in this case, I judged the father as a good father but not a good citizen. In evaluating this, he is not good since he is only good in one side. When someone or something is evaluated, it must first fit with the given categories. And since he was not consistent with the preferences I have set in seeing if a guy is a good guy or not, then he is a bad guy, ignoring some of the important things that might also affect his son in the long run. The guy could have just given his son some insights about life that will help him evaluate his own and of course, give him the idea of what a good citizen is. Instead, the other man who adopted the son was better showing concern, and seeing earlier the danger of the father overprotecting his son with all of the elements of life.

Knowledge Essay -- essays research papers

Knowledge   Ã‚  Ã‚  Ã‚  Ã‚  Knowledge can be interpreted in many different ways. Some may see knowledge as learned education. Others may see education as intelligence. None of these perspectives of knowledge are right or wrong. Every person is entitled to their own definition, source, and use of knowledge in their lives. I view knowledge as the wisdom and insight that one may acquire over time, by personal experiences and influences in life.   Ã‚  Ã‚  Ã‚  Ã‚  Most of the basic knowledge acquired by people starting at a young age is in school. As young children, we learn elementary facts such as our numbers and the alphabet. The older we become, the more facts we are taught, and the more complex these facts become. The knowledge one may learn in school is what I think of as worldly knowledge that will get people into the colleges and jobs that they may desire. The people that are abundant in educational knowledge are the people who dominate our economy and run our country. Certainly, this is one of the more important types of knowledge there are and definitely one that we could not do without, but it is not quite as important as some of the others. Education is vital in life, but mere facts cannot aid in the solution to all problems.   Ã‚  Ã‚  Ã‚  Ã‚  Another source of knowledge is entertainment, such as in television, movies, books, or even music. Certain types of entertainment can even be education. For example, television shows such as â€Å"20/20† or â€Å"DateLine† are both very informative shows, but interesting e...

Popular Music and Lyrics in the 1950’s and Today Essay

Music has been known to express ideas in human emotion; music can be a release from the hectic world. But people in the 50’s did not sit back and relax to the sound of â€Å"Feel It N*gga† by 50 cent. In fact, the type of songs that 50 cent sings is far from what people in the 50’s used to listen to. Even though some elements of music haven’t changed such as pace and sentimentality in love songs, many styles of music have evolved into more aggressive lyrics and/or very explicit and vulgar wording to fit some American cultures in the year 2006. Words like â€Å"nigger†, the involvement of sexual intercourse, and the presence of violence has manifested itself into songs today, unlike the older musical generation. One of the very little unchanged aspects of music is the pace of love songs. Love songs have two kinds of pace: fast and slow. An example of a fast paced song in the 50’s is the song by The Platters, â€Å"The Magic Touch†. This song combined the thrill of love and a fast catchy pace. This ingenious aspect is also apparent in the song by Vanessa Carlton, â€Å"A Thousand Miles†. The pace for this song is even faster than â€Å"The Magic Touch† and it is seasoned with the playing of the violin, the second fastest played instrument known to man. Another bridge between the 50’s and today is the slow pace in other love songs. In the 50’s, â€Å"Only You† by the Righteous Brothers, the pace is slow. This is evident due to the chord put in C minor which is a line of successive notes that are use as a calming remedy. In Celine Dion’s song â€Å"My Heart Will Go On†, she prolongs the final notes in order to slow the pace. The use of the flute which calms or soothes the melody of the song also aids in the slowing of the pace or tempo. Although there are some similarities the differences out-weigh them by a great deal. In the 50’s, aggression was never used in song; it would be banned by the church and labeled as songs of the devil, because of the religious innocence in that time period. It would also be banned by the government because it did not uplift the mood and morale of the veterans who had suffered mentally and physically in World War II. On the other hand, today aggression is greatly used in many examples of music, such as DMX’s previous song â€Å"Blood of my Blood†, where he uses the quote â€Å"whitey wants die why you wanna try â€Å". This quote is aggression directed at white Americans  due to the racial discrimination in the past. One of the few similarities in music from the 50’s and the music today is the sentimentality in love songs. In the song by the Righteous Brothers â€Å"Only you†, it is very sentimental; it signifies the singer’s untold love to someone. The words â€Å"Only you can make this world seem right† explain the extreme sentimental feelings for that person because of the over romanticized imagery. Today we also have very sentimental songs such as the musical number by Mariah Carey â€Å"Life Ain’t Worth Liven Without You†. Here even the title of the song is enough to show the sentimentality that is expressed in this song. Finally, one important difference is censorship. In the 50’s it was impossible to find a song with explicit language, but today, songs are crammed with provocative language and subjects that can be offensive to many people. For example, the lyrics by Ludicrous in his song the 411 † I got h*s in different area codes â€Å"or in the song â€Å"Colt 45†³ by Afroman stating† I got a box o weed and a bottle of wine I’m gonna f*ck This b*tch just one more time†. Such profane language would never have been used in the 50’s. One would notice that there are more women’s rights today than in the 50’s, yet such profanity, which may be viewed as offensive in a feminist point of view, is still sold today. In conclusion, the musical styles and rudiments of North American music have been vastly changed to reflect some aspects of U.S society today. Musical aspects such as pace and sentimentality in love songs may not have changed; however, many styles of music, in comparison to the 50’s, have evolved into more aggressive or vulgar lyrics. Simple fast tempo music can no longer elevate the mood of the majority, and the vast differences will only change even more in the years to come. In the 50’s a simple â€Å"AWAP BA DA LU BOP A WAM BAM BOOM† was the essence of music that was â€Å"hip† .Today, very large amplifiers are used to magnify the sounds of â€Å"cool† lyrics.
