Population in Mexico City free essay sample

Effects of over population in Mexico City There are parts of the world that have an alarming overpopulation rate, one of these locations is Mexico city which is located in the Federal District, Capital of the Country of Mexico. Mexico Citys enormous population continues to rapidly increase every day. With approximately 20 million residents; up from 9 million only 20 years ago, Mexico City is considered the most populous urban center on earth. There are many people in the country of Mexico who move to Mexico city because they feel that there are better life and employment pportunities there, however there are also hundreds of people that are born there every year and these factors contribute even more to its overcrowding and overpopulation. Mexico City has a poor living habitat because it is located in the Valley of Mexico, which is highly vulnerable to volcanic eruptions and earthquakes. These natural disasters have caused much destruction making these grounds to be weak and dry, nev er the less the city is rapidly diminishing water supply which adds a danger problem to the overcrowding of it’s population. We will write a custom essay sample on Population in Mexico City or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Once its water supply is gone, the only way to receive water will be to transport it from across the mountains. Not only does the city have to pipe water in, but it also has to pipe the sewage out of waste-filled areas. This would be a very expensive undertaking and could cost Mexico City a large amount of money. In addition Mexico City contains a extremely high rate of bad air pollution which is one of the most dangerous problem and health hazard presently facing the city. The air in the city is so polluted that at times the air quality exceeds 100 times the cceptable level. There are currently thousands of factories and millions of vehicles are the main causes of the air pollution in Mexico City. Mexico City has many problems at the present time, and it does not look as if it is going to get much better in the future. Important negatives caused by such over population in Mexico city is the decreased amount of space people have. The less space people have to live in, the harder it i s for them to get along. People find themselves competing for space as well as food, water and air! This makes people’s behavior more hostile in their environment. Mexico city has a high crime rate and these city civilians are stereotyped as being people with a high lack of respect for others. Since personal space is reduced, violence is more prevalent in the most highly populated areas. This behavior is probably due to aggression and anxiety brought on by a lack of personal space. Overpopulation also leads to poverty, disease and famine as people desperately compete for jobs, food and shelter. As the earths population continues to grow, it will be harder to feed people. Furthermore, Mexico as a whole country contains a majority of catholic religious believers which means that there is very little use of birth control. This causes for couples to have large number of children which only adds to the overpopulation dilemma in this city. Consequently overcrowding also adds to the rate of poverty which essentially contributes to a lack of education. Global warming seems to be linked to pollution of the air, and the seas are being polluted by oil spills and waste dumping. Fewer people would mean less pollution from cars, factories, planes and trains. Mankind has a responsibility to the planet, our own species and to other life forms to limit reproduction. Much more emphasis needs to be placed on planning family size. More education needs to be made available about the consequences of unchecked population growth. Free birth control and family counseling ought to be made available to everyone in Mexico not just Mexico city. The Mexican Government should take an active role in alleviating the population crisis. As a monetary incentive to remain childless, tax rebates should be given to people who dont have children. The population bomb threatening the earth can still be defused. If the population problem were addressed, the rest of the worlds woes would be much easier to remedy. Overpopulation underlies most problems facing many places all over the world, and one of them being greatly affected is Mexico city today. People can all help by limiting their own family size and encouraging young people to do the same and voting for laws to encourage zero population growth. A brighter future will be their reward.

Pierre Curie - Biography and Achievements

Pierre Curie - Biography and Achievements Pierre Curie was a French physicist, physical chemist, and Nobel laureate. Most people are familiar with his wifes accomplishments (Marie Curie), yet dont realize the importance of Pierres work. He pioneered scientific research in the fields of magnetism, radioactivity, piezoelectricity, and crystallography. Heres a brief biography of this famous scientist and a list of his most notable achievements. Birth: May 15, 1859 in Paris, France, son of Eugene Curie and Sophie-Claire Depouilly Curie Death: April 19, 1906 in Paris, France in a street accident. Pierre was crossing a street in the rain, slipped, and fell under a horse-drawn cart. He died instantly from a skull fracture when a wheel ran over his head. It is said Pierre tended to be absent-minded and unaware of his surroundings when he was thinking. Claim to Fame: Pierre Curie and his wife  Marie  shared half the 1903 Nobel Prize in Physics with Henri Becquerel for their research into radiation.Pierre also received the Davy Medal in 1903. He was awarded the Matteucci Medal in 1904 and the Elliot Cresson Medal in 1909 (posthumously).Pierre and Marie also discovered the elements  radium  and  polonium.He also co-discovered the piezoelectric effect with his brother Jacques. The piezoelectric effect is where compressed crystals give off an electric field. In addition, Pierre and Jacques found crystals could deform when subjected to an electrical field. They invented the Piezoelectric Quartz Electrometer to aid in their investigations.Pierre developed a scientific instrument called the Curie Scale so that he might take accurate data.For his doctoral research, Pierre examined magnetism. He formulated a description of the relationship between temperature and magnetism that became known as Curies law, which uses a constant known as the Curie constant. He found there was a critical temperature above which ferromagnetic materials lose their behavior. That transition temperature is known as the Curie point. Pierres magnetism research is considered among his greatest contributions to science. Pierre Curie was a brilliant physicist. He is considered one of the founders of the field of modern physics.Pierre proposed the Curie Dissymmetry Principle, which states that a physical effect cannot have dissymmetry separate from its cause.The element curium, atomic number 96, is named in honor of Pierre and Marie Curie.Pierre and his student were the first to discover nuclear energy from heat emitted by radium. He observed radioactive particles might carry a positive, negative, or neutral charge. More Facts About Pierre Curie Pierres father, a doctor, provided his early education. Pierre earned a math degree at age 16 and had completed the requirements for a higher degree by age 18. He could not immediately afford to pursue his doctorate, so he worked as a lab instructor.Pierres friend, physicist Jozef Wierusz-Kowalski, introduced him to Marie Sklodowska. Marie became Pierres lab assistant and student. The first time Pierre proposed to Marie, she refused him, eventually agreeing to marry him on July 26, 1895.Pierre and Marie were the first to use the word radioactivity. A unit used to measure radioactivity, the Curie, is named in honor of either Marie or Pierre or both of them (a point of argument among historians).Pierre was interested in the paranormal, as he believed it might help him understand physics better and especially magnetism. He read books on spiritualism and attended seances, viewing them as scientific experiments. He took careful notes and measurements, concluding some phenomena he witnesse d did not appear to be faked and could not be explained. Pierre and Maries daughter Irene and son-in-law Frederic Joliot-Curie were physicists who studied radioactivity and also received Nobel prizes. The other daughter, Eve, was the only member of the family who was not a physicist. Eve wrote a biography about her mother, Marie. Pierre and Maries granddaughter Helene is a nuclear physics professor and grandson Pierre is a biochemist. Their parents were Irene and Frederic Joliot-Curie.  Pierre Joliot is named for Pierre Curie.

Importance of Iron to the Evolution of Civilization in Africa Essay

Importance of Iron to the Evolution of Civilization in Africa - Essay Example While paying attention to the Iron Age in Africa, this expose elucidates the important role of iron to the evolution of civilization in the continent of Africa. African used stones as tools to conduct their daily activities during the first Millennium (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). In this regard, the activities that they engaged in included hunting and gathering, which was the main source of livelihood for a majority of Africans. Therefore, there were no signs of metalwork in Africa in this millennium. However, the continent traces early signs of metalwork in Egypt during the fifth millennium (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). In this regard, the first metalwork witnessed in the continent was technology in copper work. Indeed, this innovation coincided with farming and agriculture in the Nile Valley, which is the earliest civilization in Africa (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). While copper was the first metal for Africans to work with, there are several standpoints regarding the origin of iron in Africa. Nevertheless, there is a common agreement that the first evidence for work related to iron was in the second millennium (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). According to archeological standpoints, iron traces its origin on two different perspectives. In the first perspective, archeologists identify the invention of iron by the indigenous Africans as the group that invented iron (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). Archeologists who support this position indicate that Africans invented iron smelting by borrowing from the techniques they used in copper smelting (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). On the other hand, a second group of archeologists traces the origin of iron in Africa from the surrounding continents and specifically the continent of Asia (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). In this regard, the archeologists who support this viewpoint indicate that smelting of iron diffused into the continent through Egypt. It is crucial to point out that Egypt is close to the countries in the Arabic area of the continent of Asia. In this case, Egypt received the technology and spread it to the rest of Africa. The interaction of the kingdom of Meroe with the Egyptians is a contributing factor in the spread of iron technology and its crucial role in the evolution of civilization. In this regard, the principal craft for the people of Meroe was using the iron technology to make iron tools (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). The tools previously used by the people of Meroe were not of superior quality, since the only technology before the use of iron was use of stones or copper. In this regard, iron provided the people of Meroe who engaged in farming and hunting with more superior tools (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). In effe ct, the new tools ensured that there was more production of food and hunting became more productive. In addition, these superior tools paved way for a stronger army amongst the Meroe since they now had superior tools. In addition, they could capture strong animals like the elephants, which they used during wars (â€Å"Early Iron Age in Sub Saharan Africa,† n.d.). Thus, iron was important to the evolution of civilization in Africa since there were inventions of superior tools used in farming and

Gun control Research Paper Example | Topics and Well Written Essays - 1500 words - 5

Gun control - Research Paper Example Many cases of gun related crimes and fatalities have been reported within the country which indicates that public access to guns may be more harmful that beneficial. In this way, the society should understand the important of gun control laws and limiting access to citizens that access guns while addressing arguments opposing them as a way of saving lives. Gun violence is a common phenomenon in the American society and the National Victimization Survey showed that 467, 321 people died in 2011 as a result of criminal activities using firearms. The FBI generated a report in 2011 that testified that 68% of homicides and 41% of violent robberies as well as 21% of aggravated attacks are done using guns. In addition, hand guns are the most common firearms that are used in criminal activities especially homicides committed each year. This research shows that gun violent is a reality within the society and many people use them to intimidate victims. It is also clear that most hand guns are involved in criminal activities like assault, in various threats that are done without injury, and in many cases of rape or robbery (Zimring 723). Gun ownership is another apparent issue in the United States with findings showing that more than 200 million firearms were in private ownership in the 1990s. Through the years guns among private ownership have increased especially due to creation of new households and more wealthy people who needed to acquire firearms. In other areas, the increasing crime rates within the country motivated citizens who initially did not have guns to acquire them in a bid to seek protection. It is evident however that the reason that people own guns is more related to crime rates compared to having more wealth. Nonetheless, it is also evident that many firearms, specifically the long guns are acquired for recreational activities like hunting which is not related to

Diary Entry of John Proctor Essay Example for Free

Diary Entry of John Proctor Essay Tomorrow is the day of my execution. For once of my life I lied, I confessed to something I do not believe, I betrayed my friend. I am a man of sin, I told Danforth that they were all involved in witchcraft, I thought I would not feel guilty about it since they are already dead and I am doing this for my family. My beloved wife Elizabeth needs a man in the household, and my children, they need a father. I thought putting my family as my first priority, even more important than honor and the truth; but I am wrong, seriously wrong. I used them, my neighbors, my friends in order to persuit my own happiness. I used them, I am a man of sin. I am now a man of sin, and this is all because of that lustful woman named Abigail Williams. I admit that I did like her at first, her beauty deeply attracted me and I did something that was a shame for my whole life, I betrayed my wife Elizabeth. I dont know what I was thinking back than, but I certainly regret it now. Elizabeth trusted me, our family were united, everything were fabulous until that woman came into my life. If there were anyone that is actually the devil, is must be her, Abagail Williams. She didnt just ruin the life of my household, but everyone in Salem, the Coreys, the Nurses, even the Putnams were ruined because of that devil and her so called witchcraft. Because of her, nobody in Salem could live the lives they had, everyone went crazy, everybody is accusing each other in order to keep themselves away from harm. Maybe Abagail didnt realise that the results will turn out to be like this, but this is reality. Its all because of her lust, her thirst for power, her wicked sick mind, its all because of her. It is Abagail that drove everyone mad. It is Abagail that made everyone suspiciouse of their neighbors and friends. It is Abagail that killed out people in Salem. And it is Abagail that made me have to lose my word, it is her that made me confess to a lie. It is Abagail Williams who turned me into the man that doesnt worth anymore credit, it is Abagail that killed me. Abagail Williams is not saint that confessed to the truth, but a murderer that slaughtered the nice people of Salem. Tomorrow is my last day living, how will the people of Salem view me? Maybe they will take me as the villian that blackened the saints names, or maybe they will see me as a man with honor, to die like a man not a coward that wouldve done anything to save my own life. I will die like a man.

What Is The Bible? Essay -- Religion Bible

The Bible is the most significant book in the history of civilization. In the context of Jewish history, the Bible’s impact on politics, history, and religion is without comparison. Along with establishing the covenant-based legitimacy of the Jewish people and their history, the Bible’s political impact is exemplified through prophetic politics, the power of kings, and the effects of political authority. Biblical archeology has discovered biblical structures which supports the historical validity of the Bible. The Bible’s effect on history, politics, and religion has shaped the world we live in today. In order to comprehend the level of significance the Bible represents, one must systematically break down the structure of the Bible. Religious writings of both Judaism and Christianity compose the Bible and are dependant on the religious traditions of a specific denomination. In the context of Judaism, Tanakh is the Hebrew name of the Bible composed by the three parts of the Hebrew Bible: the Torah, Nevi’im, and Ketuvim. The Torah includes the â€Å"Five Books† of Moses which establishes God’s covenant with the Jews. The Nevi’im discusses the division of the two kingdoms, Israel and Judah, and acknowledges different prophets. The Ketuvim is composed of poetry, writings, and the stories of Jewish prophets. The books written after the Hebrew Bible, referred to as The New Testament by Christians, contain the accounts of Jesus and his disciples. The New Testament plays a central role in Christianity just as the Hebrew Bible, or commonly referred to as the Old Testament, provides the foundation for Judaism. The first book of the Bible, Genesis, sets the framework in which Judaism is rooted. Genesis is vital to the religio... ...ness of the Jewish People in accordance to their covenant with God. The Bible also legitimizes the Holy Land belonging to the Children of Israel while establishing Judaism as a Mosaic religion. The Bible provides the basis for Halakha, a corner stone in Judaism. Along with the Old Testament, the Bible plays a prominent role in the development of Christianity. The Gospels of the New Testament assert Christian ideologies and values which clearly be seen influencing the Western world today. Not only did the Bible affirm Judaism and Christianity, it gave a glimpse into the earliest form of politics in the ancient world. Archeology has advantageously legitimized the historical accuracy of the Bible by producing evidence that coincides with the Bible’s narratives. The Bible will continue to play an important role in society as it will continue to shape civilization.

Justice look

When you look up synonyms for the word Justice, or ask someone what they think the word meaner, they will spew out nouns such as: neutrality, fairness, impartiality's, etc. I believe Justice in terms of the criminal system is the collaboration of three different entities, police, court, and corrections. That have to work together to form an illusion of one single entity; and in doing this, they have to still maintain a check and balance system amongst themselves. So, no one system should be able to have full authority.For only by this can it strive for the ability to bring about a system that can observe eternally, Judge fairly, and the ability to weigh each investigation and case with a sense of impartiality. The main components of the criminal system are the police, court, and correction unit. They have to interact with one another by a collective meaner. You have the law enforcement in the forefront; they are the ones that have to enter the â€Å"crime scene,† take into con sideration all the evidence, collects the evidence, and they have to arrest the suspect.Once they have apprehended the suspect perceived to be the doer of the crime. The suspect at this time is taken to the rout; the evidence collected by the police is then presented at the court. Case is made by both prosecution and defense team. You have the unbiased Jury and Judge that view the case, evidence, and testimony; they deliberate and come back with a sentence. Once the suspect is sentenced, if found guilty, they are sent to a correctional institute. The correctional unit officers have to supervise the convicted felons.They have to ensure that their facility is well situated and capable of holding the convicted felons, so that both the inmates and the public can co-exist in a safe environment. The two models of the criminal Justice system are: The crime control model and the due process model. The two models differ from each other through which part of the Justice system they put their emphasis on. The Crime control model put their importance on reducing crime and criminal activities in society through implication of the Law enforcement officers, I. E. Alice/detective, taking control and in theory get to the solution and conviction as soon as possible. The Crime control model Judges the person for what they did, their role in the crime. It is more cut and dry. They believe the severity of the punishment should correlate with the crime. This theory allows for capital punishment, they don't believe one can change, or give too much importance for mental status, ethnicity, age, race, etc. The Due process model is quite the contrary, it stress the importance of taking into consideration ones race, age, demographics, etc.The Due process model put importance on respecting ones rights and following all the responsibilities of the law. While still protecting ones freedom. I think the fact that the main components of the Justice system sometimes inflict with each other are the reason why some cases get thrown out. A case, that I remember, is the clear epitome of when the Justice system failed; it took place in the 1993 â€Å"West Memphis Murders. † Three boys were killed in a horrific manner. Why were the murders not solved?Lack of poor evidence collected, rash decisions making, jumping to conclusion, media hype, and the police not following up on hints that were called in. They arrested three boys because they portrayed eccentric behaviors. They went on hearsay; they let the pressure of the media and public convict three caked proper detective tactics, and they pressured one of the suspects into admitting guilt. The Jury wasn't unbiased, everyone felt these boys were guilty and thus found them guilty.Had the law enforcement officers done their Jobs properly they would have followed up on the clue where there was a man completely bloody and delusional, in the bathroom of a fast food restaurant. The cops never showed up there to talk to him, the y went the next day to the restaurant took samples a sample of DNA, blood smear from the wall, and they lost that only sample of evidence. That case went unsolved, a case of three eight or nine year old boys. That shouldn't have happened. The system will fail if the three different entities of the Justice system don't act as one.Technically, I believe the crime control model is more useful because you get a verdict, action is taken, a suspect guilty of a crime pays for that crime accordingly to the severity of the crime; without technicality changing the sentence, or race, demographics, age playing a rule in how severe or lack of severity of the punishment. More criminal activities would be accounted for; people would fear law enforcement officers more. The due process model is more efficient and accurate. They enforce the rules and regulations of the law; they make sure any suspect is treated with the respect they deserve in accordance with the law.I believe both systems need to in teract with one another for it to be fair and Just. One system may come to a conclusion too quickly, while the other may allow someone guilty to get out of crime do solely to a technicality, so no one system is perfect on its own. However, I do believe the crime control model should be more prevalent in the Justice system. I think too much consideration is given to suspects, and why call someone suspect when their guilt is so evident, that really it's a point one percent chance for them not to have committed the crime.I think the severity of the crime should matter; a pedophilia serial killer should not be turned to life in prison where our tax money pays for their living. I don't think capital punishment should be banned; there are some out there that honestly don't deserve the â€Å"luxury' of a prison. An example of this would be, the Jodi Arias case, she stabbed her ex-boyfriend twenty-nine times, shot him, slit his throat, and left him to rot. Is it fair to say that it was an act of assign, when she stole the gun, made sure she had enough gas so that she didn't have to stop anywhere, and took pictures.
