What´s Ocean Acidification - 1292 Words

Introduction The oceans of the earth are a massive part of the natural cycles that make this planet habitable. They regulate global temperatures, absorb carbon dioxide, provide a home for millions of plants and animals that make up various levels of the food chain, and so much more. They are a resource given for us to use and benefit from, however, it is also a resource that needs to be protected. It is the fountain of life for the planet and drastic changes to the makeup of the oceans could be detrimental to life as we know it. Ocean acidification is a problem which has come to light in the last decade, but is becoming increasingly concerning to many scientists (1). In this essay I will attempt to direct your attention to some of the†¦show more content†¦In this case the CO2 is absorbed from the atmosphere into the warm surface waters and gets mixed in with the deep ocean currents and is stored. This process can be further aggravated by this excess of dead organic material providing ide al environments for anaerobic bacteria deep in the ocean which break down the material and produce CO2 as a byproduct. (3) This is a vicious cycle that becomes very hard to break The second possible cause relates to waste water from agricultural industry which is rich in nutrients but ends up being dumped into lakes and rivers. This nutrient rich water runs down to the ocean where it ends up and stimulates growth of various types of algae. These algae produce CO2 as a product and therefore raise levels of CO2 in that area of the ocean. This causes other organic material to die off and continues with the vicious cycle described above. (6) What can be done about it? Scientists are working hard to simulate conditions projected for the end of the century and beyond to determine how the ocean will be able to adapt. Natural occurrences of hypoxic zones can be used to study this and researchers have shown that although fish do live in these areas, they are not able to reproduce here but must go to areas of higher oxygen content to reproduce. (3) Concerning evidence also shows that animals with shells will not be able to survive which has serious implications for the food chain.

This sharp increase in atmospheric CO2 has had an impact on the ocean, and can be seen by the increase in the levels of gaseous CO2 in the seawater. When the CO2 rich atmosphere comes in contact with the surface of the ocean, CO2 is readily absorbed which causes the pH of seawater to become more acidic. Many enzymes and processes that occur in the ocean, like test building, are pH sensitive (Calderia, 2003).

The London Plague Of 1348 And 1665 - 1692 Words

The London Plagues of 1348 and 1665 The London Plagues refers to two periods of disease outbreak in England. One plague, the Black Death, began in 1348. Another plague, the Great Plague, began in 1665. Both of these outbreaks killed a substantial amount of the population at the time. The plague exists in two forms: bubonic and pneumonic. A bubonic plague is spread by flea bites and results in painful sores on the body. A pneumonic form of the plague is airborne and spread by coughing and sneezing. Both the Black Death and the Great Plague existed in both forms of plague that resulted in widespread death and affected permanent change in English society in different ways. The Black Death An outbreak that occurred in 1348 and lasted until 1350 and popped up a few more times in later years in England is known as the Black Death. This deadly plague occurred in Medieval England, so there was not enough medical knowledge to help combat its spread. The outbreak became an epidemic, killing six out of every 10 people in London, or 1.5 million of the four million people who were living there at the time (Appleby 162). How It Spread Asia is the likely origin of the Black Death, which was long believed to have only been the result of the bites from fleas that had also bitten infected rats (Appleby 163). It was thought that the fleas injected the disease into the victim during the bite (Appleby 163), but recent medical evidence proves this was only one way the disease wasShow MoreRelatedThe plagues in England Essay1044 Words   |  5 PagesIn England there were three specific plagues that i will be talking about, they are the bubonic plague â€Å"The Black Death†, pulmonary plague and the pneumonic plague.

atomic bombing Essay Example For Students

atomic bombing Essay Nuclear war was brought about through the invention of the atomic bomb. The atomic bomb was first thought of in 1939. The Manhattan Project was devoted to researching and constructing the bomb (Serendipity: Manhattan Project para.1). Six years and 2 billion dollars later the Manhattan Project produced the first atomic bomb in history (Serendipity: Manhattan Project para.5). The bomb was tested in northern New Mexico on July 16th, 1945. The creators of the bomb watched the first detonation. One creator quoted from the Bhavad Gita saying, I am become death, the destroyer of worlds. The testing of the bomb in New Mexico was the first detonation, however it was not the last (Serendipity: Manhattan Project para. 10). The atomic bomb was again set off in Hiroshima on August 4th, 1945. This time the bomb was used in warfare (Serendipity: Detonation para.1). Two aspects of these bombings were the injuries to the people caused by the bomb and the long-term effect the bombing had on the culture.There were three main kinds of injuries caused by the bombing: burns, mechanical, and radiation. The burns were due to the flash radiation of heat. The mechanical injuries were caused by debris in the air thrown by falling buildings, etc. the radiation injuries were from the gamma rays produced from the nuclear bomb itself (Avalon: Characteristics of Injuries para.1). Without exact numbers it is hard for experts to determine the actual death rate caused by each injury. Most would say that that majority of the deaths were caused by either radiation or mechanical injuries (Avalon: Characteristics of Injuries para. 2). Two different kinds of burn were reported after the bomb, flame burn and flash burn (Avalon: Burns para.1). People that had any sort of protection or shielding around them were protected from flash burns (Avalon: Burns para. 4). Japanese experts estimate that burns caused at least 50 percent of the deaths in Hiroshima. They say that most burn victims died instantly (Avalon: Burns para.5). The second form of injury due to the bomb was referred to as mechanical injuries. These injuries were cause by flying objects, falling buildings, crumbling walls, etc. People that were injured from these things experienced fractures, lacerations, concussions, abrasions, etc (Avalon: Burns para.1). The third and most talked about injury caused by the bombing were the radiation affects on the human body. Most people were expected to experience the affect of radiation seconds after the bombing. However, some people did not start having symptoms until 3 weeks after the bombing (Lifton pg.35). The symptoms start out with the person feeling nauseated, weak, and light headed. They continue with vomiting and diarrhea. Eventually the persons hair will fall out and their white blood count will drop (Lifton pg.35). That person will then gradually weaken until they meet their death. Not all people that were injured from burns, mechanical, or radiation injuries died. The people that survived next dealt with an entourage of rumors and questions. Rumors went around about flowers and trees never growing on the land again. People claimed that no one would be able to live in Hiroshima for at least seventy-five years (Lifton pg.36). Well, the flowers grew again along with the trees and people were able to live in Hiroshima after the bombing. But would the culture ever be the same? Would people in Hiroshima ever be able to move on with their lives? If so, how? Today the culture in Hiroshima is as strong as it ever was. Some may even say it is stronger or closer due to the unity the bomb brought about in the city. People do not shut the bombing out by forgetting about it or not talking about it. They tell their children about it, teach it in school, and every August 6th they gather together in a park and remember together (WWW Museum para.1). .uae71718e064983c1c4d02a716cb981cd , .uae71718e064983c1c4d02a716cb981cd .postImageUrl , .uae71718e064983c1c4d02a716cb981cd .centered-text-area { min-height: 80px; position: relative; } .uae71718e064983c1c4d02a716cb981cd , .uae71718e064983c1c4d02a716cb981cd:hover , .uae71718e064983c1c4d02a716cb981cd:visited , .uae71718e064983c1c4d02a716cb981cd:active { border:0!important; } .uae71718e064983c1c4d02a716cb981cd .clearfix:after { content: ""; display: table; clear: both; } .uae71718e064983c1c4d02a716cb981cd { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uae71718e064983c1c4d02a716cb981cd:active , .uae71718e064983c1c4d02a716cb981cd:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uae71718e064983c1c4d02a716cb981cd .centered-text-area { width: 100%; position: relative ; } .uae71718e064983c1c4d02a716cb981cd .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uae71718e064983c1c4d02a716cb981cd .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uae71718e064983c1c4d02a716cb981cd .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uae71718e064983c1c4d02a716cb981cd:hover .ctaButton { background-color: #34495E!important; } .uae71718e064983c1c4d02a716cb981cd .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uae71718e064983c1c4d02a716cb981cd .uae71718e064983c1c4d02a716cb981cd-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uae71718e064983c1c4d02a716cb981cd:after { content: ""; display: block; clear: both; } READ: Invisible Man - Identity Essay Hiroshima today is officially named the city of peace(Lifton pg.38). The target for the bombing in Hiroshima was the Aioi Bridge. Today the Ota River, which runs under the bridge, brings back memories for those that lived through the bomb. When most people walk by the water they see a clear stream of water, however when survivors walk by they remember the river as a place of dark water filled with blood and bodies (Lifton pg.37). Near the river is a large building that is dome-shaped. Before the bombing this building was The Industrial Exhibition Hall. This building now serves as one of the few surviving buildings from the bomb. Most of the building is in ruins and has been gutted out due to the nuclear explosion. After the war many Hiroshima citizens felt the building should be torn down. They felt if it was torn down people could forget and move on with their lives. However, others had different views. Some thought the building should stay up to warn the rest of the world and show the destruction the bomb caused. And still others felt the building should just remain until it falls down naturally on its own. Finally, the government decided to preserve the building in its natural setting. The building is now referred to as the Atomic Dome(Lifton pg.38). The Ota River along with the Atomic Dome are located in the peace park in Hiroshima. The peace park is also home to the Cenotaph. This building was built to model an ancient clay house. It was made for people to remember those that died in the bombing. Names are listed on the building and as survivors pass away their names are added to the structure. People believe that this is the place that the souls of those that perished in the bomb are buried. With that in mind they come here bringing flowers, cards, candles, and other things to show their respect. Above the names there is a statement saying, Rest in peace. The mistake will not be repeated (Lifton pg. 42). For those that could not be recognized, or found after the bombing there is a separate memorial. This is referred to as the Memorial Mound. Tens of thousands of boxes of ashes were place in this mound of burned bodies that could not be identified. Still today remains are found in excavation sites and are cremated and stored with the others. There in that tomb they wait to be claimed by friends or families(Lifton pg.45). Another place for people to mourn is the Childrens Monument. The monument was built in 1958 in memory of Sadako Sasaki. She is said to be the Anne Frank of Hiroshima. Sadako died ten years after the bomb due to delayed radiation effects on her body. The monument is not only to honor Sadako but also the many children that died in the bombing. On the top of the monument there is a young statue girl that stands holding a crane in her arms. Inside the monument is room to store the many cranes that children all over the world have made and sent to Japan. Inscribed on the base are the words, This is our cry, this is our prayer: Peace in the world!(Lifton pgs.47-49). Another place to remember or learn about the bomb is the Peace Museum. The museum displays peaces of glass and other materials, showing how the bomb affected each thing. The director of the museum says its purpose is to educate the millions that view it each year, not to shock them(Lifton pgs.50-61). With all of the monuments, museums, and memorials in Hiroshima it is hard for the people to forget about the bombing. .u5e27512977fb34c883e6e48e4f5082cb , .u5e27512977fb34c883e6e48e4f5082cb .postImageUrl , .u5e27512977fb34c883e6e48e4f5082cb .centered-text-area { min-height: 80px; position: relative; } .u5e27512977fb34c883e6e48e4f5082cb , .u5e27512977fb34c883e6e48e4f5082cb:hover , .u5e27512977fb34c883e6e48e4f5082cb:visited , .u5e27512977fb34c883e6e48e4f5082cb:active { border:0!important; } .u5e27512977fb34c883e6e48e4f5082cb .clearfix:after { content: ""; display: table; clear: both; } .u5e27512977fb34c883e6e48e4f5082cb { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u5e27512977fb34c883e6e48e4f5082cb:active , .u5e27512977fb34c883e6e48e4f5082cb:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u5e27512977fb34c883e6e48e4f5082cb .centered-text-area { width: 100%; position: relative ; } .u5e27512977fb34c883e6e48e4f5082cb .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u5e27512977fb34c883e6e48e4f5082cb .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u5e27512977fb34c883e6e48e4f5082cb .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u5e27512977fb34c883e6e48e4f5082cb:hover .ctaButton { background-color: #34495E!important; } .u5e27512977fb34c883e6e48e4f5082cb .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u5e27512977fb34c883e6e48e4f5082cb .u5e27512977fb34c883e6e48e4f5082cb-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u5e27512977fb34c883e6e48e4f5082cb:after { content: ""; display: block; clear: both; } READ: Henry Carey Essay What happened that August 6th will be remembered with the citizens of Hiroshima for years to come. The bomb in Hiroshima will be remembered forever. It will be passed down through history books and memorials. The disease caused by the bomb will exist in peoples minds instead of their bodies. The culture will forever be affected by the bombing. Lifton gives this advice in going to view the city, To begin with this place youve come to see called Hiroshima is no one place. There are many places, each bearing that name. One is located in the past. One in the present. One in the future. Understand, the legendary place that you seek is not located on a map. It is a state of mind. (Lifton pg.7).
