...clone animals that have gone extinct. Jurassic Park is a movie series based on what happens when a scientist did manage to clone these extinct creatures. The DNA of a woolly mammoth has recently been found, and now the discussion of cloning has been back in the media. This has become an important topic that society needs to think about now that technology has continued to advance. Bringing back extinct creatures could become a reality, not just science fiction. Animals that have gone extinct need to stay that way, scientists need to stop focusing our time and money trying to bring them back. It is costing too much money, ignoring other major problems, and not taking into account the diseases these creatures...

...De-extinction is the process of bringing bringing back animals.It sounds like a scientific term to bring animals back like the wooly mammoths.We need to bring them back because they are like elephants and a lot of people never have seen them in real life except for cavemen.I think that this is a very good idea. First we need to research to find the evidence that mammoths are very important and that we need to bring them back.George Church says de-extinction is a good idea.”Mammoths could keep the region colder by eating dead grass thus engaging the sum to reach spring grass whose deep roots prevents erosion” (Church,G.,2013).This is telling us that in the hot summer the mammoths could eat some dead grass and then they would cool us down a little bit for us people and them.This will help the temperature.”Scientist could bring mammoths back to life by targeting and replacing the specific genomic sequences in a closely related living species” (Draxler,B., 2013).They would be able to bring them back for people to see and to replace them with other animals that are about to go extinct....

... There are 16,928 species listed as endangered and 905 listed as extinct in the International Union for Conservation of Nature’s Red List criteria (Tobin, 2010). Many ways have been discussed on how to prevent these endangered species from adding to that list of 905, but most have failed. The most basic and probably most efficient way to end extinction of species would be to stop invading their habitats. However, that won’t happen. So, scientists have dug deeper into biology and are testing stem cells on these endangered animals in an effort to put them back at a sustainable level of species survival. This stem cell research is a very good strategy to help these endangered species and prevent their extinction. Stem cells are biological cells found in multicellular organisms that can divide into many different specialized types of cells. The potential for these cells to divide into specialized cells is called potency. Stem cells can self produce, which makes them very useful in the medical field. The two categories of stem cells are embryonic and somatic. The embryonic stem cells are obtained from embryos form using in vitro fertilization. Somatic, or adult, stem cells are obtained from bone marrow, the heart, brain, and other parts of the adult body, but are very small in quantity, which makes them more difficult to obtain (‘Stem Cell Information”, 2009). Some say that stem cell research should not be carried out because of what their religion tells them. In my...

...In the story “ Genetic Engineering”, by Louise I. Gerdes, it is about scientist trying to find out how DNA can be cloned and how their genetics can be copied to find out what could happen. There are a lot of risks and benefits in this process but they influence people towards genetic engineering. In the experiment of genetic engineering it can help care kids from disease before they are born and will help cure many illnesses that the body may contain. Many of the medicines and food that have been made was created by the genetic engineering which have benefited millions of people today in life. There are a lot of disadvantages and advantages of genetic engineering and there are a lot of people that lose their life through the 2 process of cloning...

...Hannah Jones AP English P. 2 Research Paper 3/8/13 Illegal Ivory Trade Extinction rates have jumped massively in the last few years from one to two species going extinct per year to currently up to ten disappearing off of the face of the Earth per year. This problem seems to be getting worse and worse every year. In Africa, the elephants are disappearing rapidly. With such a fast rate, scientists believe all elephants will be extinct by the year 2035. In the 1980s, there were over a million elephants in the population; today there are less than 470,000. Illegal poaching seems to be the greatest cause of the loss of these animals because of the value that their ivory tusks have in the market. Are we just going to let all of the African elephants die for the selfish wants and need for an immaterial item of other people? Poaching is the illegal hunting, killing, or capturing of wild animals. Examples of poaching include hunting without a license or permit, use of a prohibited weapon or trap, hunting at the wrong time of the year, and hunting in a sanctuary or reserve, national park, or zoo. Poachers usually only take a very small part of the killed animals letting the rest of the animal carcass to rot and waste away. The ivory trade is highest today in Africa, China, and Japan with the U.S. Following right after. The demand for ivory is still on the rise. Ivory sculptures are common in the Asian culture, as well as ivory handles for guns and knives. Jewelry and piano...

...I support the initiative to reintroduce the gray wolf back into Yellowstone Park. I support bringing them back to our national park because they are amazing animals that we can research and learn more about. They are also endangered and must be protected. We also can use the presence of wolves as a way to attract more visitors to our national parks. Based on these reasons, we should work to support this cause as soon as possible to save the wolves and bring them back to our parks. Wolves are unique animals in their ability to communicate with their pack mates, hunt for prey, and work in groups to survive. Wolves are legendary because of their spine-tingling howl, which they use to communicate. A lone wolf howls to attract the attention of his pack, while communal howls may send territorial messages from one pack to another. Some howls are confrontational. Much like barking domestic dogs, wolves may simply...

...just a few weeks old baby seals, the seals scream, shake, and try to get off the ice floes. The seals that are successful getting off the ice floes but are already shot will slip beneath the water’s surface where they will slowly die from their wounds. Then, once the vessel reaches the ice floes the sealers run to the shot and wounded seals with their hakapiks, which are large wooden clubs with a curved ice pick at the end to drag the seals across the ice. When the sealers reach the wounded screaming baby seal, they then club it over the head. Hopefully, but rarely does it this happen, the seal will be dead. Finally, the sealer jabs the hakapik pick into the seal’s back to the vessel, where it will be skinned, all the while the seal is shaking and moaning still. This is not an acceptable way to be hunting animals in today’s society. Canada’s Department of Fisheries and Oceans (DFO) is not big enough to regulate the commercial hunt, and there is too much waste in the seal hunt. The apathy of hunters towards the barbaric manner in which the seals are treated extends to those within the Canadian government. John Efford, former Canadian Minister of Natural Resources (“Why”) is quoted as saying: “Mr. Speaker, I would like to see the 6 million seals, or whatever number is out there, killed and sold, or destroyed and burned, I do not care what happens to them…the more kill the better I will love it.” The...

...What is Cloning? Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical. Clones can happen naturally—identical twins are just one of many examples. Or they can be made in the lab. Below, find out how natural identical twins are similar to and different from clones made through modern cloning technologies. How Is Cloning Done? Many people first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Artificial cloning technologies have been around for much longer than Dolly, though. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer. 1. Artificial Embryo Twinning Artificial embryo twinning is a relatively low-tech way to make clones. As the name suggests, this technique mimics the natural process that creates identical twins. In nature, twins form very early in development when the embryo splits in two. Twinning happens in the first days after egg and sperm join, while the embryo is made of just a small number of unspecialized cells. Each half of the embryo continues dividing on its own, ultimately developing into separate, complete individuals. Since they developed from the same fertilized egg, the resulting individuals are genetically identical. Artificial embryo twinning uses the same approach, but it is carried out in a Petri dish instead of inside the mother. A very early embryo is separated into individual cells, which are allowed...

...control the earth and do with as they please they can an in many cases unintentionally destroy the earth and its natural resources. One environmental issue caused by human impact is the overfishing of the Bluefin Tuna to the point where it has been placed on the critically endangered species list. Bluefin Tuna are being overfished at an alarming rate this human greed from a Buddhist perspective will cause the depletion and over all extinction if nothing is changed. Bluefin Tuna populations in the Atlantic Ocean have declined over 70 percent in the last thirty years yet because seafood is a global commodity being flown into markets around the world the demand has become unquenchable. Overfishing for Bluefin continues scientist expect the fish to become extinct by 2012 if nothing changes. (PBS.org) The Bluefin Tuna is a species of Tuna native to both the western and eastern Atlantic Ocean as well as the Mediterranean Sea. This is a relatively large species of fish. A full grown male can average six to eight feet long and can weigh up to 770 pounds, although the Bluefin is capable of reaching over one thousand pounds. Bluefin Tuna are robust and rhomboidal in shape. They have dark blue upper body and grey below with a gold glint covering the body. They also have bright yellow caudal fins. Bluefin can live up to 30 years but due to heavy fishing mortality few specimens grow to a mature age.("Northern Bluefin Tuna") Bluefin are carnivores in nature they typically hunt small...

...Madagascar Rainforest Madagascar, located approximately 400 kilometers east of Africa is the world's fourth largest island. Because of its isolation it is occupied by some of the most unusual and rare species of plants and animals on earth. Madagascar was at one time formerly an independent kingdom; became a French colony in 1896 and regained independence in 1960. During 1992-93, free presidential and National Assembly elections were held ending 17 years of single-party rule(Science 1990). The main historical problem with international trade has been the correlated destruction of the environment. This is especially true when it comes to the issue of deforestation. In Madagascar, (Economic Geography, 1993) people have been cutting down the forests for decades. Throughout the past century, much of the rainforests of Madagascar have disappeared. People have begun moving out of the cities, industries have started to expand, and the use of land for farming (particularly coffee) has dramatically increased. All of these phenomenons have led to the destruction of the forest of Madagascar. Many plants and animal species have been severely endangered due to the deforestation (New Scientist 1990). With a current population near 14 million and growing at roughly 3% yearly combined with a per capita income of $230 per year, the major threats to the remaining forest are driven by subsistence needs and cutting for fuel. This has become a major issue, not only because of the value...

...The standardization of spelling is mainly due to dictionaries, that determine how a word should be spelled, pronounced and defined based on its usage, moreover, dictionaries must take the changes and differences into account. Writing speech differ form the oral speech, as it has the possibility to insert punctuation, however, nowadays, writing in order to reflect the oral patterns can be accepted under certain circumstances. Those circumstances are mostly related to the Internet and the netspeak (Crystal, 2001), in which the written type look more spoken than any other type. Netspeak is often criticized as a threat to the literacy of children, but it’s still spreading and has its own features ; tolerance for typos and misspelling, optional capitalization, use of abbreviations, use of emoticons, allegro speech. Printing words had an impact on people’s language acquisition, once people realize how a word is spelled, they automatically change its pronunciation from the former, incorrect one to the correct one, that is why pediatrician encourage literacy and exposure to books the earliest for...

...Hannah Hewes February 27, 2014 Professor Helmke Business Public Policy Endangered Species Act Extinctions have occurred throughout our planet's natural history. Some species develop as others die out, making space in the ecosystem for those best suited to any given habitat's natural conditions. Long before human beings arrived, fossil records show that populations of animals evolved, thrived, declined, and became extinct. However, the rate of extinctions in the late twentieth and early twenty-first centuries drastically increased to an estimated 100 to 1,000 times the normal expected rate of extinction. The majority of these accelerated extinctions can be directly traced to mankind's impact upon the natural environment in the form of hunting, fishing, agriculture, development, pollution, habitat encroachment, disease, and global climate change. Due to the increasing number of endangered species, as well as, species becoming extinct, the United States Congress decided to take action. Congress passed the Endangered Species Preservation Act in 1966, providing a means for listing native animal species as endangered and giving them limited protection. The Departments of Interior, Agriculture, and Defense were to seek to protect listed species, and, insofar as consistent with their primary purposes, preserve the habitats of such species. The Act also authorized the Service to acquire land as habitat for endangered species. In 1969, Congress amended the Act to provide additional...

...Greenhouse Effect: [pic] There are certain gases that raise the temperature by trapping the sun’s heat and energy. The Earth’s average temperature would have been about 60Error! Hyperlink reference not valid. colder if it weren’t for these gases. These gases are referred to as “greenhouse effect” because of the way they help to keep the Earth warm. The greenhouse effect makes the Earth suitable for all living things. The Earth might have been freezing or it might also have been burning hot if the greenhouse effect did not occur. However, the presence of too many such gases can cause the Earth to get unusually warmer. The plants would not be able to take such heat and eventually they would have died. The scarcity of plants would cause animals to die of hunger and simultaneously resulting in the end of the human race. Cause of Global warming: Many things contribute to global warming. The causes can be split into two groups: 1. Natural causes. 2. Man-made or anthropogenic causes. 1. Natural causes: Natural causes are causes created by nature. The release of methane gas from arctic tundra and wetlands is one such natural...
