Abstract
Ever since Dewey McLean (1978) proposed a dinosaur extinction theory
that states that a climatic change killed the dinosaurs, it has become the
single most accepted theory for the dinosaur extinctions within the scientific
community. It is called the dinosaur- greenhouse extinction theory. It says
that a climate change via the greenhouse effect killed off the dinosaurs. My
paper takes this proposed theory and relates it to the world today. Some of the
things that happened back then are also happening now, and if the dinosaur-
greenhouse extinction theory is indeed true, then we are also in danger of dying
from the greenhouse vertebrate killing mechanism, abrupt atmospheric changes,
and the other effects caused by the increased greenhouse effect and people
should know about the consequences of what we are doing to the earth. My paper
examines the similarities occurring in the two time periods and the possible
results that we may soon be facing in the very near future. I am hoping that
exposure to the inevitable danger that we are soon going to be facing, will
spark action and concern within whomever reads my paper. It is a problem that
we all have tended to shrug off and not worry about, but if we don't start
worrying about it soon, there will not be anyone around to worry about. The
time for action is now. We may still be able to change the future.
Humans Soon to Become Extinct? Can it be?
Roughly sixty-five million years ago a tremendous extinction of global
proportions hit the planet earth. This global extinction was so severe that it
has defined the boundary between two periods of geologic history called the
Cretaceous and the Tertiary periods. All but a few mammals on land and water
became extinct. (McLean,1978,p.1) The best known of these extinct animals from
this mass extinction are the huge and mighty dinosaurs. What killed them nobody
really knows and probably will never know, but scientist haven't hesitated to
theorize about it. There have been theories ranging from human involvement to
disease to even aliens. However, of all the theories of the so called K-T
extinctions, the single most accepted theory is called The Volcano Greenhouse
Theory. This theory states that a chain of volcanoes in India, called "the
Deccan Traps", released vast quantities of the greenhouse gas carbon dioxide
into earth's atmosphere trapping heat from the sun, (McLean,1988,p.2) and
turning earth's surface into "the hot, sterilizing, hell of a major greenhouse."
(McLean 1981,p.1) If the dinosaurs did in fact die from the Volcano-Greenhouse
theory, then we are also in danger of becoming extinct from the Vertebrate
Odysseus dealt with his disobedient crew. After an already difficult journey, Odysseus and his crew arrive at Aeolis, where the king Aeolus offers him wind in a bag, which had enough wind to send Odysseus’s ship back home to Ithaca. While Odysseus sleeps, the crew conspires, believing that the bag contained treasure, “Aeolus has lavished these gifts upon him. Let 's have a quick look, and see what’s here, How much gold and silver is stuffed in this bag” (Homer p.142). The crewmen opened the bag and the winds rushed out, taking them back to Aeolis’ island. Due to their curiosity and disobedience, the crew adds years to the journey. But the crew does not learn from the mistake, and the next time they disobey, the consequences were fatal. When they arrive one Helios’ island, Odysseus forbids the crew to consume the cattle of the Sun God. “But swear me a great oath, every last man: If we find any cattle or sheep on this island, no man will kill a single cow or sheep. In his recklessness, but will be content to eat the food immortal Circe gave us” (Homer p.186-87). But while Odysseus is gone, the crew disregards his instructions and feasts one Helios’ cattle. Their consequence was Zeus destroying the ship and the crew, leaving only Odysseus alive. Odysseus wishes to go home, but he cannot control his men’s ignorance. The crew’s disobedience prevents Odysseus from achieving his
To begin I’m going to talk about Rachel Carlson and her ideas. She first starts off with how man has polluted our rivers and many other valuable resources (Postman 2). She explains how the damage humans
An infant’s initial contact with the world and their exploration of life is directly through the parent/ primary caregiver. As the child grows, learns, and develops, a certain attachment relationship forms between them and the principle adult present in this process. Moreover, this attachment holds huge implications concerning the child’s future relationships and social successes. Children trust that their parental figure will be there; as a result, children whom form proper attachments internalize an image of their world as stable, safe, and secure. These children will grow independent while at the same time maintaining a connection with their caregivers. (Day, 2006). However, when a child f...
The human race has a seemingly impossible challenge before them. While many focus on huge social issues such as terrorism and world hunger, which are completely valid and important issues, many have forgotten about the state of humanity’s neighbors within our very planet. Earth is in the midst of its sixth great extinction, keyed as the Holocene Extinction after the current epoch the planet is in. The Holocene Extinction, starting between 9,000 and 13,000 years ago, is the most recent since the Cretaceous-Tertiary mass extinction, during which the dinosaurs were wiped out (Heymann, Chibante and Brooks). Such knowledge of our current ongoing mass extinction event is not well known among the common populace. The simple fact is that the human
In the video, “The dawn of de-extinction. Are you Ready”, Stewart Brand, introduced us to term de-extinction, the process of creating an organism that is extinct, and the global benefits of this process. In addition, Mr. Brand mentioned how humankind didn’t realize the biological impact of extinction until 1914, when the last female passenger pigeon died at the Cincinnati zoo. Moreover, how the number of this specie went from five billion birds to zero in couple decades, because of the out of control commercial hunting and other human activities. On the other hand, this specific consequence of the commercial hunting made people realize that the extinction of other species, like the American bison, will happen and needs to stop. Subsequently,
Mary Main was Ainssowrth student. She therefore introduced another fourth category of attachment styles with her attachment studies with adults. During her longitudinal research project alongside her colleague Goldwyn on middle class children’s attachment styles, they found that about 79% of the time attachment styles remained constant from 18 months to 6 years of age (in Brandell & Ringel, 2007,). However in their observations about 5%) that did not fit into Ainsworth’s classification of attachment styles, which they called ‘disorganized/disoriented attachment’ (Main & Solomon, 1986, 1990). These children were fearful and engaged in repetitive or aggressive behaviors. Their behaviors at reunion were unpredictable. They displayed contradictory behavior patterns such as approaching and then suddenly avoiding or exhibiting misdirected behavior patterns such as crying when the stranger leaves or stereotypical behaviors such as rocking, hair pulling or freezing. The mothers of these children were either depressed or had unresolved grief due to early loss of own parents (Main & Solomon, 1986). In this type of attachment, there is no or very little organized strategy to cope with stress and to form an attachment relationship with the caregiver, because here, the attachment figure is the direct cause of distress or fear. An abusive, abandoned and frightening caregiver is the source of fear and the protector at the same time. The infant shows signs of distress and displays avoidant and inconsistent reactions in the presence of the caregiver (Bakermans-Kranenburg & van IJzendoorn, 2007; Stams et al, 2002).
Over a century ago, humans fought animals for dominance of the landscape and we regrettably won, now they’re in need of our protection. The Government and Organizations have come to the rescue of wildlife species all across the U.S. Their main goal is to protect wildlife species from over harvesting and also their loss of habitat due to industrial and residential development. The beauty and curiosity of wildlife captivates all of us for different reasons. For certain species, they are the link to our existence Animals are not being hunted into extinction because the government is protecting certain wildlife areas and are controlling the animal populations within those certain areas. While increasing a wildlife species population and removing from the endangered species list, a predator such as the gray wolf, is sure to be seen as a success to some and a threat to others.
The National Wildlife Federation lists an endangered animals as a genus that may be eradicated by leaving an insufficient quantity to reproduce or obliterating the species in it entirety ("Endangered animals act," para 1). In the United States alone there are 70 mammals that are recorded as endangered; however the foreign number exceeds 250 (US Fish and Wildlife Service, 2014). The extinction process could be correlated to a natural route; however extinction may also transpire due to environmental differences. Climate variations producing even slight changes in characteristics may have an extreme consequence on an endangered species. Loss of habitation also impacts species causing them to becoming imperiled. On occasion ailments are distributed from domestic animal; due to the loss of habitation wild animals to come in contact with infected animals. For example Siberian tigers have development distemper from domestic dogs; and this has triggered the tigers to lose their fear of humans. This proves to be hazardous when the tigers approach villages and roads and are killed; furthermore the disease may cost the tigers their lives. (Dell’Amore, 2013). Many of the vanishing animals are poached for varies elements that may be utilized in traditional treatment. The African rhino is on species that is being significantly exploited for their horns; in Vietnam and China the horn is thought to treat everything from hangovers to cancer (O’Neill, 2013). In addition, the introduction of an exotic species afflicts endangered animals, and the overexploitation of animals initiates noteworthy reductions in populations. If an animal is not able to adapt to changing variations it could be disastrous to a species.
This theory also heavily relies on the idea that in order to modernize, the country must Westernize and lose their traditional culture. It is then proposed that although in present day many societies are modern, its does not mean they are all the same.
Psychologist, Mary Ainsworth expanded upon Bowlby's original work. She conducted a study labelled the ‘Strange Situation’. In the study, based upon the children’s reactions, Ainsworth described three major styles of attachment: secure attachment, ambivalent-insecure attachment, and avoidant-insecure attachment. Work by Stroufe and Waters in 1977, further supported Ainsworth's attachment styles and have indicated that attachment styles also have an impact on behaviours later in life (Birns, 1999, p. 13). Researchers have found strengths in attachment patterns established early in life can lead to a number of outcomes. For example, children who are securely attached as infants tend to develop stronger self-esteem and better self-reliance as they grow older. These children also tend to be more independent, perform better in school, have successful social relationships, and experience less depression and anxiety (Birns, 1999, p. 13).
John Bowlby’s attachment theory established that an infant’s earliest relationship with their primary caregiver or mother shaped their later development and characterized their human life, “from the cradle to the grave” (Bowlby, 1979, p. 129). The attachment style that an infant develops with their parent later reflects on their self-esteem, well-being and the romantic relationships that they form. Bowlby’s attachment theory had extensive research done by Mary Ainsworth, who studied the mother-infant interactions specifically regarding the theme of an infant’s exploration of their surrounding and the separation from their mother in an experiment called the strange situation. Ainsworth defined the four attachment styles: secure, insecure/resistant, insecure/avoidant and disorganized/disoriented, later leading to research studies done to observe this behavior and how it affects a child in their adolescence and adulthood.
A number of different theories have been assessed throughout the course of this research to attempt to reach a conclusion as to the reason behind the extinction of the Tyrannosaurus Rex. Although all arguments are credible, and supportive with educated information and data, the most conclusive theory of all is The Alvarez Asteroid Impact theory.
Restate Thesis: It is important to know our earth is at a high level of risk of pollution and growing changes through global warming.
Many people assume that the environment is not in danger. They believe that as technology advances, we do not need to worry about renewing natural resources, recycling, and finding new ways to produce energy. They state that one person in the world does not make a large difference. In reality, each individual's contribution greatly affects our environment. Our natural resources are slowly disappearing, and we must work together to save them and the Earth from ruin.
Pop culture is a reflection of social change, not a cause of social change” (John Podhoretz). It encompasses the advertisements we see on T.V, the clothes we wear, the music we listen too, and it’s the reason Leonardo DiCaprio has not won an Oscar yet. It defines and dictates the desires and fears of the mainstream members of society; and it is so ingrained into our lives that it has become as natural as breathing. Moreover, adults never even bat an eyelash at all the pop culture and advertising that surrounds them since it has become just another part of everyday life. Pop culture is still somewhat seen as entertainment enjoyed by the lower class members of society; but pop culture standards change over time. A notable example of this is the sixteenth century author, William Shakespeare, since his works were considered pop culture, entertainment that could be enjoyed by everyone, but now they are considered literary classics. While pop culture encompasses most aspects of our lives, its influence is most obvious through each generations reaction to media,
