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
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...
Neanderthal Extinction Neanderthals and modern humans coexisted for well over 100,000 years. Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens. Paleontologists and anthropologists have entertained several possibilities for the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of “survival of the fittest.” What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct.
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).
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.
In all quarters of the globe, you can see some form of popular (pop) culture shape an individual's behavior, sensibility, and perspective on life. Every culture, religion, and ethnicity has changed over time under the influence of pop culture whether it is based on food, clothing items, or simple values and beliefs. Dr. Lawrence Rubin describes popular culture as a, “...banality, it certainly seems meaningless...even potentially destructive. However, if instead we recognize that it is simply an expression of our collective experiences, its importance becomes more clear” ( Popular Culture: We are what we consume,2009). Yet, current pop culture can be seen as a heterogeneous social conception. Particularly, it is always changing and what’s new today will be old by tomorrow. Famous celebrities and latest trends of designs and
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
This psychologist constructed three different types of attachment that a caregiver and child can exhibit, those being, secure, insecure-avoidant, and insecure-resistant (Anderson, 2015). Secure attachment is defined as the caregiver’s promptness to attend to their child’s needs and to be a dependable “safe base” so that the child can wader about their environment worry-free (Anderson, 2015). When the caregiver is no longer present, the child displays emotions of being upset and condenses their exploration, but they eventually calm down because they are certain of their caregiver’s return (Anderson, 2015). Ainsworth’s insecure-avoidant attachment is when the caregiver does not readily attend to their child, and the child independently explores their environment with no regard to their caregiver (Anderson, 2015). The child is very standoffish and shows little to no emotion when the caregiver departs and returns (Anderson, 2015). Insecure-resistant attachment is when the child experiences a great deal of distress when the caregiver leaves, but refuses interaction with them when they return. Here, the child rarely moves around in their environment because they are in extreme distress upon their caregiver’s departure (Anderson, 2015). “One common misconception about attachment is that there is only one figure that can stand as the caregiver, and the chosen one is the mother” (Anderson, 2015). A child can have multiple attachments, but they are not necessarily equal because one is usually the primary, as others are secondary (Anderson,
Attachment theory as defined by Harris and White (2013) examines the connection between infants and young children to their caregivers. Studying attachment is important in understanding behavior because it develops at such a young age and has an influence on all future relationships including dysfunctional family connections, challenges to adolescent peer relationships (Iwaniec & Sneddon, 2001; Reyome, 2010; ). As identified by Ainsworth (1982), there are three categories of attachment which include secure, avoidant, and anxious/ambivalent. In 1990, Main and Solomon concluded that a fourth category should be noted which they identified as being disorganized/disoriented. These different styles of attachment are theorized to have long-term
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.
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,
Restate Thesis: It is important to know our earth is at a high level of risk of pollution and growing changes through global warming.
Although more people are aware of the impacts we have on our environment, there are still people that choose to ignore scientific evidence, or do not fully understand the consequences. Further education and research are critical components in an effort to become more sustainable. Fortunately, younger generations are learning about the need to address environmental issues so that changes can be made to ensure our way of life is sustainable.
The environment today is not in a good condition, Climate change is evident, and oceans are getting polluted. Rainforrest's are decreasing in size due to deforestation and illegal logging. Animals are getting extinct due to the destruction of their habitats. Natural resources are being consumed at very large amounts, and get wasted. There are different ways these problems can be addressed, one option is environmental management. Environmental management focuses on conservation of natural resources, protection of habitats, and impact of humans on the environment. Conservation of natural resources is the smart use of the world's resources by humans, through this waste production is limited, and there will be less garbage in the world. By conserving
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.
Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
