Deforestation In The Amazon Rainforest Essay - 970 Words

Introduction: Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious†¦show more content†¦In whichever case, the land would take years to grow back to being what it was. Therefore, the amount of trees cut by deforestation is still greater than the amount of trees regrown by reforestation and thus effecting Amazonâ €™s plant biodiversity. A prediction by the World Wildlife Organization states that by 2030, 55% of the Amazon’s Rainforest could vanish if current deforestation rates are maintained . Meaning half of its plant biodiversity could be gone by that time. Deforestation not only harms plant biodiversity it also harms the animals. Many living organisms are very sensitive to their environmental changes. The loss of their own niches would compel them to join other organisms in their niche. In this case the organisms who lost their niche would act as the invasive species and depending on other climatic or ecological factors these two species would cease to coexist. One of these two species might go extinct due to competitive exclusion or, as Darwin’s theory implies, survival of the fittest. Con arguments: Marc Morano, a correspondent for the TV magazine, American Investigator, states that, â€Å"The claim that the rain forests are being destroyed at a rate of 20 football fields a minute is false .

12 Angry Men: An Illustration of Concepts of Organisational Behaviour Introduction In 1957 Sidney Lumet’s 12 Angry Men was published (Lumet, 1957). Now, 55 years later, the movie’s teachings still hold most of their truths. The events shown in the movie can be scientifically explained using concepts of organisational behaviour. Although some of these concepts did not even exist by the time the movie was made, the movie still is an excellent case to study and illustrate them. The reason for this is the isolation of the movie’s characters. All events in the movie are triggered by the characters only. There are no external influences nor is there the possibility for the characters to leave the scene.

Since Weber refers to political domination, in organizational behavior other concepts of leadership are applied. One of the more recent models of leadership however again emphasizes the importance of charisma. This model is called transformational leadership and has been coined by McGregor Burns (Huczynski and Buchanan, 2007, p. 718). It stresses the importance of charismatic leadership which is described as [...] a leader–follower relationship in which leaders create a strong personal bond with followers. (Caldwell et al., 2012, p. 177) This bond is created because the followers believe that the leader has an extraordinary character (Caldwell et al., 2012, p. 177). He often goes beyond simply making instrumental, outcome choices and also makes normative value based choices and highly values moral (Caldwell et al., 2012, p. 176). By doing so he creates a common vision for his followers. He motivates them to work towards achieving the vision and putting this before their self- interest. Brass and Avolio (Huczynski and Buchanan, 2007, p. 718) state in their model of transformational leadership also the leaders ability to encourage others to see things from different, new perspectives as well as the ability to develop individuals to higher levels. Juror no. 8 has all characteristics of a transformational leader.

The Lovely Bones Essay Example For Students

The Lovely Bones Essay Many people believed that the bone is static and inert, but this idea isincorrect, the organic and mineral components of the bone matrix are continuallybeing recycled and renewed through a process called remodeling. This processgoes under way throughout life, as part of normal bone maintenance. Boneremodeling plays a key factor between the activities of osteocytes, osteoblasts,and osteoclasts. In the adult stage, osteocytes are continually removing andreplacing the surrounding calcium salts. But osteoclasts and osteoblasts alsoremain active, even after the epiphyseal plates have closed. For the most parttheir activities have a balance. As one osteon forms through the activity ofosteoblasts, another is destroyed by osteoclasts. In young adult, approximatelyeach year one fifth of the adult skeleton is demolished and the rebuilt orreplaced. The turnover and recycling of minerals give each bone the ability toadapt to new stresses. The mechanism that controls the internal organization andstructure is osteoblast. Whenever a bone is stressed, the mineral crystalsgenerate electrical fields. Osteoblasts have an attraction to these electricalfields, and once they are in this area they begin to produce bone. Since bonesare adaptable , their shapes reflect the forces applied to them. Heavilystreeled bones become thicker and stronget, whereas bones not being accessibleto ordinary stresses will be deteriorated. Therefore is important to exercisedaily to maintain a normal bone structure.
