The Environmental Impacts Of Deforestation (Essay Sample)
Directions: Be sure to make an electronic copy of your answer before submitting it to Ashworth College for grading. Unless otherwise stated, answer in complete sentences, and be sure to use correct English spelling and grammar. Sources must be cited in APA format. Refer to the "Assignment Format" page for specific format requirements.
In your course, turn to Lesson 4. Skim through it to refresh your memory. Next, carefully study and review the section titled, “Ecological Challenges Facing Humanity.” Skim through that and then focus on the topic of deforestation.
Relying solely on the material in your course and using your own words, your objective will be writing a short descriptive essay that defines and explains selected environmental impacts of deforestation. As you write, imagine you are talking to a friend who has no knowledge of this topic. In short, write the way you speak, using a conversational tone. Also, try to alternate short sentences and longer sentences to make your writing more readable.
Before, during, or after you’ve completed your essay, be sure to create a title and cite yourself as the author. For example:
Environmental Impacts of Deforestation
Your essay should have 5 paragraphs. Paragraph 1 is your lead paragraph. It will contain an overview of what you have to say about these three topics – disruption of the carbon cycle, disruption of the hydro (water) cycle, and the reduction of species diversity.
Paragraphs 2, 3, and 4, are your body paragraphs. In your essay, paragraph 2 should describe how deforestation disrupts the carbon cycle.
In paragraph 3, you’ll write about how deforestation disrupts the hydro (water) cycle.
In paragraph 4, you’ll explain how deforestation is related to declining species diversity.
Paragraph 5 is your conclusion paragraph. Here, you can describe how you feel about these three effects of deforestation and what we might do about it.source..
Environmental Impacts of Deforestation
Deforestation is the clearing of virgin forests, or deliberate removal or destruction of trees and other shrubberies for commercial, housing, firewood, or agricultural use without reforesting (replanting) and without giving time for the forest to restore itself (Richards, 2002). Trees are utilized for shelter, burned for warmth, transformed into paper products, used as energy sources, and a myriad of other things. However, when trees and vegetation are cut down, it distorts the balance of the entire ecosystem – the carbon cycle, the hydro cycle, and a decrease in species variety. As affirmed by the EPA, a predominant cause of man-made global warming is deforestation, particularly, the clearing of tropical forests, second to the burning of fossil fuels. These disrupt the carbon cycle and subsequently, the hydro cycle. Deforestation reduces species diversity because it deprives species of their native habitat, forcing them to resettle or adapt, but the dire outcome is extinction.
The Carbon Cycle involves the transaction of Carbon Dioxide and Oxygen between animals and plants (Costa, 2009). Humans excrete Carbon Dioxide through respiration whereas plants produce oxygen during photosynthesis. Conversely, humans require oxygen for survival, whereas plants need Carbon Dioxide for photosynthesis. This cycle is perfect in that; it maintains an equal concentration of Carbon Dioxide and Oxygen in the atmosphere. When deforestation occurs, the number of trees decreases; consequently, the rate of Carbon Dioxide absorption steadily decreases because photosynthesis occurrence also decreases (Costa, 2009). This phenomenon, then causes an increase in the concentration of Carbon Dioxide in the atmosphere. In sum, forests have high rates of productivity and an immense capacity to imbibe Carbon Dioxide from the atmosphere. If these are replaced with less productive ecosystems, then removal of carbon in the atmosphere through photosynthesis will be decreased, thus disrupting the Carbon Cycle.
