Deforestation and Biogeochemical Cycles. Literature & Language Essay

Essay Instructions:

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, write 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.
Be sure to create a title and cite yourself as the author. For example:
Environmental Impacts of Deforestation
Jennifer Croft
Your essay should include five paragraphs, as follows:
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 hydrologic (water) cycle, and the reduction of species diversity.
Paragraphs 2, 3, and 4, are your body paragraphs.
Paragraph 2 should describe how deforestation disrupts the carbon cycle.
In paragraph 3, you’ll write about how deforestation disrupts the hydrologic (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 the three effects of deforestation discussed, and what we might do about it.
It’s permissible to use direct quotes from your reading, but don’t use too many. One to three such quotes should be your limit. Be sure to put a direct quote in quotation marks. For example: According to Smith, “Carbon dioxide is both our friend and our enemy.”

Deforestation and Biogeochemical Cycles
Carbon, water, and nitrogen cycles are some of the primary biogeochemical cycles that shape the life of living things on earth. Carbon dioxide is crucial to photosynthesis on plants as well as animals. Disrupting the carbon cycle would later affect life as we know it. The principal causes of carbon cycle disruption are deforestation and emissions from burning fossil fuels. Clearing forests not only leave the land bare but also the capability of carbon dioxide absorption reduces, as there are no trees to carry out the activity. Disruption of the water/hydrological cycle can be linked with deforestation (Lesson 4). Trees are responsible for extracting water from the ground and returning it to the atmosphere. Clearing trees means the water will not be released into the air and thus an imbalance in the hydrological cycle. Species diversity is the measurement of biological diversity located in a particular ecological environment. Loss of biodiversity is the extinction of a species in a global manner or a particular habitat. This essay tries to cover these topics and their relation to the current ecological challenges. Deforestation affects hydrological, carbon, and plays a part in biodiversity loss.
Effects of Deforestation on The Carbon Cycle
The carbon cycle involves the movement of carbon from one place to another. With every life form on earth is made up of carbon, it is crucial to life. It is produced by both human-originated sources and other natural methods into the atmosphere as carbon dioxide. For instance, gases that contain carbon diffuse from the ocean surface into the atmosphere while other significant sources of large amounts of carbon dioxide result in volcanic activity. Humans release carbon into the air in several ways that include deforestation, burning fossil fuels, and wood. 
Deforestation affects the carbon cycle, especially in cases of clearing of global forests. Vast forests across the globe absorb significant amounts and release oxygen into the atmosphere. Tropical forests are crucial to the global carbon cycle, and continuous clearing is significantly causing global warming. Rotting and other dead plants release carbon dioxide that adds up to the greenhouse gases. Deforestation and land use also affect the reflectivity of the earth's surface, causing too much heat in the atmosphere. With deforestation increasing carbon dioxide levels in the atmosphere, what happens after it is released into the atmosphere and what are some of the removal methods that can be used to minimize high carbon dioxide effects on the environment?
Carbon dioxide is first dispersed rapidly across the atmosphere, plants, and the upper layers of oceans. It is then relocated among the various carbon dioxide reservoirs of the carbon cycle, for instance, soil, rocks, and the lower levels of the ocean and seas. Some of these processes occur at slow rates that take hundreds of years. The distribution of carbon dioxide takes a long time to balance the cycle. This means that carbon dioxide is recycled back to the atmosphere continuously in countless periods. Carbon dioxide exists in million...
