Deforestation in the Amazon Rainforest: Human degradation and its consequences

Deforestation is a word that displays an image of cruelty against nature. In any language, and on every continent, the word deforestation is frowned upon by all social classes, however why it is still happening? The consequences of this act that involves human beings willing to cut down trees, burning plants, and destroy habitats of animals are just actions to satisfy some human being. The Amazon rainforest covers various countries where 60% is in Brazil, and 13% in Peru, and produces 20% of total oxygen in the world. Unfortunately, the political leaders of the countries that make up the Amazon jungle are not interested in its full protection and do not realize that the world health is in their hands. The main purpose of deforestation is to expand, build, and work to advance political purposes. One example is the relentless pursuit of oil, which does nothing but to destroy wildlife, and by drilling the land it exposes soil to sunlight which creates erosion. That example reminds me a phrase from the philosopher Machiavelli, in which he thinks that end justifies the means. His idea suggests that if the objective is good, then it doesn’t matter if the way we achieve it is bad, wrong, or evil. Why do people continue supporting deforestation? This question has many answers, but relies on a behavior problem, lack of respect, and necessity to survive, mostly from very low-income humans. The government allows deforestation to expand, and this creates the following main consequences: Disruption of hydrologic cycle, erosion of soil, loss of biodiversity, and the increase of Carbon Dioxide in the atmosphere.
The tree is an essential element in the forest, yet is a key part in the hydrologic cycle. This happens because water is absorbed by the root, and then it is removed by perspiration from their leaves. If trees are being diminished, then the hydrologic cycle will slow its normal activity. According to Ronald W.A Hutjes from the Wageningen University research center, he stated that thanks to several campaigns documented in the mid-eighties which documented surface-atmosphere exchange processes, we can proof that deforestation indeed disturb the Hydrologic cycle. The rapid growth of the Planetary Boundary Layer (PBL) over pasture in dry season has been shown to lead to earlier formation of cumulus and consequent reduction in solar irradiation used satellite image to show that shallow cumulus formed mostly over cleared areas in Rondônia (a severed deforested Brazilian state)(Hutjes 120). On the other hand, the inverse of this reaction occurs in wet season, when warmer night temperatures over forest lead to rainfall production from moisture earlier in the day than over pasture. Even though trees are not the only water supplier by condensation process to the clouds, if a huge amount of trees are being diminished like is happening now in Brazil and in Peru, this climate changes...

Deforestation of the Rainforest

1243 words - 5 pages Rainforest biomes are characterized by high rainfall of 1750-2000 mm (68-78 inches) annually. They have tall, dense jungles because of competition for sunlight. Rainforests are often found in tropical climates (regions between the Tropic of Capricorn and Tropic of Cancer) and they are home to the majority of the world’s species. They contain one-half to two-thirds of the world’s surface (Lindsey Rebecca). The climate of rainforest biomes is very...

Deforestation In The Amazon Rainforest Essay

970 Words4 Pages

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 Amazon’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,
“The claim that the rain forests are being destroyed "at a rate of 20 football fields a minute" is false . In addition, claims that the Amazon serves as the "lungs of the earth" and that over "450 species" are
