Recommended: Effects of deforestation on earth
Today, the total percentage of forest cover of the earth is approximately thirty percent (“Deforestation”). That is about nine percent of the world’s total surface. The largest rainforest is the Amazon River Basin, located in South America. The Amazon is home to many species of animals, insects, plants and trees. Many of the trees and plants in the Amazon produce about twenty percent of the oxygen on earth, and absorb carbon. However, the Amazon is decreasing in size every day due to the ongoing deforestation of the land. Deforestation is when the forest of the land are cleared or destroyed, in order to be used for other actions (“Deforestation”). The Amazon is twenty percent less than it was about forty years ago (Wallace). In just about every hour to two, land that is larger than two hundred football fields put together is being cleared (Wallace). With the ongoing actions of deforestation in South America, the world could face many effects that will impact every living species.
When deforestation continues to occur, the environment in the world becomes more and more impacted by greenhouse gases. As these greenhouse gases allow sunlight to enter the earth, there is some light that reflects back into space called infrared or heat radiation (“Greenhouse Gases, Climate Change, and Energy”). The greenhouse gases trap the heat radiation from leaving into space (“Greenhouse Gases, Climate Change, and Energy”). When the heat radiation is trapped, it causes the earth’s temperature to rise (“Greenhouse Gases, Climate Change, and Energy”). Among these greenhouse gases include carbon dioxide, which is a gas that trees absorb (“Greenhouse Gases, Climate Change, and Energy”). As the trees absorb the carbon dioxide, they produce and release ...

Deforestation has accumulated many multifaceted controversies over time. The main one, however, is the impact deforestation has on water flow. People have different perceptions on how deforestation affects the flow of water, this lead to a controversy between conservationists and a group of theorists. Many years ago, water was used as a way for almost all the mills to function. Changes in the ecosystem depend on the rate and extent of deforestation and determines how drastic the changes will be.
The Brazilian Rainforest is one of the most unique, vast, and diverse regions of the world. To get a general idea of the diversity of the Rainforest, it makes up a total of one-third of the world forests (more than four million square kilometers), it contains half of the total number of named species in the world (eighty-thousand plant species, 1,500 fish species, and one-forth of the 8,600 bird species), and is the world largest holder of genes (Library 138-139). To say the least, the Brazilian Rainforest is one of the most important natural resources we, as humans, know. It would seem that this knowledge, alone, would also make the Brazilian Rainforest one of the most protected land areas on Earth as well. However, the situation is quite the opposite. The Brazilian Rainforest has been greatly degraded by deforestation since the 1960 , which has led to numerous negative effects both environmentally and socially. This paper introduces the events that opened the door to deforestation, the most immediate causes and effects of deforestation in the Brazilian Rainforest, and my two-part solution to the problem of deforestation.
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 threat since carbon dioxide traps the sun’s heat and radiated light inside the earth’s atmosphere. So, with the increase in carbon dioxide more heat is trapped and thus adding to the effects of global warming. Among the many places where deforestation takes place, Amazon seems to be one of the most affected ones. More than 20 percent of it is already gone, and much more of it is severely threatened due to deforestation . It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year .
The beautiful Amazon rainforest “covers a vast area of more than two and one-half million square kilometers” (The Amazon: Its Developers, Destroyers). It is home to a wide variety of plants and animals, not found anywhere else in the world. Scientists believe that there are still many yet to be found. The Amazon is also home to many tribes who have been there for a long period of time. These tribes accommodate medicine men who know the secrets of the rainforest and the healing properties not yet discovered by scientists. The mysterious Amazon is a long-time treasure that needs to be preserved, because there is so much still to be discovered. However, everyday these opportunities are being taken away from future generations because of the human influence on the Amazon rainforest. Future cures for diseases and the discovery of new life in the Amazon are being destroyed more and more every day. Human influence is negatively effecting the Amazon rainforest.
Thus, deforestation is one of the biggest problems in the world that people have to consider because it has three main long term effects: land desertification, species extinction and climate change. The research paper will discuss and consider the long-term negative effect on the Amazon rainforest which is caused by deforestation. First, the paper will present the causes and effects of land deforestation. Another consideration is endangered species extinction that could affect the Amazon’s biodiversity. Finally, the paper will focus on how climate change and global warming affect the Amazon and what people should do in order to save the forests and solve those problems.
The Amazon Rain Forest crosses several national boundaries in South America, although the majority of it is located in Brazil. It covers over 3,562,000 acres, making it the largest in the world. But globally, over 138,600 acres of rain forest are lost each year to deforestation, 50,000 of those in Brazil alone (Holdsforth), and the world's rain forests are quickly disappearing. Deforestation in the Amazon occurs primarily for three reasons: clear-cutting, fragmentation, and edge effects.
Deforestation is fast becoming one of the world’s worst environmental/geographical occurring disasters known to mankind, and is due to humankind’s greed, ignorance and carelessness when considering the future of our environment.
Nowadays deforestation is the one of the most important and controversial environmental issues in the world. Deforestation is cutting down, clearing away or burning trees or forests. Particularly tropical rainforests are the most waning type of forests because of its location in developing countries such as Indonesia, the Philippines, India, central African countries and Brazil. Deforestation rate in those regions is high enough to worry about, because of large economic potential of forest areas. As the result of causes such as agriculture land expansion, logging for timber, fire blazing and settling infrastructure there might be serious impacts in future. For instance, extinction of endemic species of animals and plants which will be feral, increase of greenhouse gas emissions which may lead to global warming and consecutive catastrophes, destruction of home for indigenous residents which is considered as violation of human rights. Some people can argue with these drawbacks telling that deforestation have more valuable benefits such as growth of economics, production of food and providing better opportunities for life for poor families. However, these benefits are quite temporary and government of that countries and world organisations tries to halt deforestation proposing several solutions. Deforestation problem is especially acute in the Brazilian Amazon, where its rate is much high comparing with other regions. This paper will describe world-wide rainforests, causes and effects of deforestation, and evaluate possible solutions of deforestation in the Brazilian Amazon.
Of all of the issues that effect the planet Earth from a Global Change standpoint, one of the most visible and highly publicized is the issue of rainforest destruction. The loss of this emerald on the planet's crown will end life as we know it, if something is not done...
One reason that people should stop cutting down the rainforest is because many plants and animals are being harmed and losing their homes. The Amazon is home to many more than half of the world’s specimen of plants and animals. Over 70% of the rainforest’s animals and plants live on the subcanopy, or the second highest level of the trees. When you destroy even one tree, many plants and animals, either die or have to find new homes. Many of these tropical plants also have medicinal values such as curing malaria. Sadly, according to Michael Greenwell, the deforestation of the Amazon has led to 26 species of plants and animals and 644 species to be on the brink of endangerment. According to UNEP, about 857,666 square kilometers of land has been lost in one year. The area lost is approximately the size of Venezuela. To keep cutting down trees in the rainforest would be dooming 38 species to extinction. It may seem that the Amazon is vast in recourses and cutting down one tree will not harm much, but if we ...
The Amazon Rainforest or know to many as the “Amazon Jungle” sits on about 2.124 million miles2 and is home to about 10 million species of animals and over 40,000 different plant species. Not including over 2.5 million different insect species. The amazon rainforest is the largest rainforest on earth. The Amazon rainforest is located in South America , it covers much of northwest Brazil and extends into Colombia,Peru and other countries. Part of the Amazon Rainforest is the River that flows through South America and is a big part of the Amazon Rainforest. The Amazon is the seventh oldest rainforest in the world and has existed for about 55 years.
In South America lies the largest and most wondrous rainforest in the world, the Amazon Rainforest. This 1.4 billion acre forest represents over half of the planet's remaining rainforests, and comprises the largest and most bio-diverse tract of rainforest in the world. Ten percent of all known species on the planet are found in this rain forest, most of which have yet to be discovered. For the past century, the Amazon has been gradually decreasing in size due to agricultural expansion, ranching, infrastructure projects, energy exploration and illegal logging. In its current state, the Amazon is losing land equal to the size of the state of Delaware every year.
Everyone needs to respire in order to live, which includes plants and animals. Trees and plants help to regulate the carbon cycle. When the trees take in the carbon dioxide from the environment, they give back to oxygen. When trees are cut down, there is a break in the carbon cycle, and there is no exchange in both oxygen and carbon dioxide which causes a spike in carbon dioxide levels. When these occur carbon dioxide moves in the atmosphere and stores there as a greenhouse gas. “However, deforestation still remains the second leading cause of greenhouse gas emissions, just behind industrial emissions” (Culas). Greenhouse gases disturb the normal regulation of the weather. When greenhouse captures and stores heat problems occur. When the carbon dioxide levels in the greenhouse gases are increased, then the atmospheric conditions becomes unstable, which causes global warming. Global warming is the increase in the temperature of the earth, which is mostly caused by the greenhouse effects. Global warming present itself by affecting the environment by causing drought, floods, change in ecosystem, less fresh water available and other environmental issues. Trees play a big role not only in keeping the soil rich, regulating the water table, providing a stable anchor for soil to lessen soil erosion and providing nutrient rich soil for agriculture but it also helps in the absorption of carbon emission in the atmosphere.
Carbon dioxide (CO2): Carbon dioxide is added to the atmosphere by burning fossil fuels (coal, natural gas and oil), solid waste, trees and wood products, and due to chemical reactions (e.g., manufacture of cement). Carbon dioxide is sequestered from the atmosphere when it is absorbed by plants as part of the biological carbon cycle. Plants are thus acting as the ‘Natural Sinks’ to absorb the excessive CO2 from the atmosphere. This happens during the process of photosynthesis to produce food. Thus deforestation enhances the process of Global Warming.
Deforestation is the amputation of trees from forest areas more swiftly than they can be replanted or regenerate naturally. The fact that trees play an incredibly momentous part in stabilising climate, atmospheric composition and soil structure, removing trees rapidly becomes a major problem. There are numerous reasons behind the felling of trees by mankind. The Amazon basin is a prime example of humans exploiting rainforests. Within this tropical rainforest lie a vast variety of tree species, with many uses, giving humans even more reason to exploit this area.
