Who suffers from Deforestation in the Amazon?
Introduction
Deforestation is a major environmental dilemma not to mention one of the major contributors of global warming, as it constitutes 20% of the emission of carbon dioxide (CO2) into the atmosphere. This is mainly due to the cutting and burning of trees commonly referred to as the ‘slash and burn technique’ used for clearing land. Land settlement, urbanization, cattle ranches, construction of highways after the capital of Brazil was relocated as suggested by Moran (149) all in the name of development. Other causes include mining, oil and gas extraction, cattle ranching and ‘cash crops’. This paper will take a look at the Amazon rainforest which also plays a critical role in the provision of the world’s water supply as the Amazon River runs through it and stretches across a vast geographical area of South America. This rather unique

Although deforestation meets some human needs, it also has profound, sometimes devastating, consequences, including social conflict, extinction of plants and animals, and climate change—challenges that aren’t just local, but global. Deforestation in the Amazon is accompanied with numerous negative socio-political and environmental consequences. These include the extinctions of plants, animals, insects, microbes (bacteria), habitat fragmentation, soil erosion, desertification, climate change and pollution on a global scale primarily due to mining and oil extraction amongst others. the benefits of based on the destruction of the Amazon rainforest,. This paper will explain deforestation, state and describe its primary causes and ask the question of whether or not corporations and markets are the most efficient way to prevent deforestation of the Amazon

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 introduction of cattle ranching industries in the 1960s set the forefront for current Brazilian rainforest deforestation figures. During this time, development subsidy programs encouraged Brazilians to clear rainforest for pastureland and invest in new cattle ranches (Pancheco). Over the last 40 years, Brazil has destroyed 700,00 square kilometers of rainforest, an area about the size of Texas (BBC) (Enchanted Lear...
Nowadays, earth has been facing a series of severe environmental issues which require urgent attention to make the ecology friendly, and global warming is considered as the most vital one. Although some people doubt and disagree that global warming is happening, climate change is real and it is mainly influenced by human activities through the increased production of green house gases such as methane and carbon dioxide. Global warming has the effect of melting polar ice caps and glaciers, which will lead to sea level to go up. Moreover, due to the rise of sea level, the survival of those people who live in islands and coastal cities can ultimately be threatened. Deforestation has been considered to be one of the most important contributing factors to global climate change. Also, since trees absorb greenhouse gases, reduce carbon emissions, and produce oxygen, without trees, the greenhouse effect can be improved tremendously. As World Resources Institute has pointed out in the data, forest loss contributes between 12 percent and 17 percent of annual global greenhouse gas emissions. Thus, what is “deforestation”? Why do people have to deforest? How does it affect environment?
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.
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...
Chapter 1 Introduction 1. Introduction Deforestation is defined as the conversion of forest cover to non-forest land by human activities and is one of the biggest environmental challenges today. Forests all around the world are threatened by unsustainable deforestation but especially severe has the clearing of the tropical rainforests been [6]. Satellite imagery provides an efficient means to retrieve information on the status and extent of forest resource and changes thereof. The large are coverage and high spatial resolution of newly launched optical and radar satellite systems offer new opportunities to remotely estimate and access land cover information on a wall-to-wall basis.
The forests around the world a supply a plethora of community amenities and commercial goods , nevertheless forested terrain progressively is becoming transformed to accommodate other uses, including cropland, pasture, mining, and urban areas, which can produce superior private financial returns. The wide array of benefits the forest provides that vanish directly tied to deforestation have resulted in several policies drafted with the sole intention to reduce the frequency of deforestation. This paper has two primary objectives. First, this paper will review and summarize both the preceding and current research on deforestation. Second, it will emphasize the significance of future research and development, as well as other solutions needed
The Amazon Rainforest is the world's largest tropical rainforest that we have today on our planet. It covers a wide range expanding almost entirely across from East to West of South America. It is most famous for its broad biodiversity and includes the famous Amazon River that is home to rare and diverse species. Today, the Amazon Rainforest is under threat of complete deforestation and has greatly lost more than half of its tropical rainforest due to cattle ranching, soy bean farming, sugar cane plantations, palm oil and biofuel agriculture. The indigenous people are doing their best to fight against the government to protect their land and conserve the rainforest but without capital finance, it is seeming to be an impossible project.
Forests are vital for life and have many important functions. They are home to millions of species and protect soil from erosion. Along with this they produce oxygen which is vital for human life, store carbon dioxide and help control climate. They also provide humans with shelter, food and medicines vital for life.

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.
The Disappearing Rainforests Conserving the rainforest is a global issue of great importance. Tropical rainforests provide a habitat for animals, a unique ecosystem for vegetation, and an abundance of resources for humans, yet they are being destroyed at an astonishing rate. Experts estimate that if these endangered territories continue to be consumed in this manner, no more will be standing in forty years (Rainforest). Examining the social, environmental, and economic costs of the continued destruction of the Earth's tropical rainforests will prove that deforestation for short-term profit is ultimately not viable.
