When the Portuguese landed in Brazil 500 years ago the sight that greeted them was of a huge rain forest, which then ran along much of Brazil’s Atlantic coast. In more recent times, there has been an outcry over the destruction of the much larger Amazon forest. But its devastation is nothing compared to Brazil’s Atlantic forest. About 86% of Brazil’s Amazon forest is still intact but only about 7% of the Atlantic forest remains. In this paper, I will explain why the Atlantic forest was destroyed, why deforestation happens, and the effects of rain forest destruction and the effect it is having on the Earth.
Much of the Atlantic forest was destroyed to make way for farmers to plant sugar, coffee, and other crops, and later for growing cities like Sao Paulo and Rio de Janeiro. Between 1990 and 1995, 1.2 million acres were destroyed (Reid, 2000).
Clearance for living space, commercial logging, for farming, roads and railways, forest fires, and mining and drilling are all connected with deforestation. People have been living in and around tropical rain forests for tens of thousands of years, taking what they needed from the wealth of natural resources available without compromising their environment. However, in the last 200 years populations have expanded, requiring more and more space for housing and farming. For example, Costa Rica has a population of over 3 million people, heavily concentrated in the Central Valley. Well over one-half of the national population lives in this area, which represents only 5% of the country’s land area, and almost one-half of the population is considered to live in urban areas. The population growth rate is relatively high and if it continues at the present rate, the population will double in only 28 years (Hecht, 1989). Commercial logging can occur selectively, where only the economically valuable species are cut or by clear cutting, where all the trees are cut. Commercial logging uses heavy machinery, such as bulldozers, road graders, and log skidders, to remove cut trees and build roads.
Another cause of deforestation is known as shifting cultivating. Indigenous people have farmed the rain forest, cutting down trees to allow cultivation of crops and grazing space for animals, and moving on when the soil becomes less fertile. This is no threat to the forests; provided that used areas are left to regenerate for long periods before repeating the process.
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...
The term "deforestation" refers to the clear-cutting of large sections of primary or original-growth forest, which causes the loss of native species of plant and animal life. This clearing of land is mainly due to agricultural needs, such as farming and cattle ranching, but also occurs to support logging and mining companies. The effect of the loss of forest is most obvious in the loss of native species. Eugene Ng, of the Hong Kong Technical Institute, explains that the "destruction of habitat forces species out of areas, or causes them to die." Other factors, according to Ng, "further restrict their range, exposing them to disease and predators."
The research paper will discuss and consider the long term negative effect in the Amazon rainforest which is caused by deforestation. First, the paper will present the cause and effect of land deforestation. Another consideration is endangered species extinction that leads to effect the Amazon’s biodiversity. Finally, the paper will focus on how climate transformation and global warming affect the Amazon and what should people do in order to save the forests and solve those problems.

Brazil, a country of natural resources running everywhere needing saving, destroyed everyday by humankind. with 2/3’s of the Amazon forest home in brazil, we must keep an eye on how it is being sustained, what is being done to keep it safe and when we believe we will be able to not only stop deforestation, but grow back the earth’s creatures natural habitats. The sheer beauty of our world is worth trying to help our ecosystem and helping the environment and ensuring its sustainability.
No matter where a person lives, even if it is not near a rain forest, the complete destruction of rain forests will affect living conditions. For years rain forests have provided countries around the word with valuable resources, minerals, lumber, and energy. In Brazil alone the rain forests contains 45% of Brazil’s hydroelectric power. The minerals found in the rain forests of Brazil are estimated to value 1.6 trillion dollars, while the lumber that the rain forests can provide total 1.7 trillion dollars (“In the Forest” 1). Nutrients from decomposing organisms can be found throughout rain forests, including in soil and in trees. To continue destroying forests also destroys the important materials that they are providing to humans.
The Amazon is a vast region spanning across six South America countries Brazil, Bolivia, Peru, Ecuador, Colombia, and Venezuela (Walker, & Cesareo 2014). The Amazon is one of the most developed rainforest of anywhere in the world. Over two-thirds of all the fresh water and 20% of the earth’s oxygen are produced in the Amazons (wcupa.edu). Despite the vital role of the Amazons, carless practices continue the rapid deforestation of the ecosystem. (Mainville, et al, 2006). The main causes of deforestation include unsustainable logging, agriculture, invasive species, fire, fuel wood gathering, and livestock grazing (Thompson, et al. 2013). The widespread of this issue is of importance in global policy processes, which deals with biodiversity, climate change, and forest management (Thompson, et al. 2013). The Ecuador has some of the highest rates of deforestation; an estimated 3% of the land is yearly destroyed (Mecham, 2001). “The Ecuador’s interandean basin native vegetation has been practically eliminated since colonial times, replaced by crops, pasture, towns and cities, and exotic tree plantations. This area suffers severe soil erosion problems even today” (Mecham, 2001). The continuum of deforestation issues continues to destroy the ecological habitat of the Amazonian Indians (Mecham, 2001). In the area of Napo River Valley West of the Ecuadorian Amazon, deforestation has resulted in an abrupt end of harmony between man and nature (Mainville, et al., 2006). The desire for economic profits continues to fuel the already alarming rate of the Amazon. According to the Rain Forest foundation, “When Texaco entered the Ecuadorean Oriente in, 1967; the area was considered the most biodiverse place on Earth. Since then, more than 20 billi...
Roughly half of Bolivia is covered in forests. However, this amount is decreasing yearly due to a variety of economic and social causes that are representative of the developing world. In the last decade, Bolivia is one of the ten countries with the highest rate of forest loss (Muller, Muller, Schiehorn, Gerold, Pacheco). Until the mid 1980’s, the Bolivian forests were unaffected because the country’s revenue came from mining and agriculture within the communities (Muller, Pacheco, Montero). However, the collapse of tin mining led the unemployed miners to settle and begin farming. Also around this time, mechanized agriculture started to be favored because of the ability for greater trade. The three major sources of deforestation in Bolivia
Governments in these countries need to stop thinking of forests as a renewable resource. The rate at which they are harvesting these areas drives them beyond the boundaries of sustainability. The efforts required by reforestation may not initially be cost effective, but it will result in not only the survivability of the environment, but of the country’s economy. Widespread awareness of these ideas will help fight against the natural human tendency towards instant gratification and short-term goals. Different methods of logging can be utilized to allow the rainforests to survive and regrow naturally and at a sustainable
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.
Deforestation began with man’s ability to manipulate his environment. Wood has always been a primary source for shelter and has been affected by human expansion. As the worlds population grew, so to did the need for wood to make housing. As cities grew so did the demand for space to accommodate the growing population. Throughout history and even today, man has manipulated the environment affecting it’s resources.
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 planets 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. At its current state, the Amazon is losing land equal to the size of the state of Delaware every year. The destruction of this forest releases 340 million tons of carbon per year according to the World Wildlife Foundation, or WWF, which in turn cause climate changes everywhere around the world. Undiscovered species can hold the key to curing a plethora of diseases, but if those species become extinct those keys are lost forever. If nothing is done to prevent this, the world’s treasure trove of bio-diversity will cease to exist, creating irreversible damage to not only the South American people but also the rest of the world.
People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Although tropical forests are largely confined to developing countries, they aren’t just meeting local or national needs; economic globalization means that the needs and wants of the global population are bearing down on them as well. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation.
Scientists themselves are just beginning to understand the serious problems caused by deforestation. Deforestation occurs all over the world by all types of people. Peasant farmers even add to the problem because in most tropical countries the farmers are very poor only making between eight hundred and fifty four hundred dollars annually (NASA Facts). Therefore, they do not have enough money to buy what they need to live therefore they must farm to raise crops for food and to sell. In these poor countries the majority of people are peasant farmers this farming adds up to a great deal of deforestation. These farmers chop down a small area of trees for there plot to farm on and burn the tree trunks (NASA Facts). The combined number of farmers maintaining this process creates a great deal of clearing and burning of the land they need to cultivate, which results in land being treeless. Commercial logging is also another common form of deforestation. This commercial logging wipes out massive amounts of land sometimes deforesting several miles at...
Deforestation is the elimination of existing trees from the earth; attributable factors include urbanization, logging, ranching, and farming and to some extent land speculation. Land speculation can be included as cleared land is more valuable than forested land. Deforestation, done in the name of progress, and the long-term, devastating effects of it, is killing our planet.
