Deforestation is the cutting down and burning of trees. The Brazilian
government has let deforestation to take place in the Amazon
rainforest because it carries lots of investments into Brazil; mostly
by multi-national companies (MNCs).Also deforestation of the Amazon
rainforest has bought factories, power stations and work for people of
Brazil. The deforestation of rainforest areas has improved the
infrastructure of Brazil, many highways and roads have been made for
the transportation of wood. There is worldwide demand for woods such
as mahogany, therefore it seems deforestation must take place.
Some residents of the area want more land to grow crops on as an
outcome they clear out the forest. Also Brazil’s population is
increasing faster which means that more space is required to grow
crops on.
There are many negative consequences of deforestation for the
environment (locally and globally). For example, deforestation causes
global warming which changes the climate (weather) throughout the
world. When tresses are burnt CO2 is produced and because CO2 is a
greenhouse gas, it rises in the atmosphere and blocks the heat rising
away from earth. This causes floods because the heat that is trapped
inside the earth can melt the ice blocks in the oceans; also trees
need water from the soil for photosynthesis (transportation). This
water is afterwards condensed into the atmosphere as water vapour
which forms rain.
So fewer tresses would mean less rainfall, which means the rainforest
could become dry and possibly one day even a desert. Deforestation
also damages the soil of the rainforest, the trees protect the soil
but when the trees cut down the rain washes the soil into rivers
(river pollution). This increase erosion and decrease soil fertility
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.
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.
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.
Alina Bradford from Live Science, explained in her article about deforestation and how there are different causes of deforestation such as, selling trees for products such as paper, homes, house hold furniture, and other house products. She also states that other causes of deforestation are making room for agriculture purposes, and to create room for cattle ranching as well. On the downfall though there are disadvantages of deforestation as well too as she explains. One of them in fact is deforestation is contributing to climate change and also the greenhouse effect too as well by emitting a great amount of carbon dioxide (CO2) into the earth’s atmosphere. The effect from that happening is carbon dioxide is a greenhouse which absorbs heat from the sun and doesn’t let it escape into space. As that doing so, the Earth is heating up each year due to deforestation. From that, it will cause global warming and climate change too. There are causes and different purposes for deforestation but there are significant effects that could end up due to deforestation based on Alina Bradford’s
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...
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 .
By definition, deforestation is the permanent destruction of forests in order to make the land available for other uses. Such as the conversion of forestland to farms, ranches, and urban use. Food and Agriculture Organization of the United Nations has reported that an estimated 18 million acres of forest are lost each year and about half of the world's tropical forests have been cleared. Also, according to Bastien Sachet, “…tropical deforestation is responsible for approximately 20% of world greenhouse gas emission…Every year, 13 million hectares of the world’...
In 2000 the population was 174.5 million people and now it is 200.4 million. The majority of this growth is people that live in the amazons. Government started deforestation for two main reasons, clear more land for houses and roads, and to have more jobs and the selling of wood. The US population increased from 247.2 million to 318.9 million in the last 26 years. It tells us that the deforestation in Brazil is being affected a lot in the last 16 years, and experts wait for more increased of population in Brazil caused by the deforestation.Deforestation of tropical forests affects not only the plants and animals of these regions but also their human inhabitants. The Indian populations of Amazonia are successful managers of the forest. Long ago, they discovered the secrets of sustainable use of its resources. I discuss the knowledge and management of the forest environment exhibited by the Yanomami and Kayapo Indians of Brazilian Amazonia and the importance that their knowledge and their presence as part of the forest ecosystem has for us all. Not only is this forest ecosystem now being destroyed at a rapid rate, but we (the non-Indians) do not yet know how to care for and make use of whatever areas of forest will be left when this process of destruction is brought to a
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.
Countries such as Brazil and Indonesia have been greatly affected by deforestation with well over two million hectares of naturally forested land now rendered barren (See appendix 1).
Deforestation is a widely used term, but one with different meanings. Disturbance deforestation refers to all man made disturbances that alter a forest, these are the most common. This argumentative essay discusses the positive and negative aspects of deforestation. In the first part of the essay the pro arguments of deforestation will be discussed. For example, the issue of Global population and how forests are being used, land use and the ways forests contribute, wood use, forest growth, destruction and the reasons for cutting down the trees. The second half of the essay will cover the issues that are harmful to the environment because of deforestation. Many environmental issues take place everyday; a big question that arises, is if the global economy will ever finds middle on the issue of forest thinning. If deforestation was used only in the most crucial of times, the world might become a better place.
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.
Rainforests, should we cut them down or not? Probably one of the biggest questions the world has to overcome. Sure, rainforests supply us with a lot of resources and we could surely not live without cutting some of them down, but should we be cutting them down at the rate we are? To be exact, the statistic estimates 1.5 acres of natural rainforests are being destroyed every second. While this practise supplies us with resources like timber for furniture, it also reduces the amount of oxygen supply.
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.
Commercial logging for lumber or fuel supplies is another factor. The cutting down of trees for a profit is also depleting our forests. Another travesty of commercial logging is the damage caused to other trees that surround or are in the path of the trees being harvested. Logging also increases the destruction to forests in the event of fire as outline in the article entitled “Deforestation in Brazilian Amazonia: History, Rates and Consequences” written by Philip M. Fearnside, “Logging greatly increase the susceptibility of forest to fire. Once fire enters it kills trees and increase...
