Deforestation in the Amazon Rainforest: Effects
This report will discuss the effects of deforestation in the Amazon Rainforest on the people and Environment and suggest possible solutions for deforestation. The Amazon Rainforest located near Brazil is being cut down at a rate of roughly 10,000km every year according to Source 1. Deforestation is affecting the entire planet.
One reason that the Rainforest is being cut down is for logging, according to Source 3 logging accounts for 10% of rainforest deforestation. The timber from logging is often used for paper, tables and and sometimes fuel. The rainforest has remained untouched for many years before companies came for wood, because of this there are large amounts of unspoilt plants and

trees. These trees are being cut down to supply the world. In most cases the logging companies are not replacing the trees that they're cutting down. Companies around the world often need cheap wood to make products at a cheaper cost. The Brazilian authorities have began to place limits on how much wood can be taken from the rainforest. However, this has started "illegal logging companies". These companies cut down more wood than they're allowed so that they can earn a larger profit. Another reason the rainforest is being cut down is for mining.
According to Source 3 "other" activities (including mining) take up 5% of reasons for for deforestation. As the rainforest is mostly untouched there is still minerals to be excavated from under the ground. This has led to mining companies buying areas of the rainforest to excavate it.
Some effects of deforestation are that, according to Source 4, the cutting down of trees is adding to global warming as trees take in carbon dioxide produced by humans and give out oxygen for us to breathe. Burning trees also produces greenhouse gases which are released into the atmosphere. With less trees, there will be more carbon dioxide going into the atmosphere which will lead to more heat being trapped, heating up the planet further - resulting in the ice caps melting and animals like the Polar Bear going extinct.
Effects of deforestation for mining are that tribes who have been isolated from the outside world will have their land and lives disturbed as people come into the rainforest to mine for minerals. Tribesmen/woman upon joining modern life often become unemployed and have drink and drug problems. Sometimes foreigners can also bring over diseases which the Tribes have never encountered, thus not being immune and often dying. Roads would also have to be made which would mean people possibly coming to the Amazon Rainforest and disturbing the tribe's way of
life. One strategy adopted in response to deforestation was to designate zones where no-one would be allowed to visit like National Parks. These zones would mostly include isolated tribes and their land so that they can live normally in the rainforest. These zones would also include the areas of endangered species and their hunting ground. Anyone trespassing in these zones would be arrested. This was put into place by the Brazilian Government. Another Strategy adopted in response to deforestation was to limit the amount of wood that logging companies could cut down and sell. Over-logging is still an issue however as people still cut down large amounts illegally. Anyone caught doing this can be fined. The Brazilian Government has setup an organisation specifically tackling this issue to enforce this law.
The main reason deforestation happens, is because of farming. They need to clear out land in order to plant crops and vegetables. Another loss from deforestation is that many animals lose their habitat. The loss of animals habitats will lead to migration, or possibly even extinction. And when this happens this will ruin the food chains which will affect even more animals.
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 .
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.
Most of the positive implications of deforestation are for the economy. Rainforest land is cut down and converted into a monoculture rubber plantation, to provide necessary resources for humans, in this case rubber. There are not a lot of positive implications about deforestation and they are mostly overruled by the large
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.
Firstly, one major similarity in deforestation between Brazil and Indonesia is the amount and rate of the forest devastation. In Indonesia, approximately 50 percent of Sumatra’s forests have massively been destroyed during the period of 1985 to 2008, which have entirely transformed the outlook of Sumatra Island (Watts, 2013). According to Butler (2013), almost 158,000 square kilometers of Indonesia’s forest were diminished by the end 2012. Moreover, the rate of deforestation in Indonesia has continuously increased over the next few decades. Similarly, the amount of forest loss in Brazil was also considered to be the second highest from the year 2000 to 2012, which was approximately 361,000 square kilometers (Butler, 2013). The deforestation rate in Brazil has risen up over 28 percent from the period of August 2012 to July 2013, especially in some states near the Amazon regions that have the total amount of deforestation around 5,843 square ki...
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.
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 ...
Deforestation has an effect on the carbon cycle which is also known as the “Greenhouse effect and Global warming.” See the
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.
Mining in the Amazon Rainforest is bad because it ruins one of purest, most untouched places in the world. If mining is allowed, the place would lose the traces of what it was and could have been. The Amazon counts for 50% of the remaining rainforests. We would also lose a lot of oxygen because the Amazon produces 20% of oxygen in the whole 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.
Mining is also is a major factor of deforestation. In order to get to all the metals, minerals, and rocks deep in the Earth’s crust, there will have to be an extraction of all vegetation above ground. Not only do humans need room for mines, but also for the trucks and equipment. The Amazon is considered to be very rich in minerals such as: copper, tin, bauxite, nickel, iron, manganese, and gold. As extraction technologies improve, it is more likely that the scale of Amazon mining will

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...
