AMAZON DEFORESTATION
Hello class welcome to my speech today i will be saying why we should not be cutting down so many trees in the amazon.If you don't know what i mean it is called deforestation well since we are talking about the biggest forest in the world amazon deforestation.
First of all you may ask why do we cut these trees. We cut down trees because we sell it to people, we use it as fuel,we also cut down lots of them to make flat land so we can make communities.
We also use it to make paper and homes .Sometimes people illegally cut them down to make money and to steal.The most popular one is cattle ranching cattle ranching is where we cut down trees make land and keep cattles their so we can grow them, with fresh grass and when

‘If you could follow a molecule of water you would see that most of the clouds that are over São Paulo have passed across the Amazon’.‘If the forest is cut, we’ll be in trouble’’.Since the amazon is making Sao Paulo lose water in the future the drought of Sao Paulo will affect other countries/cities which will affect more and more.
If it affects so many places everyone will be doomed and we will have place to live. Seventy percent of the earth's land and animals live in rainforests most of it the Amazon. Most of our exotic animals we have today will soon be extinct if we cut down all of the Amazon and other rainforests.The Amazon alone is vanishing at a rate of 20,000 square miles a year imagine how much land that is.Mississauga itself is only 112.9 square miles so one year of deforestation of the amazon is 177.147918 times bigger than Mississauga itself.It is basically the size of contiguous United
Therefore, a large amount of trees were cut down and led to forest destruction. People have done these kinds of activities for many years and these deforestation activities have brought about a lot of permanent and long term issues. Although the society has started to consider the problem of deforestation, it is not easy to solve the issues completely. Land desertification can be a huge area and it almost cannot be controlled. In addition, it is not only threatening the people and animals in the Amazon, the world is also threatened by deforestation.
The Amazon Rain Forest Is in Danger of Being Destroyed" by Devadas Vittal. Rain Forests. HaiSong Harvey, Ed. At Issue Series. Greenhaven Press, 2002.

This practice is a quick and economically inexpensive method or clearing land for grazing or raising crops. It is accomplished by cutting down all the trees and brush in an area, as fast as possible (Slash) and then setting fire to the area, to get rid of all of the mess (Burn). It has proved to be a quite efficient way to pointlessly destroy the forest, because the land shortly becomes arid and barren without the trees there to maintain it's former richness. This is compounded by the lack of crop-rotation, which only speeds up the process of dry des...
Forests are basically a complex mix of living things such as animals, trees, shrubs, plants, fungi, and many more, as they cover about 40% of Canada’s land. As forests play an important role in this complex community, as we need those to survive to build shelter, food for animals, and most important is fresh air.
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.
Nevertheless there are still huge advantages of deforestation. But does this mean 2.47 acres of rainforest should be destroyed every single second? This mean every second of the day size of two football field is lost forever. Rainforests are the most productive and most complex ecosystems on Earth. Amazon rainforest alone produces 20% of the world’s oxygen.
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.
Precipitation is absorbed by vegetation and some of the water is used in the soil that would eventually help plants grow and evapotranspirated (Eves 40-42). This proves that deforestation increases total water runoff. Noah Webster noticed that forests try to maintain the probability of floods and droughts; when the land becomes deforested, that factor is removed (Eves, 42). When deforestation happens, it causes a more probable chance of erosion developing in the soil. At the beginning of the article, John A. Poor, railroad advocate, spoke about the transformation of the Kenduskeag stream by saying, “[W]ith its beautiful cascades from Six Mile Falls to tide water, has shrunk to a comparative rivulet in summer time by the clearing of the forest” (Eves, 38). Moreover, in the source “The Rate and Extent of Deforestation in Watersheds of the Southwestern Amazon Basin,” it explains how the rate of deforestation determines the effects on the terrestrial and aquatic ecosystems. (Biggs, et al., 31). The changes can either be “transient or chronic depending on the rate of clearing” (Biggs, et al.,
Rainforests once covered 14% of the worlds land surface, however now it only covers a mere 6%. It is estimated that all rainforests could be consumed in less than 40 years. Trees are becoming more needed and used everyday. We need them cut down for many reasons such as paper and timber, while also needing them ‘untouched’ for other reasons like oxygen, we have to ask ourselves, which is more important? At the current rate, most of the rainforests are being cut down for resources like paper and timber, but less importance is being placed on main resources like oxygen.
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.
Though deforestation has increased at an alarming rate throughout the past fifty years, deforestation has been performed during the course of history. According to the World Resources Institute, a majority of the world’s enduring naturally occurring forests are found in Alaska, Canada, Russia and the Northwestern Amazon. Research has demonstrated forests are more likely to be destroyed and repurposed where economic revenues tied to agriculture and pasture are prominent, typically attributed to advantageous weather conditions, or lower expenses of demolishing the forest and delivering merchandises to the global
to cut down trees in rainforests? Rainforests are meant to be beautiful, peaceful places where people can visit, but no, the trees. are cut down for wood and paper. Think of all the hundreds of species. who live in the rainforest, who are pushed out of their homes.
Timber and especially hardwoods like mahogany and ebony are being felled at an alarming rate to satisfy the needs of the swiftly developing world. Another problem for the forest areas of the world is the type of agriculture used by some peasant farmers known as "slash & burn". This method of farming involves the burning of trees to add to the initial supply of nutrients in the soil. Over time this supply slowly wares down and so the farmer once again moves onto another plot of trees to slash and burn.
The problem I have chosen is the problem of endangered species. An endangered species is a group of organisms that have a risk of becoming extinct. More than 90% of all species that have ever lived on earth has become extinct. Many reasons for this are habitat loss, predators, too few organisms for sustainable reproduction. Habitat loss is the most widespread cause of species endangerment and extinction. Usually, this is happening because of human activity including deforestation and pollution. Pollution and climate change affect the ecosystem, resulting in rise of sea levels, melting of glaciers/ice caps, and pollution can cause death to many seabirds and and marine creatures living on the coast and in the ocean. Rising sea levels can
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.
