Transcript of Amazon Deforestation: a Popular Problem

Deforestation: a Popular Problem Most Interesting Evidence: Why the Amazon is so important It's huge Although rainforest deforestation in the Amazon has been a widely popular
problem for years, it continues to have economical, environmental, and social problems on both a local and global scale, and it is imperative for our world’s survival that it stops. Deforestation is the destruction of most or all of the trees in a forested area. It can erode soils, contribute to pollution of waterways, and decrease biodiversity through the destruction of habitat. The Enemy = Agriculture "By 2006, an estimated 17% of Brazil's original Amazon rainforest cover had been destroyed, an area larger than France."-- Alana Herro In other words, the size of Texas. Method most commonly used for deforestation Burning the forest No nutrients in the soil The grass for the cattle can't grow “Amazonia—South America’s heartland—covers 2.5 million square miles in parts of Brazil, Bolivia, Columbia, Ecuador, French Guina, Guyana, Peru, Suriname, and Venezuela” (Miller & Tangley 53) Not only is the Amazon River bigger than any other river, but it is also bigger than the next EIGHT rivers put together. “Marajo, an island in the Amazon estuary, is the size of Switzerland. At the river’s mouth its north and south banks are farther apart than are Paris and London”
--Miller & Tangley 53 The Naysayers Say: 40% of the population of developing nations-- about 1.2 billlion people-- live in absolute grinding poverty" (Miller & Tangley 50). The poor economy of the Amazonian countries causes deforestation to continue. therefore Supporters of deforestation say that deforestation helps the economy of the poor countries of South America. however Deforestation is not actually economically beneficial. "Despite gaining some temporary benefits, communities that clear-cut their forests end up no better off than those who do not." --Eliza Strickland Most Important Thing I Learned: So What? The forest needs to be saved. "If one-fourth of all species vanished by 2050 or so, as some scientists predict, and if we assume (very conservatively) that Earth houses 10 million species, 15,000 to 50,000 species are dying out each year in the tropics." --Miller & Tangley 20 Our planet can only take so much abuse. The time for it to stop is now My Sources The 3 most important sources I used were: 1. David Collins' The Last Rain Forests This was an important source because it provided me with many interesting facts about the Amazon rainforest in general 2. Kenton Miller and Laura Tangley's Trees of Life: Saving Tropical Rainforests and Their Biological Wealth This was an important source because it highlighted the Amazon rainforest and ways that governments can help to conserve it. 3. Nick Hanley and Colin Robert's Issues in Environmental Economics This was an important source because it focuses on the economics of tropical deforestation What did I learn about the writing process? I learned a lot about the process of revision. Especially when it comes to the main claim. Writing a draft of the main claim before compleating much of the research was interesting for me. It certainly came a long way from where it started. Supporting Argument The need to burn down even more forest for grazing land The End The broadening of a river where the river and sea meet
