The Amazon Rainforest is located south from the Equator. It passes through nine different countries, but 60% is located on Brazil. The Amazon River is 4000 miles long; this is about the same distance that separates New York from Berlin. The size of the Amazon Rainforest is 2.3 million square miles this is equivalent area to 2/3 of the U.S. The largest reservoir of fresh water is on the Amazon. 1/5 of all flowing water from the planet is located here, as well as the largest biodiversity hotspot. The National Academy of Sciences states that in a four square mile there are 150 species of butterflies, 400 of birds, 100 of reptiles and 125 of mammals. Examples of species are the capybara, Jesus lizard which can walk on water, the kinkajou, poison dart frog, and the bullet ant. Also it has many different types of flora, on 2.5 acres there are 700 different species of trees a 1400 of plants.
The Amazon is very important for the planet because it filters air. The Amazon rain forest is also known as the earth’s lungs, because its trees absorb carbon dioxide which is needed for photosynthesis, then releases oxygen and carbon that allows plants to grow. According to Scientific American the Amazon rainforest absorbs 1.5 billion metric tons of carbon dioxide per year. If forests are deforested more carbon dioxide will be in the atmosphere. Carbon dioxide is one of the main gases that produce global warming. The Amazon rainforest influences climates. Rainforests are very important to the water cycle, because they add water to the atmosphere when they are on the transpiration stage of photosynthesis. This transpiration forms rainy clouds. If deforestation increases there will be less moisture which will lead to a severe drought. One exampl...

...ction. Lots of indians die because of the Amazon getting destroyed. The climate is changing because of so much of the disappearing of the rainforest. In every 40 years 20 percent of the Amazon is completely gone. Sadly in about 30 - 40 years we will not have a Amazon rainforest. People are clearing out the Amazon because they want to grow plants and food but we used to have a lot of food but because of the Amazon getting destroying the we don’t have as much, and people want to clear out land for plants and foods but because of destruction the soil will dry out and we will have no more exzotic fruits. As you can see the Amazons environmental problems are devastating.
Tropical rainforests are an extremely unique and diverse ecosystem that are located around the earth’s equator. They once covered roughly 7% of the world, but due to human encroachment that has dwindled to just 2%. It is a highly moisture rich environment that typically receives anywhere between 60 and 400 inches of rainfall annually and average humidity ranges from 70 to 90%. A high average year round temperature, coupled with the moisture rich environment, creates an ecosystem that allows for a level of biodiversity seen nowhere else on the planet. This also results in a specific type of layering design that allows the system to survive and recycle its nutrients.
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 .
There are many rainforests in the world but one of the biggest one is the Amazon rainforest, which is located in the northern half of South America and lies in the countries of Brazil, Colombia, Peru, Venezuela, Ecuador, and Bolivia. The Amazon also lies in between the Tropic of Capricorn and the Tropic of Cancer. The size of the Amazon resembles the size of the United States from the Atlantic Ocean to the Rocky Mountains. Since this rain forest lies next to the Equator, the climate is warm and humid. The average temperature is in between sixty-eight to ninety- three degrees. The Amazon has two seasons but each one is six months each. They are classified as the wet season and the dry season. The wet season occurs between December to May and the dry season occurs between June to November. The average rainfall is fifty to two hundred and sixty inches per year. The forest floor only gets up to two to five percent of sunlight since the canopy blocks the sunlight from getting to the forest floor. The Amazon rain forest got the nickname, the world’s pharmacy, because many medicines have been found in the tree bark, the tree’s leaves, and other parts of the trees.
Thus, deforestation is one of the biggest problems in the world that people have to consider because it has three main long term effects: land desertification, species extinction and climate change. The research paper will discuss and consider the long-term negative effect on the Amazon rainforest which is caused by deforestation. First, the paper will present the causes and effects of land deforestation. Another consideration is endangered species extinction that could affect the Amazon’s biodiversity. Finally, the paper will focus on how climate change and global warming affect the Amazon and what people should do in order to save the forests and solve those problems.
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.
Deforestation is fast becoming one of the world’s worst environmental/geographical occurring disasters known to mankind, and is due to humankind’s greed, ignorance and carelessness when considering the future of our environment.
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.
Amazon: This is one of the most famous tropical rainforest in the world. Currently, it is the largest tropical rainforest in the world. The forest covers the basin of amazon, the world’s second longest river. The Amazon is home to many animals and even some of the plants greats. This rainforest has a great variety of plants and animals. 1/5 of the world’s plants and 1/10 of all mammal species are found there.
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...
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 also has an impact on the climate. “15% of all greenhouse gas emissions are the result of deforestation” (WWL). This is harmful to the climate as this leaves more carbon dioxide in the air. “Almost 200 tons of carbon dioxide can readily be stored on just on acre in a rain forest” (eHow). Imagine how much carbon dioxide we could rid the air of just by saving an acre of trees. Without the forests to protect soil and redistribute water in the air, the lavish forests can easily become barren deserts as time passes by.
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.
Simply speaking, rainforests are basically the foundation of the earth. The most important role that rainforests play is ‘the lungs of the earth’. This is extremely vital to the earth’s survival as the trees and plants absorb carbon dioxide which they use to help grow and let out oxygen which we need to live. This system is known as the carbon-oxygen cycle and with numbers of rainforests declining, it is highly threatened. The largest rainforest in the world, the Amazon, alone is known to produce half of the world’s oxygen. A break down in the carbon-oxygen cycle means that we will not only have less oxygen, but an increase in carbon dioxide which eventually leads to global warming. This occurs as carbon dioxide traps heat which actually keeps the earth warm, with the right amount of carbon dioxide that is. This is called the greenhouse effect and occurs naturally however due to decreasing number of trees, there is more carbon dioxide than needed which traps extra heat making the earth hotter than needed, this is known as global warming which also causes a rise in sea level.
The Amazon Rainforest is the world's largest tropical rainforest that we have today on our planet. It covers a wide range expanding almost entirely across from East to West of South America. It is most famous for its broad biodiversity and includes the famous Amazon River that is home to rare and diverse species. Today, the Amazon Rainforest is under threat of complete deforestation and has greatly lost more than half of its tropical rainforest due to cattle ranching, soy bean farming, sugar cane plantations, palm oil and biofuel agriculture. The indigenous people are doing their best to fight against the government to protect their land and conserve the rainforest but without capital finance, it is seeming to be an impossible project.
