The Amazon rain forest has many things to show for. The Amazon river is the largest river in the world.A total of about two thousand species of fish have been found here. That is more than the whole Atlantic Ocean.If the Amazon was a country it wold be the ninth largest in the world. It has one of the most valuable natural resources in the world. Fruits and vegetables are also found in the rain forest. Some biochemists think that alkaloids protect plants from disease. Many professionals believe that by leaving the rain forest as is, and harvesting the land would make it go up to a high cost. There are also about a hundred and twenty prescription drugs sold worldwide come from plants in the rain forest. The US Cancer institute has found three thousand plants that help to fight against these cancer cells. About seventy percent of these come from the rain forest. Also about a fourth of cancer ingredients come from organisms that are in the rain forest. Also a plant called periwinkle has an ingredient, called vincristine that helps the survival rate for cancer patients. Also there are people found in the rain forest. ‘’The tallest of these people known as the Mbuti, rarely exceed five feet tall. Their bodies have adapted the shorter they are. The less heat that gets to them. ‘’These people live in groups that range from fifteen to fifty people.’’ The people of the forest are nomads and move three to four times a year. ‘’Most of the people that live in the forest, have a better survival rate, they have less chance of disease, and they have better water to drink. ‘’ When they arrive into another settlement they chop down big trees, and leave the remaining ones left standing. ‘’They then build their house. The rain forest wood is very v... ... middle of paper ... ...fifteen hundred other plants.’’ ‘’The Andean Mountain Range and the Amazon jungle are home to more than half the population has increased by about thirty percent. By the year of two thousand and twenty demands for rice, corn, wheat, and other farming produce will increase. That would make water demands at fifty percent higher. The people called Shaman; scientists believe that for each man dies a thousand years of medicine dies with them. ‘’Scientists are trying to learn these medicines, but it is hard to get them to talk, but it’s hard to get them to talk.’’ Their people are dying, and only a few thousand Shamans remain. The medical discoveries of the rain forest inferences are being constantly updated with new information, to help endangered animals and to get cancer items from the rain forest. If the rain forest vanishes we’ll be back to the stone age.

The dense levels of vegetation absorb tremendous amounts of carbon dioxide in the atmosphere and help slow down the rate of climate change that the planet is experiencing. This process also produces high levels of oxygen that help to support life around the world. Coupled with the high levels of rainfall that benefit the water cycle, the rainforests are an integral part of the many systems that exist. These forests contain a wide variety of plants that a source of different chemicals that are used to create medicines. The degradation of these areas could potentially lead to the loss of medicines that could cure some of the deadliest diseases and illnesses that
The Amazon Rain Forest Is in Danger of Being Destroyed" by Devadas Vittal. Rain Forests. HaiSong Harvey, Ed. At Issue Series. Greenhaven Press, 2002.

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...
No matter where a person lives, even if it is not near a rain forest, the complete destruction of rain forests will affect living conditions. For years rain forests have provided countries around the word with valuable resources, minerals, lumber, and energy. In Brazil alone the rain forests contains 45% of Brazil’s hydroelectric power. The minerals found in the rain forests of Brazil are estimated to value 1.6 trillion dollars, while the lumber that the rain forests can provide total 1.7 trillion dollars (“In the Forest” 1). Nutrients from decomposing organisms can be found throughout rain forests, including in soil and in trees. To continue destroying forests also destroys the important materials that they are providing to humans.
The Amazon Rainforest or know to many as the “Amazon Jungle” sits on about 2.124 million miles2 and is home to about 10 million species of animals and over 40,000 different plant species. Not including over 2.5 million different insect species. The amazon rainforest is the largest rainforest on earth. The Amazon rainforest is located in South America , it covers much of northwest Brazil and extends into Colombia,Peru and other countries. Part of the Amazon Rainforest is the River that flows through South America and is a big part of the Amazon Rainforest. The Amazon is the seventh oldest rainforest in the world and has existed for about 55 years.
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.
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.
First of all I would have to say that yes it has a great impact on our global warming and I will go on to explain to you how it affects our planet. We as a whole have let the dollar get in the way of how our planet is affected, some would say at all costs. It is true we have refineries, car pollution, but most of all deforestation of tropical areas. In the National Geographic Magazine you will come to see and appreciate the facts of how deforestation has affected our nation and has spiraled into global warming. We can look at Brazil’s rainforest that is estimated to be larger than two hundred football fields it will be destroyed before you are even able to read the article at hand (Magazine, 1996-2014). It has been noted that within the past 40 years we have managed to do more damage than what was done in the four hundred and fifty (450) years since the European Colonization even began. That sent chills through my bones when I read that, imagine how much tropical areas have been affected. We have destroyed twen...
Deforestation of the Amazon River basin has been progressing for decades as mass quantities of land have become necessary to sustain the growing farming industry of the area. Road-building, farming, ranching, and logging have been devastating to the tropical forests and the change has been rapid as deforestation of the area only began around 1970 (Fearnside, Pfaff). The government of countries in the Amazon have designed their current initiatives around increasing infrastructure and business, but these initiatives are largely responsible for deforestation activity (Laurance). The decline in forests of this region has become a serious issue as the effects it has on the climate and ecosystem of the Amazon River basin and the rest of the world are great. The high rate of deforestation in this area, averaging from 25,000 to 50,000 square kilometers per year since 1970, suggests numbers that project a complete absence of Amazonian tropical forest within the next 50 to 100 years if greater prevention methods are not taken (Shukla). These number projections mean threatening futures for deforestation dynamics, carbon fluxes, forest fragmentation, impacted ecosystems, social issues, and climates both of the region and the world.

The forests around the world a supply a plethora of community amenities and commercial goods , nevertheless forested terrain progressively is becoming transformed to accommodate other uses, including cropland, pasture, mining, and urban areas, which can produce superior private financial returns. The wide array of benefits the forest provides that vanish directly tied to deforestation have resulted in several policies drafted with the sole intention to reduce the frequency of deforestation. This paper has two primary objectives. First, this paper will review and summarize both the preceding and current research on deforestation. Second, it will emphasize the significance of future research and development, as well as other solutions needed
Throughout the ages, the earth and its inhabitants have undergone a variety of changes that have had a major effect on the earth’s vegetation and animals. The most prominent of these changes is climate change, or global warming. According to Merriam-Webster, global warming is, “an increase in the earth 's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution”. This increase in atmospheric and oceanic temperatures has led to several geographic and evolutionary changes. For example, it has caused glaciers to melt and sea levels to rise. However, one of the most significant of these effects is the effect that climate change has had on rainforests. From South
During the past several decades, changes in the global climatic pattern has become evident and has attracted much attention from both the general public and the professional environmental organizations. Deforestation is one of the main reasons for these known changes. One of the reasons that cause the disappearing of the Amazon rainforest is industrial logging, which is the single largest problem. Other problems that also contribute to the disappearing of the Amazon forests include road construction, cattle ranching, and the production of wood products, all of which are important factors to be considered. The Amazon rainforest is the world's largest rain forest today, which has 54 percent of the total rainforests that are remaining on the planet. If Amazonia is a country, it would be the ninth largest country in the world. The Amazon is very important because it is a major contributor to the balance of global climatic patterns and because it provides places for variety of living organisms. A single pond in Brazil can contain more kinds of fish than are found in all of Europe's rivers. Twenty-five acre of rainforest in Borneo may contain over seven hundred species of trees, which is equal to the number of trees in the whole North America; one single rainforest in Peru has more bird species than the entire United States. One tree in Peru had forty-three different species of ants, which is the estimated to be equal to the number of ant species in the British Isles. The Amazon rainforest is truly amazing.

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.
