The Amazon Rainforest is environmentally harmed through development through means of extraction of its natural resources such as lumber, cattle ranching and agricultural practices. South America and particularly Brazil’s Amazon is environmentally exploited by multinational companies and the global north. With this the environmental consequences as well as the negative social, economic and political impacts should be considered. The sociopolitical variables relative to the aforementioned need to be evaluated. The Amazon Rainforest is a significant global environmental issue, as the impact on the natural environment is reflected from human activities. With this we consider development and environmental politics relative to the Amazon Rainforest. …show more content…
However it’s current state is impacted by significant extraction and use of it’s natural resources. Development and subsequent deforestation of the Amazon rainforest is a significant environmental topic of significance and needs consideration. The Forest has been depleted, “Since 1988, Brazilians have cleared more than 153,000 square miles of Amazonian rain forest, an area larger than Germany...Brazil has helped feed the growing global demand for commodities, such as soybeans and beef but the environmental price has been steep”(Tollefson). Practices such as cattle ranching and agriculture are primary development practices which are contributing to the continual deforestation of the Amazon Forest. The significance in understanding the environmental impacts on the Amazon Forest is imperative as the biodiversity and ecosystems are at risk as development continues. Moreover the continued extraction of the Amazon Forest’s resources is an ethical dilemma as future generations are at risk of being deprived from the quality of life their predecessors experienced. With this we analyze developmental practices in the region and consider policies surrounding the land use and extraction of Amazonian resources. Moreover it is important to evaluate the continued development of the Amazon Forest resources for economic gain, sustainability in question and at what cost can such practices …show more content…
With this Individuals perform local and regional survey’s as well as use empirical knowledge in order to estimate the vast number of species inhabiting the Amazon ranging from 3 million to 100 million species. With the uncertainty of just how many species are accounted for and the impacts made upon the ecosystem, some ecologists differ with respect to the harmful impacts of biodiversity. Some of the assumptions made regarding this uncertainty include estimates of potential future extinctions as mere estimated guesses, as well as an impracticality to apply an ‘island extinction model’ to a vastly large ecosystem such as that of the Amazon. This school of thought suggests that species loss is proportional to its given surrounding area. Islands provide a greater hostile environment, as they are surrounded by water and therefore certain needs are limited. In contrast, the Amazon forest provides a large ecosystem and variety of resources, therefore mass species extinction is not a legitimate threat. Despite this conflicting perspective the fact remains that the Amazon forest is continuing to be developed, with natural resources extracted and the ecosystems disruption at an exponentially increasing rate, the risk of species diminished resources may result in displacement or

This policy memo addresses the development and expansion of the cattle ranching industry in Brazil, which has contributed to the mass deforestation of the Brazilian Amazon in the last 40 years. It exposes the regional and global consequences to deforestation and provides strategies for the Brazilian government to sustainably manage cattle ranching industries while protecting the future of the Amazon. The rainforest ecosystem is an immense reserve of natural recourses that is far more valuable than the beef produced on Brazilian cattle ranches. Not only does the rainforest create habitat for up to 65% of the world’s biodiversity, but when harvested sustainably, it provides humans with an abundance of spices, foods, oils, medicines and vital research areas (NEWMAN).
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.
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.
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.

The Brazilian Rainforest is one of the most unique, vast, and diverse regions of the world. To get a general idea of the diversity of the Rainforest, it makes up a total of one-third of the world forests (more than four million square kilometers), it contains half of the total number of named species in the world (eighty-thousand plant species, 1,500 fish species, and one-forth of the 8,600 bird species), and is the world largest holder of genes (Library 138-139). To say the least, the Brazilian Rainforest is one of the most important natural resources we, as humans, know. It would seem that this knowledge, alone, would also make the Brazilian Rainforest one of the most protected land areas on Earth as well. However, the situation is quite the opposite. The Brazilian Rainforest has been greatly degraded by deforestation since the 1960 , which has led to numerous negative effects both environmentally and socially. This paper introduces the events that opened the door to deforestation, the most immediate causes and effects of deforestation in the Brazilian Rainforest, and my two-part solution to the problem of deforestation.
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...
The negative impact on the environment of the planned human expansion is tremendous. It has been estimated that 10 million hectares of the Amazon forest have been destroyed due to clear-cutting, burning, slash-and-burn agriculture and conversion to pastures. Deforestation is caused mainly by road construction since 74% of the converted areas is within 50 km of roads.1 This clearly shows that frontier expansion and colonization for economical and social reasons has a devastating effect on the environment. The Brazilian Amazon is the largest piece of undisturbed rain forest and, unfortunately, this natural treasure is being damaged very carelessly and at an extremely high rate.
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.
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.
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.
The Amazon rainforest has many problems. I will be telling you about three of them. they are that Sao Paulo is running out of water as the rain-making Amazon vanishes, the campaign to keep the oil in the ground in the Amazon, and lastly, about how Amazon Watch is standing with the Indigenous People, and defending the Rainforest...
