Brazil has many great things to offer the world like a booming economy and beautiful culture; however, a problem that is prevalent in this large country is the clearing of the trees in the Amazon Forest. Ever since the beginning of mankind, people have looked to forests to gather resources for survival. As technology became more advanced, people learned methods that would help them clear trees faster and with less effort, and this would soon become a controversial topic as the world moved into the twentieth century. This is an issue because there are two opposing sides in this situation. One side agrees with obtaining mass amounts of trees in exchange for high quantities of fuel and food that are vital for human survival and urban development, …show more content…
Advocates for the stopping of deforestation in Brazil are not concerned with how much money is being made; instead, they are worried about the depletion of resources that will affect future human generations as well as the destruction of homes that once belonged to the animals of the rainforest. Habitat loss is said to be the highest threat to endangered species because it limits biodiversity. Having an assortment of plants and animals in the Amazonian region is crucial because genetic diversity aids people in studying wildlife anatomy and creating medicines. If deforestation were to stop, animals that use the rainforest as their only habitat will be able to thrive and live normal, healthy lives. While the land is urbanizing due to the increase of business in the area, roads must be built to transport goods and people, and this can lead to habitat fragmentation. Dividing a species’ ecosystem is harmful because it confines their movement. This restriction placed on the animals can also cause the loss of biodiversity among the plants and animals in the Amazon, and Barbara Fraser proposes that “research is now showing that the building of roads also triggers a cascade of environmental changes in the remaining forest that can dry out trees, set the stage for wildfires and weaken the ecosystem” (1). Roads have had a tremendous impact on the dwindling number of trees in the area, and it has shown to have delayed effects on the environment in addition to the immediate consequences aimed at the animals. An atmospheric scientist visited a soybean farm that was once a lush forest to find that “The air [was] noticeably hotter and drier in the field than in one of the few patches of forest left on the farm” (1) . Trees provide so much moisture to the atmosphere through the process of evapotranspiration, so the water in the atmosphere will disappear

The efforts required by reforestation may not initially be cost effective, but it will result in not only the survivability of the environment, but of the country’s economy. Widespread awareness of these ideas will help fight against the natural human tendency towards instant gratification and short-term goals. Different methods of logging can be utilized to allow the rainforests to survive and regrow naturally and at a sustainable

In “Battle for the Amazon,” Jeff Tollefson highlights the numerous regulations implemented by the Brazilian government to decrease deforestation and details the role of U.S. companies in the fight against land clearing in the Amazon basin. Tollefson states that major U.S. companies “could be held accountable for marketing illegal products” that have been extracted from deforested land (21).
The introduction of cattle ranching industries in the 1960s set the forefront for current Brazilian rainforest deforestation figures. During this time, development subsidy programs encouraged Brazilians to clear rainforest for pastureland and invest in new cattle ranches (Pancheco). Over the last 40 years, Brazil has destroyed 700,00 square kilometers of rainforest, an area about the size of Texas (BBC) (Enchanted Lear...
Cho 1 Deforestation of the Amazon Rainforest: The Amazon is the world’s largest tropical rainforest and home to millions of species (National science foundation, 2011). Deforestation has increased rapidly over the last 5 years. Did you know that one hundred fifty billion meters of forest are lost each year? That is equivalent to about 36 football fields per minute!
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 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 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.
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...
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 planets 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. At its current state, the Amazon is losing land equal to the size of the state of Delaware every year. The destruction of this forest releases 340 million tons of carbon per year according to the World Wildlife Foundation, or WWF, which in turn cause climate changes everywhere around the world. Undiscovered species can hold the key to curing a plethora of diseases, but if those species become extinct those keys are lost forever. If nothing is done to prevent this, the world’s treasure trove of bio-diversity will cease to exist, creating irreversible damage to not only the South American people but also the rest of the world.
