Of course, the Amazon Rainforest is the most significant of these, covering a vast portion of the country and providing the ideal habitat to approximately one-third of all animal species in the world. To date, there have been identified approximately 56 species of plants described1 bird species, amphibian species, mammal species and reptile species. However, when they are destroyed, the trees release the Carbon as greenhouse gases, with huge implications for earth and its atmosphere.

Therefore these factor less in overall deforestation figures. The above pie chart showing deforestation in the Amazon by cause is based on the median figures for estimate ranges. In a region where land prices are appreciating quickly, cattle ranching is used as a vehicle for land speculation, much of which is illegal.
Forestland has little value—but cleared pastureland can be used to produce cattle or sold to large-scale farmers, including soy planters. However the situation — at least in the Brazilian Amazon — may be starting to change.
Since major cattle buyers and the Brazilian government — pushed by environmental campaigners — have cracked down on deforestation for cattle production. State-run banks are now mandating landowners register their properties for environmental compliance in order to gain access to low-interest loans.
Such trends have yet to emerge in Peru, Bolivia, and Colombia, where cattle ranching remains a major driver of Amazon forest loss.
Colonization and subsequent subsistence agriculture Historically, subsistence agriculture has been an important cause of deforestation in the Amazon.
Small-scale agriculture has often been facilitated by government colonization programs aiming to alleviate urban population pressure by redistributing or granting rural land to the poor.
In some cases these programs have failed to meet their development goals while simultaneously unleashing an environmental Armageddon. The project was plagued from the start. The sediments of the Amazon Basin rendered the highway unstable and subject to inundation during heavy rains, blocking traffic and leaving crops to rot.
Harvest yields for poor farmers were dismal due to poor training and inadequate soils, which were quickly exhausted necessitating more forest clearing. Logging was difficult due to the low density of commercially exploitable trees. Many colonists, unfamiliar with banking and lured by easy credit, went deep into debt.
Adding to the debacle was the environmental cost of the project. After the construction of the Trans-Amazonian Highway, Brazilian deforestation accelerated to levels never before seen.
Small scale deforestation in the Colombian Amazon Commercial agriculture After the commercialization of a new variety of soybean developed by Brazilian scientists to flourish in rainforest climate, soy emerged as one of the most important contributors to deforestation in the Brazilian Amazon from the s through the mids.
Soy was both a direct and indirect deforestation. However deforestation for soy is still widespread in Bolivia and Paraguay. Meanwhile other forms of commercial agriculture, including rice, corn, and sugar cane, also contribute to deforestation in the Amazon, both directly through forest conversion and indirectly by driving up land values.
Soy in the Brazilian Amazon Logging In theory, logging in the Amazon is controlled by strict licensing which allows timber to be harvested only in designated areas, but in practice, illegal logging remains widespread in Brazil and Peru. Logging in the Amazon is closely linked with road building.
Studies by the Environmental Defense Fund show that areas that have been selectively logged are eight times more likely to be settled and cleared by shifting cultivators than untouched rainforests because of access granted by logging roads.
Logging roads give colonists access to remote rainforest areas.
Logging in the Amazon Other causes of forest loss in the Amazon Historically, hydroelectric projects have flooded vast areas of Amazon rainforest.
The Balbina dam flooded some 2, square kilometers square miles of rainforest when it was completed. Today dams drive deforestation by powering industrial mining and farming projects. Hundreds of dams are planned in the Amazon basin over the next 20 years.
Mining has had a substantial impact in the Amazon. High mineral and precious metal prices has spurred unprecedented invasions of rainforest lands across Brazil, Venezuela, Colombia, French Guiana, Suriname, Guyana, and Peru.
A study found that the area torn up for small-scale gold mining increased percent in 13 years. Oil and gas development is fueling environmental concerns in the Western Amazon.
Large blocks of rainforest have been granted for exploration and exploitation licenses in recent years.Brazil is the world's second largest producer of ethanol ph-vs.com and the United States led the industrial production of ethanol fuel in , together accounting for percent of the world's production.
In Brazil produced billion liters ( billion U.S. liquid gallons), representing percent of the world's total ethanol used as fuel. Regardless of the cause, cutting down rain forests reduces the number of trees available to take carbon dioxide and produce oxygen. Additionally, large scale deforestation by companies limits the local population's ability to farm, which in turn harms their economy.

On the one hand, the achievements of science, technique and industry point the way forward to a dazzling future of prosperity, social well-being and unlimited cultural advance.
Director’s Note: The science and research done on the true impacts of animal agriculture is always growing. The statistics used in the film were based on the best information we had available while producing the film. After the commercialization of a new variety of soybean developed by Brazilian scientists to flourish in rainforest climate, soy emerged as one of the most important contributors to deforestation in the Brazilian Amazon from the s through the mids.
Cutting down the Brazilian rainforest is not a morally just thing to do. Not only does leave the soil sterile and cut the land used for crops' life in half, but it also eliminates the opportunity for new medicines to be found, new plants to use for treatment in the medical field, and petroleum substitutes to be collected and used, just to name a few.4/4(1).
