The Effect of Deforestation in the Amazon Rainforest on Golden Lion Tamarins Deforestation is the permanent removal of forests to make room for other uses of the land (McIntyre). The Amazon rainforest stretches for 1.6 million square miles, holds 1/10 of the world’s species and provides natural assets for both regional and national economies (“Deforestation of the Amazon Rainforest”). Despite its great importance to the Earth, the Amazon rainforest is perhaps the most threatened area of deforestation around the world. Timothy Casey reports that in Brazil alone, 5.4 million acres of rainforest have been destroyed for the past 30 years, decreasing the size of the Amazon by eighteen percent (13). A main aspect of this issue is that it destroys habitats for important species, causing extinction and endangerment.
The loss of forests means the loss of habitats for many species. Current statistics show that as many as 100 species become extinct every day with a large portion being attributed to deforestation (Delfgaauw, 1996). "Edge effects" are the destruction or degradation of natural habitat that occur on the fringes of fragmented forests. The effects for the animals include greater exposure to the elements (wind, rain etc…), other non-forest animals and humans (Dunbar, 1993). This unnatural extinction of species endangers the world's food supply, threatens many human resources and has profound implications for biological diversity.
With twenty percent of it already destroyed, oxygen in the atmosphere has decreased significantly. Every year an area larger than the state of Maryland will be destroyed along with the ecological humans, plants, and animals that reside there. The Amazon Rainforest is home to approximately 400 native tribes and is the ancestral home of over 1 million tribal people. These indigenous people have disappeared due to the injustice groups that have been cutting down the trees and taking the land that the native tribes have been calling their home for the past several centuries. That soon changed when the private companies and the black market of Brazil started targeting the Amazon Rainforest for its rich, fertile land.
According to the article satellite images reflect that the Amazon rainforest is diminishing at an enormous rate. About 10,000 square miles of this beautiful forest is being lost to pastures for grazing, soybean plantations, and illegal logging. Since the year before there has been a forty percent increase in the deforestation of the Amazon forest. The Amazon is the world’s largest tropical rainforest. They expect this horrible trend to only become worse.
Habitat loss is the most widespread cause of species endangerment and extinction. Usually, this is happening because of human activity including deforestation and pollution. Pollution and climate change affect the ecosystem, resulting in rise of sea levels, melting of glaciers/ice caps, and pollution can cause death to many seabirds and and marine creatures living on the coast and in the ocean. Rising sea levels can
Harvard University biologist E.O. Wilson estimates "that 50,000 plant and animal species disappear each year due to tropical deforestation, expanding agriculture, and human settlement." (Hinrichsen, 1999) Human activities impact the environment, including clearing agricultural land; air, land and water pollution; urban and suburban development; and the introduction of invasive or non-native wildlife species. If land and wildlife are poorly managed, humans risk fragmenting habitat, destroying essential wilderness, and altering food webs and species relationships. As the birth of the sixth billionth person on earth has come and gone environmental consideration has never been a more important issue.
Other countries be saying that brazil is responsible for the deforestation in the amazon, deforestation has declined significantly since 2004, thanks to the creation of national parks and enforcement of laws. During the past 40 years, close to 20 percent of the Amazon rainforest has been cut down. An area of Brazil 's rain forest larger than 200 football fields will have been destroyed. The market forces of globalization are invading the Amazon. In the past 3 decades, hundreds of people have died in land wars; countless others endure fear and uncertainty, their lives threatened by those who profit from the theft of timber and land.
Approximately 9 million types of plants, animals, protists and fungi inhabit the Earth. So, too, do 7 billion people. Two decades ago, at the first Earth Summit, the vast majority of the world’s nations declared that human actions were dismantling the Earth’s ecosystems, eliminating genes, species and biological traits at an alarming rate. This observation led to the question of how such loss of biological diversity will alter the functioning of ecosystems and their ability to provide society with the goods and services needed to prosper. Till now estimated about 75% of genetic diversity of agricultural crops has been lost.
Humans have already destroyed half of this forest area, with most damage occurring in the last 200 years (Bagheera, 1996). In 1987 alone an estimated 20 million acres of Brazilian rainforest were cut and burned (Miller & Tangley, 1991, in Kricher, 1997). At the current rate of deforestation, within 177 years all tropical rainforests on Earth could be gone (Kricher, 1997). The effects of this massive deforestation have already begun to influence the planet. Among the many threats of tropical deforestation, global warming is perhaps one of the most severe.
Most of the Amazon is still pristine, but the region is being destroyed at an alarming rate. Over 8 million acres of the rainforest are lost every year. Between 1978 to 1996, 12.5 percent of the irreplacable rainforest was destroyed. Eighty-five percent of the trees that are being cut down are old growth. Old growth forests are forests that provide a crucial habitat for wildlife, cleanse toxins out of the air and water, are the home to the cultural heritage of many indigenous groups and are the source of many useful plants.
