Half of the world's wetlands were lost last century.
Home Rainforest Primer 4. The Neotropics 2 Brazil 2 Brazil Brazil is an object lesson in forest destruction. One nearly extinct rainforest is the Atlantic forest of Brazil, which originally had an area of one million km2, but by now, consists of only 35, km2.
Much of it has been cut for farms and ranches, and the government at one time offered tax breaks for raising Asian water buffalo still a favored project in Amazonia. The Atlantic forest is the only home of the highly endangered golden tamarin, among many other threatened species.
The forest now consists largely of remnant patches in a sea of agricultural fields. There are some protected areas, but they are small the largest are hectares in sizevirtually unprotected, and subject to great hunting pressures.
Many birds, such as guans, chachalacas, toucans and aracaris, which are dispersers of Deforestation case study brazil seeds, are near extinction, and the Alagoas curassow is extinct in the wild because of hunting.
Most large vertebrates have also disappeared due to habitat fragmentation and hunting. The loss of these seed-dispersing animals will lead to alterations in the composition of the remaining forest, because the tree species those with large seeds; about one-third of tree species in the Atlantic forest dependent upon seed-dispersers will not be able to reproduce.
The Brazilian Amazon consists of more than five million km2, of which slightly more than four million km2 are forested. Prior to only about 30, km2 0. By, km2 had been cleared, by, km2, an area the size of France Moran, Skole and Tucker give a figure ofkm2 of deforestation, or 5.
Deforestation continues at a rate of 15, to 20, km2 annually.
These figures are only estimates, as mapping forest loss accurately is very difficult. During the first twenty years after road construction, twenty million people settled along the road. Large areas near the roads were cleared for cattle pasture, and the cattle population went from zero to five million Moran, ; Dobson, The governor of one state announced plans to shoot, catch and sell all the wild animals in the forest, exploit the plants in the forest, and then convert it all to agricultural land Jacobs, !
In Rondonia state, where government policies and road construction activities have encouraged immigration, more than a quarter of the land was deforested between andand the process has only accelerated since.
The average area deforested in Rondonia per year equals the total area deforested prior to Moran, Among the ancillary consequences of deforestation is a loss of the immense biodiversity of the Brazilian Amazon.
Mammals are declining everywhere from the impact of hunting for food, skins, and medicines and habitat loss. Jaguars are collected for zoos and illegally hunted for their skins.
They are also declining because of habitat loss, as each jaguar requires large areas for hunting. The giant anteater, the armadillo and others have been depleted by habitat loss, demands from zoos, and hunting.
Birds are being lost for similar reasons. Reptiles, especially tortoises, alligators, and freshwater turtles, are hunted for food and hides, in the case of the alligator. Populations of the arrau, a turtle found in the Amazon and Orinoco basins, are in great decline because of the consumption of eggs and adults by humans, and the terecay turtle is in similar dire straits.
Fish, the main protein source for humans in the Amazon, are intensely sought as the human population increases and fishing becomes more efficient and mechanized.
And the bushmeat trade is growing. Many species of mammals and reptiles can be found in markets and on restaurant menus. Animals and plants are also sought for pets and gardens. Fish are extracted from tropical forest rivers and streams for the aquarium trade, although most of them die en route to their foreign destinations.
Many animals are found for sale as pets in tropical town markets. Monkeys, for instance, are common in South American markets. Why is Brazil a leader in deforestation? Land policies and speculation: Ranchers do not utilize the timber on land as they deforest it, they burn it. Since uncleared land cannot be claimed in Brazil, deforestation proceeds indiscriminately in efforts to take land title.
In fact, one can receive six additional hectares of land for each hectare cleared, although the land is frequently used for a few years and subsequently abandoned.
The Belem-Brasilia, Cuiaba-Santarem and Trans-Amazon highways are huge arteries opening access to previously inaccessible parts of the country.
As roads are built, impoverished urban dwellers or landless farmers from other areas move in along them, deforesting small areas for agriculture. After they clear 50 hectares of land, they receive title to the land, which they cultivate or use to raise cattle.
After a few years, the soil is exhausted and they move on.Living World - Amazon Case Study The Amazon is the largest tropical rainforest on Earth.
It sits within the Amazon River basin, covers some 40% of the South American continent and as you can see on the map below includes parts of eight South American countries: Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, and Suriname. Brazil is the world's second largest producer of ethanol metin2sell.com and the United States led the industrial production of ethanol fuel in , together accounting for percent of the world's production.
