Close The Amazon rainforest: Our goal is to prevent this catastrophe.
Why the Amazon is important Page last updated: There are three fundamental reasons why the region is important to the rest of the world.
The Amazon and the world's climate It is not surprising that the Amazon region is often called the "lungs of the world," as it plays a critical role in the global carbon cycle that helps to shape the world's climate. About billion tonnes of carbon are locked up in tropical vegetation around the world, of which about 70 billion tonnes are estimated to be in Amazon trees.
Rapid rates of deforestation cause more carbon to be converted into carbon dioxide, either when the trees are burnt down or more slowly by the decomposition of unburned wood. And once the forests are gone, they cannot soak up the carbon from cars, power plants and factories.
At the moment the Amazon is thought to absorb about 10 per cent of global fossil fuel carbon dioxide emissions. Burning is leading to a vicious circle of carbon release The build-up of carbon dioxide in the earth's atmosphere is one of the key causes of global warming.
About 20 per cent of annual global greenhouse emissions is estimated to come from the clearing of tropical forests around the world. According to the Stern Report on the economics of climate change, the loss of natural forests around the world contributes more to global emissions each year than the transport sector.
Brazil, for example, is ranked in the top five of the world's largest emitters of greenhouse gases, not because of its high emissions from fossil fuels but because of deforestation. Tipping Point A study released in February by a team of international scientists from Oxford University, the Potsdam Institute and others concluded that the Amazon rainforest was the second most vulnerable area in the world after the Arctic.
Scientists and climate change modellers disagree how soon a tipping point might happen or how likely it is. But however low the probability, changes to the Amazon are likely to be a "high impact" event on the world's climate. Biodiversity The Amazon is the world's largest tract of tropical rainforest, containing the Earth's greatest biological reservoir - around 30 percent of all terrestrial species are found there.
The region is the main reason why Brazil is the most bio-diverse country in the world, with more than 50, described species of plants, 1, species of birds and between and different types each of amphibians, mammals and reptiles.
All this rich biodiversity is now being threatened by the destructive combination of stress from climate change and deforestation. Even though there are many unknowns about the Amazon's future and its effect on the world's climate, scientists agree that because of its biodiversity and the crucial role the region plays in shaping the climate, it is a matter of great urgency to find the right policy mix to conserve enough of the forest.Amazon Rainforest is the largest forest of earth which represents over 60 percent of the world's remaining rainforests.
The Amazon is the most biodiverse terrestrial place on the planet. This amazing rainforest is home to more species of birds, plants and mammals. The Amazon is the most biodiverse terrestrial place on the planet. This amazing rainforest is home to more species of birds, plants and mammals than anywhere else in the world.
Around 30% of the world’s species, and 10% of the world’s biodiversity, can be found there. Why Is The Amazon So Important? With the Amazon River flowing an impressive 6,km, and containing hundreds of tributaries and smaller streams, it’s no wonder that it’s home to the largest number of freshwater fish species in the world.
The outstanding biodiversity in the Amazon isn’t only important for the natural ecosystems, it. Amazon Rainforest Importance February 27, For the indigenous population the Amazon rainforest is important because it is their home and their culture is closely related to the forest, rivers and fauna.
Within the Amazon Basin, tens of millions of people depend on services afforded by the forest. Rivers are the main vectors for transportation, while logging and collection of non-timber forest products are major industries in many cities, towns, and villages.
The Amazon River basin (ca. 6 million km2) is the largest in the world with mean discharge measured in the Amazon River at the outlet of ca.
