Deforestation and forest burning by humans cause unnatural reversal in eastern Amazonia.
The Amazon rainforest in South America was one of Earth’s principal absorbers of carbon dioxide or carbon sink. However, a new study says that part of the rainforest is now emitting more carbon dioxide than it is soaking up, thus becoming a carbon source.
A team of researchers from different countries have said this area is on the eastern side of the Amazon, which covers around 20 percent of the rainforest basin, as per a study published in Nature Communications journal on July 14.
This land carbon sink in the largest tropical forests, called Amazonia, has been absorbing roughly a quarter of all fossil fuel emissions since 1960, researchers said.
