Deforestation of the Amazon rainforest though the annual rate of forest loss has generally been slowing since 2004. However, rates of deforestation jumped again in 2008, 2013 and 2015. In Brazil, the Instituto Nacional de Pesquisas Espaciais (INPE, or National Institute of Space Research) produces deforestation figures annually. Their deforestation estimates are derived from 100 to 220 images taken during the dry season in the Amazon by the Landsat satellite, also may only consider the loss of the Amazon rainforest – not the loss of natural fields or savannah within the Amazon biome. The native tribes of the Amazon have often been abused during the
Amazon rainforest has declined significantly in the Brazilian Amazon between 2004 and 2014, there has been an increase to the present day. Environmentalists are concerned about loss of biodiversity that will result from destruction of the forest, and also about the release of the carbon contained within the vegetation, which could accelerate global warming. Amazonian evergreen forests account for about 10% of the world's terrestrial primary productivity and 10% of the carbon stores in ecosystems – of the order of 1.1 × 10 metric tonnes of carbon. Amazonian forests are estimated to have accumulated 0.62 ± 0.37 tons of carbon per hectare
