Deforestation of the Amazon rainforest , and recover of degraded pastures. In August 2017, Brazilian president Michel Temer abolished an Amazonian nature reserve the size of Denmark in Brazil's northern states of Pará and Amapá. Deforestation of the Amazon rainforest The cattle sector of the Brazilian Amazon, incentivized by the international beef and leather trades, has been responsible for about 80% of all deforestation in the region, or about 14% of the world's total annual deforestation, making it the world's largest single driver of deforestation. By 2017, 20% of land forested before 1970 in the Amazon had been deforested, and 90% of that been converted
Rainforest plays a significant role in causing rainforests to release carbon dioxide, as do other factors, whether human-induced or natural, which result in tree death, such as burning and drought. Some climate models operating with interactive vegetation predict a large loss of Amazonian rainforest around 2050 due to drought, forest dieback and the subsequent release of more carbon dioxide. Five million years from now, the Amazon rainforest may long since have dried and transformed itself into savannah, killing itself in the progress (changes such as this may happen even if all human deforestation activity ceases overnight). Tropical rainforests provide timber as
