Deforestation and climate change, via increasing dry-season length and drought frequency, may already have pushed the Amazon close to a critical threshold of rainforest dieback.
The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]

“If the Amazon rainforest is to avoid the tipping point, Indigenous people will have been a determinant factor," Miller said. Wildfires and extreme drought. Forest loss in Brazil’s Amazon — home to the largest swath of this rainforest — dropped 30.6% compared to the previous year, the lowest level of destruction in nine years. The ...
Since tropical rainforests are estimated to hold 50% of the planet's species, the canopy of rainforests worldwide may hold 45% of life on Earth. The Amazon rainforest borders eight countries, and has the world's largest river basin and is the source of 1/5 of the Earth's river water. It has the world's greatest diversity of birds and freshwater ...
