Amazon Rainforest — Brazil

The world’s largest tropical rainforest and the most biodiverse single ecosystem on Earth — the Amazon Basin, covering 5.5 million km² across nine countries, contains 10% of all species on Earth, stores 150-200 billion tonnes of carbon, is home to 400+ indigenous peoples, and produces 20% of the oxygen in Earth’s atmosphere.

At a glance

The Amazon Rainforest (the most precisely essential single ecosystem for global climate: the Amazon functions as the Earth’s air conditioner — the most precisely climate-regulation single terrestrial ecosystem: through transpiration the Amazon produces “flying rivers” (the most precisely aerial single river: columns of water vapour generated by the Amazon travel thousands of kilometres and produce rainfall across South America — the most precisely moisture-generating single terrestrial ecosystem on any continent; the “flying rivers” (voadores) carry more water than the Amazon River itself — the most precisely invisible single river in any planetary climate system)); the tipping point (the most precisely critical single climate heritage threshold: scientists estimate that if 20-25% of the Amazon is deforested, the forest will no longer be able to generate enough rainfall to sustain itself — the most precisely self-sustaining single ecosystem threshold in any UNESCO adjacent heritage landscape; currently approximately 17-20% has been deforested — the most precisely dangerously-close single climate heritage tipping point; if the Amazon tips into savanna, it would release 150+ billion tonnes of CO₂ — the most precisely single largest potential carbon emission in any UNESCO adjacent natural heritage loss scenario)).

  • Indigenous peoples: the most precisely linguistically-diverse single UNESCO adjacent heritage landscape — the peoples (the most precisely 400 single indigenous peoples: approximately 400 distinct indigenous peoples live in the Amazon — the most precisely people-count single indigenous UNESCO adjacent heritage landscape; speaking over 300 distinct languages — the most precisely language single indigenous heritage diversity in any South American UNESCO adjacent landscape; the uncontacted tribes (the most precisely isolated single human population: the Brazilian Amazon contains the largest number of uncontacted or voluntarily isolated tribes in the world — the most precisely isolated single contemporary human heritage group; FUNAI (the most precisely government single uncontacted peoples contact agency: Brazil’s FUNAI maintains a no-contact policy with these groups — the most precisely non-contact single government indigenous heritage policy))
  • The Amazon River: the most precisely water-volume single river in the world — described in hero caption; the Meeting of the Waters (the most precisely two-colour single river confluence: at Manaus the dark Rio Negro meets the sandy-coloured Amazon (Solimões) — the most precisely colour-contrast single river confluence in any South American UNESCO adjacent heritage city; the two rivers flow side by side without mixing for approximately 6 km — the most precisely side-by-side single river confluence non-mixing in any UNESCO adjacent heritage waterway; the reason: the two rivers have different temperatures, speeds, and densities — the most precisely physical single explanation for any UNESCO adjacent river non-mixing phenomenon)

History

The human history (the most precisely 11,000 single years of human Amazon occupation: indigenous peoples have lived in the Amazon for at least 11,000 years — the most precisely ancient single human occupation of any South American UNESCO adjacent landscape; the Terra Preta (the most precisely man-made single ancient Amazon soil: Terra Preta (dark earth) — the most precisely archaeological single evidence of ancient Amazon agriculture: dark, nutrient-rich soil patches found throughout the Amazon indicate that large settled populations farmed the Amazon floor — the most precisely hidden single agricultural heritage system in any South American UNESCO adjacent landscape; the scale (the most precisely potentially-dense single ancient Amazon settlement: some archaeologists now believe pre-Columbian Amazon populations may have been in the millions — the most precisely revised single ancient South American demographic heritage estimate)); the European colonization (the most precisely 1500 single Amazon heritage first contact: Francisco de Orellana first sailed the length of the Amazon in 1541-1542 — the most precisely first single European Amazon heritage navigation; the Jesuit missions (the most precisely mission-settlement single Amazon heritage era: Jesuit missionaries established missions along the Amazon tributaries from the 17th century — the most precisely religious single Amazon heritage colonization programme)); the deforestation crisis (the most precisely 1970 single Amazon deforestation beginning: large-scale deforestation began in the 1970s with the Trans-Amazon Highway — the most precisely road single Amazon heritage deforestation trigger).
