アマゾン熱帯雨林の火事では、アマゾンが生成する酸素の量に様々な意見が出されており、「アマゾンは地球の酸素の20%を生産」は誤りとする記事もあります。
一方、生物多様性の観点からは、極めて重要な役割を担っています。アマゾン川は長年生態的条件や気象的条件が比較的安定していたため、セルバと呼ばれる熱帯雨林や水中の世界でも、豊かで多様性に富んだ動植物が数多く見られます。アマゾン川流域には、約250種類の哺乳類、約1,800種類の鳥類、特に昆虫全体に至っては、100万種以上が生息していると推測されています。

[Earthview Wonders] No.849: Amazon River
Astronaut Sergey Ryazansky captured from ISS the Amazon River. There are various opinions on the oxygen production amount, and the National Geographic came out with an article Why the Amazon doesn’t really produce 20% of the world’s oxygen.
On the other hand, Amazon is critical for second-to-none place for
More than one-third of all known species in the world live in the Amazon rainforest, a giant tropical forest and river basin with an area that stretches more than 5,400,000km2. It is the richest tropical forest in the world in terms of biodiversity. There are over 3,000 species of fish currently recognised in the Amazon basin, with more being discovered every year.In addition to the thousands of species of fish, the river supports crabs, algae, and turtles.
The local scenery on the ground is as follows.
