A detailed study has measured the combined threats that climate change and the loss of Indigenous languages pose to the biological and cultural wealth of the Amazon basin.

一項詳細研究衡量了氣候變遷與原住民語言流失，對亞馬遜盆地的生物與文化財富所造成的綜合威脅。

The researchers analyzed over 90,000 reports to identify 5,796 plant species used by people, which is about one-third of the region's seed plants. The data shows that Indigenous groups have much deeper botanical knowledge than non-Indigenous people, using 4,305 species compared to only 1,012. However, much of this knowledge is very specific; 74% of plant uses are known to only one culture, and 60% of these unique uses are linked to languages that are currently at risk of disappearing.

研究人員分析了超過 90,000 份報告，識別出 5,796 種被人類使用的植物，約佔該地區種子植物的三分之一。數據顯示，原住民群體對植物的認識遠深於非原住民，他們使用了 4,305 種植物，而後者僅為 1,012 種。然而，許多此類知識非常特定；74% 的植物用途僅由單一文化知曉，且其中 60% 的獨特用途與目前面臨消失風險的語言相關。

According to climate models, plants used by humans will likely see their habitats shrink more than non-used species by 2080, with medicinal plants being the most affected. Consequently, Indigenous cultures could lose between 28% and 34% of the plants they use, leading to a significant drop in the available plant services. Furthermore, the loss of threatened languages could cause a 26% reduction in the region's total knowledge pool. This loss could even reach 61% if more languages are included. The authors emphasized that these numbers are conservative because they do not include other pressures like deforestation and mining.

根據氣候模型，到 2080 年，人類使用的植物其棲息地縮減程度可能會比非使用物種更嚴重，其中藥用植物受影響最深。因此，原住民文化可能會失去 28% 至 34% 其所使用的植物，導致可用的植物服務大幅下降。此外，受威脅語言的流失可能會導致該地區總知識庫減少 26%。如果納入更多語言，此損失甚至可能達到 61%。作者強調，這些數字是保守估計，因為尚未計入如森林砍伐與採礦等其他壓力。

The Amazon's cultural and natural heritage faces a double threat from habitat loss and language extinction, which means we need combined conservation strategies across the entire region.

亞馬遜的文化與自然遺產面臨棲息地流失與語言滅絕的雙重威脅，這意味著我們需要在整個地區採取綜合保育策略。
