The Amazon fires have finally started to garner the attention of the world. The wildfires and deforestation, mostly in Brazil, are an ecological, political, and societal disaster.

亞馬遜大火終于開(kāi)始引起世界關(guān)注了，主要出現(xiàn)在巴西境內(nèi)的野火和森林砍伐是一場(chǎng)生態(tài)、政治和社會(huì)災(zāi)難。

The rainforest ecosystem provides oxygen, takes in carbon dioxide, supplies water vapor for the global weather-climate system, and hosts untapped medicinal benefits.

雨林生態(tài)系統(tǒng)釋放氧氣、吸收二氧化碳、為全球氣候系統(tǒng)提供水汽，還有未開(kāi)發(fā)的藥用價(jià)值。

The loss of trees and the sun-blotting smoke are obvious consequences of these massive fires. However, there is another problem with these wildfires.

這些大火明顯造成了樹(shù)木的損失，產(chǎn)生了蔽日的濃煙，但野火還有另外一個(gè)問(wèn)題。

They are emitting a lot of carbon monoxide. Here's why that is a problem.

大火釋放大量一氧化碳，下面說(shuō)明一下為什么這是個(gè)問(wèn)題。

I suspect that most people have some familiarity with carbon monoxide because it can be harmful to humans.

我猜大多數(shù)人對(duì)一氧化碳比較熟悉，因?yàn)樗鼘?duì)人體有害。

If exposed to it for even short period of time, carbon monoxide can quickly replace oxygen in the blood, which can cause serious or even fatal outcomes according to the Occupational Safety and Health Administration (OSHA).

據(jù)美國(guó)職業(yè)安全與健康管理局（OSHA）稱(chēng)，如果暴露在一氧化碳中即使很短一段時(shí)間，一氧化碳會(huì)快速替換血液中的氧氣，造成嚴(yán)重甚至致命的后果。

The gas is odorless, colorless, and tasteless so it is particularly dangerous.

這種氣體無(wú)臭、無(wú)色、無(wú)味，所以特別危險(xiǎn)。

According to a NASA press release from the Jet Propulsion Laboratory this week, the carbon monoxide signature of the Amazonian fires are clearly detectable by specialized Earth-monitoring satellites.

據(jù)NASA噴氣推進(jìn)實(shí)驗(yàn)室本周發(fā)布的新聞稿稱(chēng)，專(zhuān)門(mén)的地球監(jiān)測(cè)衛(wèi)星清楚地探測(cè)到亞馬遜大火的一氧化碳特征。

The image above was captured by an instrument called the Atmospheric Infrared Sounder (AIRS) aboard the Aqua satellite.

上圖就是Aqua衛(wèi)星上的大氣紅外探測(cè)器（AIRS）捕捉到的畫(huà)面。

In the animation, it is clear that the plume of carbon monoxide starts in the region of burning fires and then drifts southeastward into Brazil and other parts of the continent.

動(dòng)畫(huà)中清晰顯示二氧化碳羽流開(kāi)始于大火燃燒地區(qū)，然后向東南漂移到巴西和南美洲其他地區(qū)。
