This is a problem; sharks scare away other creatures, such as sea turtles, and these creatures eat seagrass, which absorbs a lot of carbon from the atmosphere.
这是一个问题；鲨鱼会吓跑其他生物，比如海龟，而这些生物会吃掉海草，海草能吸收大气中大量的碳。
How climate change affects animal migration ⏲️ 6 Minute EnglishSo, basically, when the sharks are around, there's more seagrass on the ocean floor and so more carbon is absorbed.
所以，基本上，当有鲨鱼出没时，海底的海草就会更多，从而吸收更多的碳。
How climate change affects animal migration ⏲️ 6 Minute EnglishResearch that we worked on shows that by just managing about 10 groups of animals, we could be taking out or sequestering more CO2 from the atmosphere by about six gigatonnes of carbon per year.
我们参与的研究表明，仅通过管理大约 10 个动物群体，我们每年就能从大气中清除或封存约 60 亿吨碳。
How climate change affects animal migration ⏲️ 6 Minute EnglishCreating breathable air in space has two requirements: supplying oxygen and removing exhaled carbon dioxide before it builds up.
在太空中制造可呼吸的空气有两个要求：供应氧气，并在呼出的二氧化碳积聚之前将其清除。
How does the space station never run out of oxygen? - Alvaro Romero-Calvo and Theo St FrancisCanisters containing lithium hydroxide would chemically react with carbon dioxide, scrubbing it from the cabin.
装有氢氧化锂的罐体会与二氧化碳发生化学反应，将其从舱内清除。
How does the space station never run out of oxygen? - Alvaro Romero-Calvo and Theo St FrancisHydrogen gas is either vented into space or routed to a reactor, where it combines with captured exhaled carbon dioxide to make methane and water.
氢气要么被排入太空，要么被输送到反应器中，在那里与捕获的呼出二氧化碳结合，生成甲烷和水。
