年封存3萬噸碳排放
A new analysis by economists with the International Monetary Fund (IMF) points out that great whales can help humanity combat climate change by capturing carbon.
國際貨幣基金組織（IMF）的經濟學家進行的一項新分析指出，巨型鯨魚可捕捉大氣中的碳，幫助人類對抗氣候變遷。

Great whales help fight climate change by sequestering carbon in several ways.
巨型鯨魚通過多種方式封存碳，有助對抗氣候變遷，
sequester(v.)扣押(資産)、封存=capture and save
They capture carbon and hoard it in their fat and protein-rich bodies, stockpiling tons of the element like enormous trees in the ocean.
他們捕獲碳並將其儲存在富含脂肪和蛋白質的體內，就像海洋中的大樹一樣儲存了大量的碳。
hoard(v.)貯藏、囤積=store-rich 富含…的a protein-rich diet富含蛋白質的飲食stockpile(v.)囤積
When a whale perishes and its carcass sinks to the sea floor, that stored carbon is removed from the atmospheric cycle for hundreds to thousands of years.
當鯨魚死亡，屍體沉入海床，體內儲存的碳便等於被從大氣循環中移除，可封存於海底數百至數千年的時間。

Research published in 2010 estimated that eight types of baleen whales, including blue, humpback, and minke whales, altogether shuttle nearly 30,000 tons of carbon into the deep sea each year as their remains sink.
一項2010年發表的研究估計，每年八種鬚鯨類鯨魚，包括藍鯨、座頭鯨和小鬚鯨，死去後屍體沉沒，就會有將近3萬噸碳被封存進深海。

Moreover, the nutrients in whale excrement stimulate the growth of marine algae, which pull carbon out of the air via photosynthesis.
此外，鯨魚排泄物中的營養物質會刺激海藻的生長，海藻會透過光合作用將碳從空氣中抽出。

Another study found that 200,000 tons of carbon is drawn out of the atmosphere thanks to the iron-rich defecations of the 12,000 sperm whales in the Southern Ocean that give rise to phytoplankton.
另一項研究發現，南冰洋中1萬2千條抹香鯨富含鐵的排泄物刺激了浮游植物的生長，而浮游植物共吸收了20萬噸的碳。

There are currently about 1.3 million great whales around the world, but if they were protected and their populations rebounded to their pre-commercial whaling size of 4-5 million, the economists’ calculations show they could capture more carbon dioxide each year than the annual emissions of Brazil.
經濟學家計算目前全世界大約有130萬頭巨型鯨魚，但是如果牠們受到保護，且數量恢復到商業捕鯨前的規模，即400萬至500萬頭，那麼牠們每年可以捕捉的二氧化碳會比巴西一整年的排放量還要來得多。

However, even that just represents a small proportion of annual global carbon emissions, and economists say the concept should not be oversold.
然而，即便這也僅佔全球每年碳排放量的一小部分，經濟學家表示，不應該誇大保育鯨魚可對抗氣候變遷的概念，

Steven Lutz of GRID-Arendal, a foundation that works with the United Nations Environment Program, told National Geographic: “It’s not like we save the whales and we save the climate.”
與聯合國環境規劃署合作的GRID-Arendal基金會的史蒂文·盧茲（Steven Lutz）告訴《國家地理雜誌》：「不是拯救了鯨魚，就能拯救氣候。」
The framework of the analysis is aimed at policymakers who “don’t buy into saving animals for the sake of animals,” said the lead economist of the study, Ralph Chami.
IMF經濟學家拉爾夫·查米表示，分析的架構旨在說服那些「不相信需要為了動物而保育動物的」決策者。
