吸收六億噸CO2
Seaweed is a general term for thousands of species of plant-like marine algae that are categorized into groups based on color, including green, brown and red.

marine (adj.)海洋的 (n.)海軍陸戰隊士兵algae (n.)藻類（單數為alga）categorize (v.)分類；category (n.)類別
Seaweed used to be considered a simple plant, but now scientists classify it as something else because of its unique structure; unlike plants, seaweed can absorb minerals and gases directly from seawater through its blades.
海藻曾被認為是簡單的植物，但現在科學家因為其獨特的結構而將之另外歸類；有別於植物，海藻能透過它的葉片直接從海水吸收礦物質和氣體。
classify (v.)將……分類；classify A as(under) B 將A歸類為Bmineral (n.)礦物質；mineral water 礦泉水
In the marine ecosystem, seaweed plays a very important role.

excess (adj.)多餘的；excessive (adj.)過度的、極度的
Kelp is one of the species of seaweed that is crucial to fighting climate change.
昆布是能對抗氣候變遷的重要海藻品種之一。
crucial (adj.)重要的、決定性的
Much like trees that absorb carbon dioxide and release oxygen, kelp absorbs up to 600 million tons of carbon every year while accounting for around 70% of the oxygen on Earth.
就如同樹木吸收二氧化碳並釋放氧氣一樣，昆布每年吸收高達六億噸的碳，並產出地球上約70％的氧氣。
account for （數量上）佔……比例
In addition to growing seaweed for food and other uses, some scientists believe that farming seaweed can effectively reduce emissions by absorbing and storing carbon dioxide as biomass.
海藻除了可以種來當糧食和其它用途之外，有些科學家認為種植海藻能藉由吸收二氧化碳並將其儲存為生物質，進而有效減少排放量。
emission (n.)排放、排放量；greenhouse gas emissions 溫室氣體排放store (v.)儲存
Therefore, seaweed’s importance may grow as a means to help the world combat climate change.
因此，海藻作為能幫助世界對抗氣候變遷的手段，其重要性與日俱增。
