海底最強的固碳高手 The strongest of carbon sequestration under the se

談到固碳，通常民眾第一個想到的是要多種樹、養森林，即所謂的綠碳。然而，臺灣四面環海，沿岸有豐富的「藍碳」生態系，包括紅樹林、海草床、鹽沼、海藻、珊瑚礁等，具強大碳匯功能的海洋逐漸受到重視。
事實上，地球上的生物多半屬於「碳基生物」，「碳」是組成生命體的重要元素，根據「碳」的來源與儲存，科學家將其分為：灰碳、黑碳、棕碳、綠碳、藍碳等等。我們的島Podcast這集要來談的就是「藍碳」，藍碳指的是被海洋生物從大氣中吸收與儲存在生態系的碳。
中山大學海洋科學系特聘教授洪慶章的團隊就發現，「海木耳」的固碳率，每年每公頃可達30噸，是臺北大安森林公園的2倍，研究團隊還蓋了「海藻公寓」來研究這個固碳明星。
外觀看似牡丹花、在日本被視為「長壽菜」的海木耳，由於營養好吃、經濟價值高，被譽為海中蔬菜之首。然而，它不只是美味的食材，更是吸碳高手？為何海木耳相較其他藻類可以吸附更多的碳？可以透過養海木耳而獲得碳權嗎？大規模養育海木耳，需要哪些資源，會遭遇哪些困難？對生態保育有什麼幫助？養育海木耳來吸碳，真的有足夠效益嗎？臺灣現有海藻中，還有多少固碳高手呢？究竟該如何將大氣中的二氧化碳，成功留在海洋中？
When it comes to carbon sequestration, the first thing people usually think of is planting more trees and raising forests, which is the so-called green carbon. However, Taiwan is surrounded by sea, and there are rich "blue carbon" ecosystems along the coast, including mangroves, seagrass beds, salt marshes, seaweeds, coral reefs, etc. The ocean has a strong carbon sink function and is gradually receiving attention.
In fact, most of the organisms on the earth are "carbon-based organisms". "Carbon" is an important element that makes up living organisms. According to the source and storage of "carbon", scientists divide it into: gray carbon, black carbon, brown carbon, Green carbon, blue carbon, etc. This episode of Our Island Podcast is going to talk about "blue carbon". Blue carbon refers to the carbon absorbed from the atmosphere by marine life and stored in the ecosystem.
The team of Distinguished Professor Hong Qingzhang of the Department of Marine Science at Sun Yat-sen University found that the carbon sequestration rate of "sea fungus" can reach 30 tons per hectare per year, which is twice that of Daan Forest Park in Taipei. The research team also built a "seaweed apartment" to study This carbon sequestration star.
Sea fungus, which looks like a peony flower and is regarded as a "longevity vegetable" in Japan, is known as the top vegetable in the sea due to its delicious nutrition and high economic value. However, it is not only a delicious ingredient, but also a master of carbon absorption? Why can sea fungus absorb more carbon than other algae? Can carbon rights be obtained by raising sea fungus? What resources are needed to raise sea fungus on a large scale, and what difficulties will you encounter? How does it help ecological conservation? Is it really beneficial enough to raise sea fungus to absorb carbon? How many carbon sequestration masters are there among Taiwan’s existing seaweeds? How to successfully keep carbon dioxide in the atmosphere in the ocean?
