Video Description

P來賓|中山大學海洋科學系特聘教授 洪慶章 ​ 來自氣候變遷的威脅,讓世界各國共同提出「2050淨零排放」的宣示與行動,而為了達到2050年碳中和目標,發展固碳技術已成為世界趨勢。然而,究竟什麼是「碳」、要固什麼「碳」?又該怎麼固呢? ​ 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? ​ 00:00 精彩片段 00:34 節目開始 02:04 海藻與海菜也能減碳固碳? 04:39 海木耳吸碳能力是世界第一等? 12:26 海木耳可以有碳匯嗎? 15:23 海木耳怎麼養? 21:56 國外的研究成果有什麼發現? 23:25 藍碳固碳能力如何呢 25:46 是否有相關政策?海洋藍碳如何跨部會治理? 28:46 海木耳可以取得碳權認證嗎 33:04 海中的自然碳匯 35:53 關於藍碳的研究推廣與養殖 還可以做哪些事? ​ ​ ▼本集相關專題 翻滾海藻|東北角的海底繁盛花園 https://youtu.be/rTJooku9acU 澎湖的季節限定|系列三:紫菜養殖的氣候挑戰 https://youtu.be/uQpZXEO-E-Q ​ ​ ​ ​ ▼【零碳經濟系列】我們的島 Podcast ●第一堂課|站在減碳時代的關鍵時刻,台灣該如何因應?|ft.台師大永續管理與環境教育所教授 葉欣誠 https://youtu.be/DB-IMgq8XlY ●第二堂課CBAM浪潮下鋼鐵與扣件業的存亡關頭?或轉型契機?|ft.中經院綠色經濟研究中心分析師 李盈嬌 https://youtu.be/B8NXemxnGLg ●第一堂課|碳權如何產生?碳權怎麼交易與認證?一起來認識臺灣第一間碳權交易所!|ft.臺灣碳權交易所董事 劉哲良 https://youtu.be/IgmTKX3IROw ●第四堂課|碳稅?碳費? 當二氧化碳成為可被交易與課稅的商品,以價制量可行嗎?|FT.中研院經濟研究所兼任研究員蕭代基 https://youtu.be/nB10ElUm5jk ​ ​ ​ ​ #藍碳#藍金#海木耳#吸碳高手#碳匯功能#2050淨零減碳 ​ ​ ​ ​ ※關注我們的島 追蹤 守護環境議題》 👉我們的島官網 http://ourisland.pts.org.tw 👉我們的島粉絲專頁 https://www.facebook.com/PTSourisland 👉我們的島推特 https://twitter.com/ourisland 👉我們的島IG https://www.instagram.com/pts_ourisland ​ ​ \每週日,晚上九點,和我們一起來了解更多你我環境中的問題吧!/ (週間還會不定時更新環境時事 記得要訂閱、追蹤、分享啦!)
