全球生態足跡網絡( Global Footprint Network)每年都會公布當年度的地球超載日,今年的地球超載日落在7/24,意味著我們只用7個月的時間,大約1.8倍的速度耗盡了地球一年可以產生的資源量,未來幾個月裡我們都是過著資源透支的生活!今年更是創下自1971年來最早的紀錄。

不容忽視的背後警示
這不僅僅是一個數字,它反映的是我們對地球資源的消耗速度已經超過了自然環境的自我恢復能力,像是二氧化碳的排放量已遠超過自然可吸存的量,淡水的消耗超過了自然補充的速度,捕魚的速度超過了魚類的繁殖的速度,林木砍伐的速度超過了森林經營的速度。這樣不平衡地的自然資源消耗,正危及長期資源安全,並帶來一系列負面後果 — — 如生物多樣性的喪失、毀林、極端氣候的加劇等。這些不僅影響了我們的生存環境,還將加劇了停滯性通膨、糧食和能源安全、健康危機以及衝突風險。對於本就脆弱度較高的人群與地區而言更是雪上加霜。儘管這15年來資源耗用的速度趨於平緩,但超載的損害是累積的,每一年的「赤字」支出,都在進一步加重我們的生態債務。
永續轉型
好消息是,我們在五個關鍵領域中,仍擁有推動地球超載日延後的機會:城市、能源、食物、人口和地球。全球生態足跡網絡提出100多個有潛力推動地球超載日的行動方案,例如,如果我們能將來自化石燃料的二氧化碳排放減少50%,就能將地球超載日推遲三個月。 推動永續發展的工作,正是協助企業進行轉型,讓它們在實現經濟效益的同時,也能顯著減少對環境的負面影響。那些積極推動永續轉型,降低資源超載的企業,將成為未來面對氣候變遷與資源限制時,最具價值的企業。然而,這不僅是政府與企業的責任,事實上,每個人都能成為改變的一部分,成為推動這場變革的齒輪。
另外關於地球超載日也許我們可以思考的:
“We are stretching the limits of how much ecological damage we can get away with. It is now a quarter into the 21st century and we owe the planet at least 22 years of ecological regeneration, even if we stop any further damage now. If we still want to call this planet home, this level of overshoot calls for a scale of ambition in adaptation and mitigation that should dwarf any previous historical investments we have made, for the sake of our common future.” -- Dr. Lewis Akenji, board member of Global Footprint Network.
“Earth Overshoot Day reminds us that humanity is overconsuming by borrowing from the future. Unchecked, this will lead to default as the environment will be too depleted to offer everything people need. Avoiding financial and ecological default depends on our ability and willingness to pay back the debt. The good news is that avoiding ecological default is possible: We have the economic ability. Let’s now develop the political willingness from individual consumer behavior all the way up to governments’ economic strategies.”--Dr. Paul Shrivastava, Professor at Pennsylvania State University and Co-President of the Club of Rome
“Because of the nature of physics, overshoot cannot last. It will end either by deliberate design or dumped-on disaster. It should not be too hard to choose which one is preferable, particularly in light of so many possible choices.”--
Dr. Mathis Wackernagel, Global Footprint Network co-founder and board member
