For centuries, giant sequoias were considered nearly indestructible, standing tall through millennia.
數百年來，巨杉被視為幾乎不可摧毀的，屹立千年。
However, recent evidence shows that these ancient giants now face an existential threat.
然而，最近的證據顯示，這些古老的巨木正面臨生存威脅。
Historically, sequoias relied on low-intensity fires to clear underbrush and encourage growth.
過去，巨杉依賴低強度火災來清理林下灌木並促進生長。
Unfortunately, a long-standing policy of total fire suppression caused hazardous 'ladder fuels' to accumulate, turning modern forests into tinderboxes.
遺憾的是，長期執行的全面滅火政策導致危險的「階梯式易燃物」堆積，使現代森林變成火藥庫。
As climate change brings hotter, drier conditions, wildfires have become alarmingly intense.
隨著氣候變遷帶來更炎熱、更乾燥的條件，野火變得異常猛烈。
By strategically using controlled fire to reduce fuel loads, land managers can drastically improve survival rates.
通過戰略性地使用受控火燒來減少燃料載荷，土地管理者能顯著提高樹木的存活率。
The data is compelling—trees in areas treated with prescribed burns were nearly four times more likely to survive recent catastrophic wildfires.
數據極具說服力——經受控火燒處理區域的樹木，在近期災難性野火中的存活機率幾乎是未處理區域的四倍。
In fact, these efforts saved nearly 1,900 sequoias during recent fire events.
事實上，這些努力在近期火災中挽救了近1,900棵巨杉。
By shifting from suppression to mimicking natural fire patterns, we are finally giving these majestic giants the best chance to thrive in a changing world.
透過從滅火轉向模擬自然火災模式，我們終於為這些雄偉的巨木提供了在變動的世界中繁茂生長的最佳機會。
Restoring fire is no longer just an option; it is essential for the survival of the world's largest trees.
恢復火災不再僅僅是一個選項；這對於全球最大樹木的存續至關重要。
