Susan Graham: A new way to restore Earth's biodiversity -- from the air | TED

譯者: Carol Chen 審譯者: Amanda Zhu

Every year, humans change 10 million hectares of land,

人類每年改變了約一千萬公頃的土地

and not for the better.

帶來的卻是破壞

Right now, there are more than two billion hectares of degraded land

大於二十億公頃的土地 正在世界各地退化中

around the world.

We need to fix this fast, and technology can help.

我們需要儘快阻止繼續惡化 而科技可助一臂之力

Restoration is an enormous, complex challenge.

恢復土地的樣貌 是一個巨大且複雜的挑戰

It cannot be done by simply planting trees.

單單依靠種植樹木是做不到的

We need to bring native, complex ecosystems back to life,

我們需要使天然而複雜的 生態系統重新復甦

and it requires deep ecological expertise.

但只有具備深度 生態知識的專家才做得到

Until now, we have been limited to poor facsimiles,

直到今天，我們用的 依舊是差勁的生態模擬

like vast plantations of a single kind of tree.

像是大量種植單一樹種

But drones change that by allowing us to gather data

但無人機問世改變了一切

我們得以收集數據

and plant the right mix of vegetation quickly, at enormous scales.

並大規模且快速地種植 由多種植物構成的適當植被

And machine-learning analysis enables us to plan the planting

機器學習分析讓我們能有計劃地種植

and then monitor our restoration work.

然後監控復原的狀況

For example, in Australia,

例如，我們在澳洲

we're using drone-based planting and ecology-trained AI

正以無人機為主的種植技術 以及受過生態訓練的人工智能

to restore thousands of hectares of land mined for coal.

復原數千公頃煤礦舊址

Not just planting trees,

我們不單單只是種樹

but bringing back biodiverse, complex ecosystems.

而是帶回生物多樣性 及複雜的生態系統

On a larger scale, native forests here in Australia

澳洲這裡有大規模的原始森林

have been decimated by catastrophic bushfires

早已經因為災難性的叢林大火 以及農業土地開墾

and land-clearing for agriculture.

而受到嚴重破壞

This means diminished food sources and safe habitats for koalas.

這意味著無尾熊的食物來源 和安全棲息地縮減

A new project would allow us to accelerate

有個新方案讓我們得以 在接下來的幾年內

the restoration of thousands of hectares of koala forests

加速修復數千公頃無尾熊棲息的森林

over the next few years.

With these combined technologies,

這些科技的綜合應用

we're able to scale up restoration

讓我們可以擴大修復範圍

from a small island to an entire continent.

小至一個小島，大至整個陸塊

我們可以把舊時的採礦地回復為森林

We can return forests to land where a mine used to be,

or recreate ecosystems

或是重建生態系統

like the one we're hoping to restore on Lord Howe Island,

就像我們正在復原的豪勳爵島

birthplace of one of the world's largest insects.

世界上一種最巨型昆蟲的發源地

This unique island is plagued by imported species,

這個獨特的島受到 大量進口物種的嚴重干擾

where we're helping to eradicate the undesirable plants

我們正著手消除不該存在於此的植物

to allow endemic species to thrive.

讓原生物種繁榮茁壯

It's not just billions of trees.

這不僅僅關乎數十億棵樹

It's restoring nature in all its complexity and beauty.

而是還原大自然系統原有的複雜與美

Thank you.

謝謝
