翻译人员: Mo Zhang 校对人员: Cissy Yun

Every year, humans change 10 million hectares of land,

每年，人类会改变 1000 万公顷的土地，

and not for the better.

但并没有把它们变得更好。

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

目前，全世界有超过 20 亿公顷 的土地已经退化。

around the world.

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

我们需要马上解决这个问题， 科技可以帮助我们。

Restoration is an enormous, complex challenge.

土地复垦是个巨大而又复杂的挑战。

It cannot be done by simply planting trees.

不能简单依靠植树来解决。

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

我们需要让本土、复杂的 生态系统恢复生机，

and it requires deep ecological expertise.

这需要深厚的生态专业知识。

Until now, we have been limited to poor facsimiles,

到目前为止， 我们一直局限于单一的模式，

like vast plantations of a single kind of tree.

比如广泛种植一种类型的树木。

But drones change that by allowing us to gather data

但无人机改变了这一点， 它能让我们收集数据，

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

并大规模地迅速种植 恰当的植被组合。

And machine-learning analysis enables us to plan the planting

机器学习使我们 能够对种植进行规划，

and then monitor our restoration work.

然后监督我们的修复工作。

For example, in Australia,

例如，在澳大利亚，

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

我们正在利用无人机种植 和接受过生态培训的人工智能

to restore thousands of hectares of land mined for coal.

来修复数千公顷的煤炭开采土地。

Not just planting trees,

不仅仅是植树，

but bringing back biodiverse, complex ecosystems.

还要恢复生物多样性 和修复复杂的生态系统。

On a larger scale, native forests here in Australia

更大范围的来说， 澳大利亚的原生森林

have been decimated by catastrophic bushfires

已经被灾难性的森林大火 和农业开垦所摧毁。

and land-clearing for agriculture.

This means diminished food sources and safe habitats for koalas.

这意味着考拉的食物来源 和安全的栖息地在减少。

A new project would allow us to accelerate

一个新项目可以让我们 在未来几年内

the restoration of thousands of hectares of koala forests

加速修复数千公顷的考拉森林。

over the next few years.

With these combined technologies,

通过这些技术的结合，

we're able to scale up restoration

我们能将修复范围

from a small island to an entire continent.

从一个小岛扩展到整个大陆。

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

我们可以把曾经是矿井的地方 恢复到绿树成荫，

or recreate ecosystems

或者重建生态系统，

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

比如我们正在重建豪勋爵岛上 的生态系统，

birthplace of one of the world's largest insects.

那里诞生了世界上最大的昆虫之一。

This unique island is plagued by imported species,

这个独特的岛屿 受到外来物种的入侵，

where we're helping to eradicate the undesirable plants

我们正在消除对生态环境不利的植物，

to allow endemic species to thrive.

来让本土特有物种茁壮生长。

It's not just billions of trees.

这不仅仅是种植数十亿棵树。

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

这是恢复大自然本身的复杂和美丽。

Thank you.

谢谢。
