It requires growing young trees in a nursery that tree planters plant by hand.

这需要在苗圃中人工培育幼树。

Through that initiative, we will be planting a hundred million trees and inspiring five million tree planters around the globe.

通过这项倡议，我们将在全球种植一亿棵树，并激励五百万植树者行动起来。

Tree planting drones, for example, can plant up to 100,000 trees a day, the equivalent of about 50 veteran tree planters.

比如植树无人机，一天可以种 10 万株树，相当于 50 位经验丰富的造林员。

Up north, it wouldn't be uncommon for a tree planter to pee on their own hands to keep them from freezing.

在北部地区，造林员有时需要在手上小解来维持温度，以免双手冻僵。
