So this is now a really significant biome on earth, and it's largely unknown.

因此，这是地球上非常重要的生物群落，且大多数是未知的。

Temperate grasslands have the lowest level of protection of the world's 14 recognised “biomes”, or habitats.

在世界14个受保护的生物群落和栖息地中，温带草地的保护水平最低。

Like, think about an aquatic — or water-based — biome.

比如，想想水生或水基生物群落。

The boreal forest is the largest terrestrial biome in the world. It covers 14 percent of the land on earth.

北方森林是世界上最大的陆地生物群落。 它占地球陆地面积的14%。

On the bad side, the presence of mountains only amplifies the previous negatives with developing desert and jungle biomes.

从不利的一面来看，山脉的存在只会扩大展沙漠和丛林生物群落的不利因素。

And plants are a major part of nearly every single biome.

植物几乎是每一个生物群落的主要组成部分。

The Atlantic rainforest is one of the planet's most threatened biomes, more than 90 percent of it was deforested and destroyed.

大西洋雨林是地球上受威胁最严重的生物群落一，有超过百分九十的森林被砍伐和破坏。

That came at a price, however. Almost half of the original biome has been destroyed.

然，这是要付出代价的。几乎一半的原始生物群已经被摧毁。

Okay, that's better — with biomes, the largest units that ecologists use to describe the plant life of different locations.

好吧，这就更好了——生物群落，生态家用来描述不同地区植物生命的最大单位。

It's made up of different ecological regions, or biomes, where communities of organisms are adapted to specific climate conditions.

它由不同的生态区域或生物群落组成，生物群落适应特定的气候条件。

The nodules are a core part of a biome roughly the size of the Amazon rain forest, she notes.

她指出，这些结核是一个大致相当于亚马逊雨林大小的生物群落的核心部分。

Each biome contains multiple ecosystems, and all but the most frigid arctic regions are supported by plants.

每个生物群落都包含多个生态系统，除了最寒冷的北极地区外，所有地区都由植物支撑。

To discover new blocks, new biomes, new ways of looking at the world.

现新的方块， 新的生物群落， 新的看待世界的方式。

This is a huge biome that we carry in our bellies every single day.

这是我们每天都在肚子里携带的巨大生物群落。

Freshwater biomes include rivers and streams, ponds and lakes, and wetlands.

淡水生物群落包括河流和溪流、池塘和湖泊以及湿地。

But no matter how many biomes there are, plants have important roles to fill in them.

但无论有多少生物群系，植物都扮演着重要的角色。

They're only a few meters thick, but they support all agriculture and every single terrestrial biome.

它们只有几米厚，但它们支撑着所有农业和每一个陆地生物群落。
