These grasslands make up the largest biome in North America.

这些草原构成了美最大生物群落。

That's essentially a semi-arid steppe biome and an extension of the vast American Great Plains.

这基本上是半干旱草原生物群落，是广阔美大平原延伸。

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

然而，这是要付出代价。一半原始生物群已经被摧毁。

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

因此，这是球上非常重要生物群落，而且大多数是未知。

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

在世界14个受保护生物群落和栖息中，温带草保护水平最低。

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，除了最寒冷区外，所有区都由植物支撑。

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

从不利一面来看，山脉存在只会扩大之前发展沙漠和丛林生物群落不利因素。

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生物群落核心部分。

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

植物是每一个生物群落主要组成部分。

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

它由不同生态区域或生物群落组成，生物群落适应特定气候条件。

The more diverse our biomes are, the more security they have against species extinction and threats to their food webs.

我们生物群落越多样化，它们就越能抵御物种灭绝和食物网受到威胁。

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，植物都扮演着重要角色。

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

比如，想想水生或水基生物群落。

Take the savanna, for example — a transitional biome between forests and grasslands.

以稀树草原为例，它是森林和草原之间过渡生物群落。

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巨大生物群落。

I hope you enjoyed  this introduction to this aquatic biome.

我希望你喜欢这个介绍这个水生生物群系。

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

发现新方块， 新生物群落， 新看待世界方式。

There are almost no trees in this biome.

这个生物群系中没有树木。

The desert is the driest biome on Earth.

沙漠是球上最干燥生物群落。

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

大西洋雨林是球上受威胁最严重生物群落之一，有超过百分之九十森林被砍伐和破坏。
