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

然而，这是要付出代价的。几乎一半的原始生物群已经摧毁。

The boreal forest, also known as Taiga, is the largest terrestrial biome on the planet.

北方为泰加，是地球上面积最大的陆地生群系。

The boreal forest is the largest terrestrial biome in the world.

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，而且大多数是未知的。

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。

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系统，除了最寒冷的北极地区外，所有地区都由植物支撑。

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

从不利的一面来看，山脉的存在只会扩大之前发展沙漠和丛生物群落的不利因素。

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大小的生物群落的核心部分。

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。

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

它由不同的生区域或生物群落组成，生物群落适应特定的气候条件。

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

北方森是世界上最大的陆地生物群落。 它占地球陆地面积的14%。

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

我们的生物群落越多样化，它们就越能抵御物种灭绝和食物网受到的威胁。

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，植物都扮演着重要的角色。

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，它是森和草原之间的过渡生物群落。

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的巨大生物群落。

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.

发现新的方块， 新的生物群落， 新的看待世界的方式。
