And I guess with fewer places to inhabit, they concentrate in greater numbers in few areas, which surely makes them easier targets for the hunters.

而且我想，由于可居住的地方较少，它们集中在少数地区的数量较大，这肯定使它们容易成为猎人的目标。

That may sound pricey but that's still a fraction of what it costs now and that's because there are only two habitable locations off earth, the International Space Station and China's Space Station.

这听起来可很昂贵，但是这仍然只是现在成本的一小部分，因为在地球之外只有两个可居住的地方，际空间站和中的空间站。

Not just a spiritual sanctuary, the monastery was built next to Pile Gate so that the resident monks could rush to its defense in times of attack.

So really the presence of Jupiter may be one reason why we have life on Earth and habitability and be able to have the Earth nice environment instead of getting pummeled by so many comets.

这么看来木星的存在真的是地球产生生命的原因之一，通过打击大量的慧星，使地球成为可居住之地，有着好环境。

And it is because of this extreme isolation from the rest of the world, the New Zealand was always fated to be calm, the final large habitable landmass on the Earth's surface to ever be discovered by humans.

正是由于这种与世界其他地方的极端隔离，新西兰注定是平静的，注定是人类在地球表面发现的最后一大片可居住的陆地。

If you expand your understanding of the temperatures that life can handle or the types of elements that life can breathe, then suddenly a lot more habitable space on this planet opens up to you.

对于生命可以处理的温度或可以呼吸的元素种类，如果拓宽我们的理解，那么这个星球上突然向我们开放可居住空间。

There's about 24.6 million square miles of habitable land on Earth, so if we average out the space between every chimney, that gives us about 0.026 square miles per household.

地球上大约有 6370 万平方公里的可居住土地，所以如果我们给每个烟囱之间的空间取平均值，得出我们每个家庭大约 0.067 平方英里。

They're very particular in the kind of habitat where they can live which is part of what makes them so rare and amazing indicators for our water quality.

它们可居住的栖息地十分特别，这是使它们如此稀有的原因，也使得它们够成为检验水质的指标。

How they will explain our love of plastic or the fact that within a geological eyeblink, we exploded out of Africa to colonize virtually every inhabitable space on earth.

他们将如何解释我们对塑料的喜爱，以及我们在一眨眼的功夫就冲出非洲，几乎占领了地球上每一个可居住的空间。

Now, it doesn't look like we can even begin to identify this as a potential inhabitable place just yet because this planet has more acidity than you could handle.

现在，我们似乎甚至无法将其视为潜在的可居住之地，因为这颗行星的酸度比我们所应对的还要高。

That's not far enough for our planet to be out of the habitable zone, but how habitable would Earth be after five deadly seconds without gravity?

这还不足以使地球脱离可居住区，但五秒后，没有引力，地球将如何居住？

GUPTA (voice-over): Julie showed me around the mock-up of the station, which has 935 cubic meters of livable space.

Julie带我参观了车站的模型，有935立方米的可居住空间。

Confronting this challenge will require a sustained global effort to ensure that our planet remains a safe and livable place for future generations.

面对这一挑战需要全球持续的努力，以确保地球对子孙后代来讲依然是安全、可居住的环境。

Despite the building's height, the tower will contain just 58 habitable floors — far fewer than other skyscrapers that are comparable in size.

尽管这座建筑很高，但它将只包含 58 层可居住的楼层——远远少于其他规模相当的摩天大楼。

Secondly, methane would not last for long in atmospheres of habitable rocky planets without constant replenishment, possibly by living organisms, the researchers said.

其次，研究人员表示，如果没有活的机体的持续补充，甲烷在可居住的岩质行星的大气层中不会存在很长时间。

This huge contraction in livable space is being heaped on to the existing woes faced by insects from habitat loss and pesticide use.

这种可居住空间的巨大收缩正被堆积在昆虫因栖息地丧失和杀虫剂使用而面临的现有困境之上。

And the chance existence of meteoric iron here was a crucial part of making this region inhabitable for humans at all.

而这里陨铁的偶然存在是使这个地区对人类来说可居住的关键部分。

They did not see a lovely, habitable world: instead, what we got were photos of a dry, dead, forbidding planet.

但它们并非有发现一个可爱的可居住环境，而只得到了关于这颗干涸、枯死、严酷的行星的照片。

He added, " The formation date of the moon is important as only after that Earth became a habitable planet."

“月球的形成日期很重要，因为只有在月球形成之后，地球才成为可居住的行星。”
