Humans, now the dominant species, will either lead the biosphere towards a flourishing future or to catastrophe.

We need to have the biosphere properly explored so that we can understand and competently manage it.

我们需要对生物圈正确地进行探测，唯有如此，我们才能把握其秘密，并更好的加以保护。

The broiler chicken, Bennett says, is now a symbol of how the biosphere is unrecognizable from its pre-human state.

贝内特说，这只肉用鸡现在是生物圈从其原始人类状态无法识别的一个象征。

Without insects, the biosphere — the living parts of the Earth — would rot because of the loss of insect decomposers.

如果没有昆虫，生物圈——地球上有生命的部分——将会因为失去昆虫分解者而腐烂。

Crucially, the people of that time had to arrange to pay themselves to do the things necessary to heal the biosphere.

关键的是，那时候的人还需要花费资金去做修复生物圈的必要工作。

The biosphere is all living things, from single-celled bacteria to plants and animals.

生物圈是所有生物，从单细胞细菌到植物和动物。

The biosphere is forever innovating in this kind of waythat's not a deduction.

生物圈永远以这种方式创新——这不是演绎。

An army of nanobots, tiny self-replicating robots, could destroy the biosphere.

-纳米机器人大军，微型自我复制机器人，可以摧毁生物圈。

And in the biosphere, the evolution of novel species was even slower.

而在生物圈中，新物种的进化就更慢了。

The biosphere has been bubbling forth for four billion years, creating new possibilities in the universe in that bubbling.

生物圈已经冒泡了四十亿年，在冒泡中为宇宙创造了新的可能性。

But most of the biosphere's usable nitrogen is the result of bacteria employing an enzyme called nitrogenase to pull nitrogen out of the air.

但生物圈中的大部分可用氮都是细菌利用一种名为固氮酶的酶氮气从空气中分离出来的。

In terms of proving grand ecological truths, the Biosphere 2 experiments were something of a bust.

就证明宏大的生态真理而言，生物圈二号实验是失败的。

Those news editors are sacrificing their integrity for clicks, and polluters are sacrificing the biosphere for profit.

那些新闻编辑为了点击量而牺牲了自己的诚信，而污染者为了利润而牺牲了生物圈。

The finding indicates that the biosphere more than three billion years ago was much more complex than previously appreciated, and perhaps had already colonized land.

该研究表明30多亿年前的生物圈比我们目前推测的要复杂得多，而且也许已延伸到了陆地。

I would like us to think of ourselves as citizens of the Earth, not just of the human world, but the whole living system, the biosphere.

我希望我们把自己看作地球的公民，不仅仅是人类世界的公民，而是整个生命系统，生物圈的公民。

There may be a temptation to treat the biosphere holistically and the species that compose it as a great flux of entities hardly worth distinguishing one from the other.

也许有些人会走捷径，用一种整体的视角来看待整个生物圈, 将其中的物种看成是个体的流动, 无须区分出它们之间的细微差别。

(Laughter) We can't deduce what is in the biosphere and will become, but we can make a mathematical theory of the statistics of the process.

（笑声）我们无法推断生物圈现在是什么以及将会变成什么，但是我们可以对这个过程的统计建立一个数学理论。
