Because a new study shows that temperature controls where soil-dwelling microbes live.

因为一项新研究显示气温能控土壤在哪存。

And then the soil microbes are decomposing things.

然后土壤正在分解东西。

Microbes in the soil can also produce nitrogen for the crop.

土壤中的也可以为农作产氮。

But the weirdest reason it's tough to compost meat and dairy is how delicious soil microbes find animal protein.

但最奇怪的理由是，把要肉和奶成堆肥，是很困难的，因为土壤会发现动蛋白非常“美味”。

We try to feed the microbes in the soil to help do the work, to help grow the grass.

我们也试着培育土壤里的来助土壤长。

A few years back, scientists found a soil microbe called Chromobacterium CspP living in the guts of mosquitoes in Panama.

几年前, 科学家们在巴拿马的蚊子身上发现了一种被称为色素细菌CspP的土壤。

They use a soil microbe to transform loose aggregates, like sand or crushed stone, into a biofabricated, or biocement, brick.

他们使用一种土壤，将砂砾或碎石之类的碎颗粒转换成造的砖头，又称水泥砖。

And so, we invented fertilizer and we've caused those microbes in the soil to go into hibernation.

所以我们发明了肥料，使土壤中的进入冬眠状态。

There is more microorganisms in this teaspoon of soil from this farm than there are people on the planet.

这个农场的一茶匙土壤中有的数量比地球上的人还多。

The planet also relies on soil microbiomes for other essential services.

地球还依赖土壤群来提供其他基本服务。

So they even started to say, oh yeah, preserve the microbes in the soil like granddad used to do.

所以他们甚至开始说，哦，是的，我们应该像爷爷以前做的那样保护土壤中的。

Another way that soil microbiomes can be part of the climate change solution is by building healthy soil.

土壤组可以成为气候变化解决方案一部分的另一种方式是建设健康的土壤。

That's because plants trap carbon dioxide by photosynthesis, and soil microbes emit it by the process of respiration.

这是因为植通过光合作用捕获二氧化碳，而土壤通过呼吸过程释放二氧化碳。

And in one teaspoon of soil, there are more microorganisms than there are people on the Earth.

在一茶匙土壤中，的数量比地球上的人口还要多。

As an ecologist and climate scientist, I've been studying the microbes that live in soil for 20 years now.

作为一名态学家和气候科学家，我研究土壤中的已有 20 年了。

They may be harder to see, but microbiomes in the soil are just as important as the human or ocean microbiome.

它们可能更难看到，但土壤中的群与人类或海洋群一样重要。

And even though composting is all about getting friendly soil organisms to break stuff down for us, we don't want them to get too excited.

尽管堆肥是为让土壤来我们分解质，但我们并不希望它们太活跃。

So the next time you support an environmental cause, maybe through a nonprofit donation or volunteer work, remember, soil microbes need conservation too.

所以下次你支持环保事业时，也许通过非营利性捐赠或志愿者工作， 请记住，土壤也需要保护。

So, when we started breeding plants so that every harvest would produce more yield, we needed more nitrogen than the microbe in the soil could provide.

所以当我们开始耕种时每次收成都会产更多产量的植，我们需要的氮比土壤中的可以提供的要多。

Just like we've seen with the human microbiome, cutting-edge techniques in molecular biology, especially DNA sequencing, show that soil microbiomes are extremely diverse in their genes and life cycles.

就像我们在人类组中看到的那样， 分子学的尖端技术，尤其是 DNA 测序， 表明土壤组的基因和命周期极为多样化。
