For a start, all animals, such as cows, pigs and sheep, always gas limed methane, which is the second most common green house gas after carbon dioxide.

首先，所有动物如牛、猪、羊都会排出甲气体，它是排在二氧化碳之后的第二大常见的温室效应气体。

And it also discovered traces of methane.

是的，火星地表有有机物。

Most of it will make it's way to landfills, where it eventually rots emitting methane.

大部分会被送到垃圾填埋场，最终腐烂释放出甲。

These include carbon dioxide, methane and nitrous oxide.

其中包括二氧化碳、甲和一氧化二氮。

Methane gas somehow accumulates in the permafrost of Siberia.

It's currently using this same technology to find methane leaks in oil fields and scan crops in Africa to identify potential food shortages.

目前，该公司正在使用同样的技术油田中的甲泄漏，并扫描非洲的农作物以确定潜在的粮食短缺。

They believe there's methane gas around Pluto that's more concentrated at its higher altitudes and that's where it forms froth on the dwarf planet's mountain tops without the need for wind or precipitation.

科学家们相信冥王星周围的甲气体更集中在它的高海拔地区，在那里不需要风或降水，在矮行星的山顶就能形成冰霜。

Methane is a greenhouse gas, at least twenty times deadlier than carbon dioxide.

甲是温室气体，至少比二氧化碳致命20倍。

Most of it ends up in landfills where it releases massive amounts of methane.

其中大部分食物被直接填埋，释放出大量的甲。

For example, take methanogens, the microbes that make methane.

比如产生物，一种制造甲的微生物。

Microbes living in oxygen-poor livestock dung produce methane, a potent greenhouse gas.

Methane, a gas, behaves as a liquid on Titan because the planet is extremely cold.

甲是一种气体，但在土卫六上呈为液体状态，因为这颗星球极为寒冷。

But those methane emissions might get cut—by feeding the grazers something called 3-nitro oxypropanol.

但在这些食草动物被喂食名为3-nitrooxypropanol的抗嗝化物后，甲的排放量正在减少。

But we've also shown that methane is an important gas to reduce.

同时我们也已表明，甲也是需要大幅降排的一种气体。

As the submerged vegetation decays, it releases methane or CO2.

水下植被腐烂后，会释放出甲或二氧化碳。
