Methane, there are certainly some solid bonds there, but breaking those to form CO2 and water, well it's worth it, right, energetically.
酒精中的确含有很强的化学键,但是打断这些化学键然后生成二氧化碳和水,从能量上来看是值得的。
And so I think we need to take action as soon as possible to start reducing carbon dioxide emissions.
所以我觉得我们需要尽快开始行动,减少二氧化碳排放。
You burn methane, and it combines with oxygen to form water, to form CO2.

The main goal of the respiratory system is to bring fresh in so that you can extract oxygen from it, and blow used air out so that you can rid of carbon dioxide which is the end product of carbon metabolism inside our bodies.
呼吸系统的主要功能是,吸入新鲜空气,以便获得空气中的氧气,呼出废气,以便排出二氧化碳,二氧化碳是人体内碳代谢的终产物
In fact, it's interesting to note that the first calculation on the impact of CO2 on climate was done in the late 1800's by Arrhenius.
很有趣地,是阿列纽斯在19世纪末,第一个做了的关于二氧化碳,对气候的影响的计算。
