The article mentions ammonia, but what about methane? "Methane is the second-largest contributor to climate change and the majority of methane emissions caused by human activity comes from livestock." [1] How much methane is emitted by the act of farting, compared to the waste decomposing? I'm so glad that this research has succeeded, and here, because in a country like New Zealand there is political willpower (pro-environment) and industrial capacity (Fonterra dairy) to get this mooving. I wish I could give the researcher a pat on the back.
