Summary
The paper deals with the complexity of the rumen microbiota and deals with it predominantly by reporting the type and amount of different microorganisms interacting. The fact that only 15% of the microbiota is known poses the article in the condition of a general statement of the importance of the complexity, but forces to postpone a more accurate modelling to the time when better techniques will give more accurate pictures of the microbes present and interacting.

Relevance for Complex Systems Knowledge
The paper is important for 0the sustainable development, in fact deals with the possibility of simple means to reduce methane production by cattle, considering the danger of this greenhouse gas, much more dangerous than carbon dioxide

Point of Strength
It is an important piece of biological history, because it depicts the situation of 2011 when the metagenomic studies were at their beginning. Furthermore, it poses an interesting theoretical question on whether the complexity of a system (and therefore its resilience) producing harmful outputs can be overcome by simple tools. In other words, it is interesting because it underlines how the complexity is a problem to overcome in instances like the one described.
