Climate advocates say we must eat less meat and eliminate domestic cattle and sheep herds – this will then eliminate their methane emissions, that come from their stomachs.
However, this study in Nature finds that areas where domestic animals are eliminated may be quickly replaced by native, wild herbivore populations. There may be little or no net reduction in methane emissions.
The authors say that necessary data to understand this accurately may not be available and is, in some cases, based on estimates.
