A new study from researches at the University of Helsinki has found that dung beetles living in cow patties may reduce emissions of the key greenhouse gas emitted by cow manure – methane.
Cattle contribute to global warming by burping and farting large amounts of greenhouse gases. Scientists have attempted to reduce those emissions by adding garlic and oats to their diet. But the appropriately named dung beetle does it naturally.
Atte Penttilä, who was part of the study explains: “We believe that these beetles exert much of their impact by simply digging around in the dung. Methane is primarily born under anaerobic conditions, and the tunneling by beetles seems to aerate the pats. This will have a major impact on how carbon escapes from cow pats into the atmosphere.” Continue reading
