This just seems like blatant greenwashing for the cattle industry. This article makes the claim in the headline that it's "carbon positive", but makes an incredibly weak case, even saying that a researcher "believes" that it's carbon positive. This is opposed to the glaringly obvious fact that cattle ranching is incredibly bad for climate change and deforestation:
However, one study revealed that cattle ranching has also been Colombia’s top contributor to illegal deforestation in recent years. Between 1985 and 2019, more than 3m hectares (7.4m acres) of the Amazon rainforest were cleared for pasture.
This is just another techie sounding idea to solve climate change without doing anything, which we'll all forget about in a few years time. Does anyone even remember the whole "rewilding" fad that was huge in England 6 years back??
