Cleaning up cow burps to combat global warming
Briefly

Livestock are important for food but contribute 14.5% of global greenhouse gas emissions, mainly methane. Research explores breeding low-methane livestock and altering gut microbes to reduce emissions significantly.
Methane from livestock has a significant environmental cost, with almost 40% of their global warming potential attributed to methane. Tackling methane now can swiftly impact global warming due to its short lifespan.
