Notes on solutions: In the subdivision Euryarchaeota, uncultivated organisms in deep-sea marine sediments remove methane via anaerobic oxidation of methane stored in these sediments: methanotrophs can also convert methane  – see https://www.nature.com/articles/s41558-020-0736-x

The type of animal feed is a crucial factor in controlling the amounts of methane produced via enteric fermentation animals. AgResearch New Zealand is researching ways this can be reduced.
