A 2016 study that claims feeding cows small amounts of seaweed along with their normal diet of grass can reduce methane emissions by up to 99 per cent.

The study, by a team of researchers at James Cook University in Queensland, Australia, found in live trials with sheep that recorded methane levels fell between 50 – 70 per cent when they ate a diet including 2 per cent seaweed.

The Australian study was originally based on the experience of a Canadian farmer who realised that his cattle that ate washed up seaweed were healthier and produced “rip roaring heats” with longer mating cycles than those that did not.
