"Research suggest that adding 2% of seaweed Asparagopsis taxiformis to the diet can reduce methane emissions by over 99%. (Machado et al 2015, Kinley et al 2015 (same report). Yes, I know, if it sounds too good it probably is........and even I am generally cautious about anything that sounds almost too good to be true!
It seems Asparagopsis taxiforma is an invasive plant so having a good use for it would provide an incentive to harvest at least until it is under control. It is invading the Mediterranean area so whether it grows in the UK I do not know. Also from a commercial point of view cost could be an issue."
