A Canadian researcher at James Cook University in Queensland, Rob Kinley, has found the seaweed species Asparagopsis taxiformis reduced methane by 99% in a laboratory.
The seaweed species has a natural defence against predators in the ocean, and that mechanism has a direct relationship to the bug in the rumen of cows and sheep, says Kinley.
Livestock is one of NZ’s biggest climate change issues: the methane they emit makes up almost a third of the country’s greenhouse gas emissions.
