By dramatically reducing methane emissions Mr Elsom's work is strengthening the sustainability of livestock industries, slowing global warming and potentially changing the course of our planet's future.
Sea Forest's supplement contains bioactive compounds that stop methane production in the animal's gut.
Adding just 0.2 per cent of the supplement to livestock feed can reduce the methane emissions of cows and sheep by up to 90 per cent, while increasing productivity.
