Will feeding cows seaweed help save the planet?

Seaweed could hold the key to cutting greenhouse gas emissions, one cow burp at a time. New research carried out in north Queensland could drastically reduce the impact the agricultural industry has on the global environment. Professor of aquaculture at James Cook University in Townsville, Rocky De Nys, has been working with the CSIRO studying the effects seaweed can have on cow's methane production. They discovered adding a small amount of dried seaweed to a cow's diet can reduce the amount of methane a cow produces by up to 99 per cent.
