A Sprinkle of Seaweed can Eliminate Greenhouse Gas Emissions from Cattle

One could say that we have a beef with the rising amount of methane (CH4) in the atmosphere: although this powerful greenhouse gas breaks down much faster than carbon dioxide, it traps 86 times more heat than CO2 over a 20-year span. Human activity has been the chief source of the increase in modern CH4 levels, having increased by about 150 percent since 1750, with about half of all human-generated methane coming from our livestock -- particularly from the planet's 1.5 billion cows. However, a new study has found that spicing a cow's feed with simple seaweed can cut a burping bovine's methane production by up to 99 percent.
