Adding seaweed to cattle feed could reduce methane production by 70%

mindblowingscience:

If we add dried seaweed to 2 percent of sheep and cattle feed, we could cut methane emissions by more than 70 percent, scientists have found.

With livestock responsible for 44 percent of all human-caused methane – a gas that has 36 times the global warming potential of CO2 – this could cut a huge chunk of the 3.1 gigatonnes these animals release into the atmosphere each year in burps and farts.

To put that 3.1 gigatonnes of methane into perspective, the entire European Union releases just over that amount of CO2 each year.

And if we cut that 3.1 gigatonnes by 70 percent by adding seaweed to livestock feed, we’d be clearing 2.17 gigatonnes of methane released into the atmosphere by livestock every year.

That’s almost the amount of CO2 the entire country of India emits every year.
