Unless we start farming seaweed not sure how we can feed all the cows we eat seaweed.

To produce feed that the cows enjoy, the researchers cut a small amount of red seaweed with cattle feed and molasses. You only need to add a little seaweed to the cows' regular food.

Yep and I guess if it is only California dairy cows then that wouldn't be a lot either. Time to think about farming seaweed :)

What’s also cool is that oceans sequester carbon in seaweed the same way forests sequester it in trees. So it’s a win-win to farm seaweed!

Earlier quoted context omitted.

A quick search suggests that in fact the 'vast majority' of the emissions are coming out the front, not the back: https://www.greenbiz.com/article/gassy-cows-facts-about-beef...

This makes me wonder if the major source shifts to the back after the treatment.

If the end result is less total emissions, then we've won.

IANA Biologist etc, but isn't the problem their gas emissions from the other end of the cow? Isn't this like some new tech eliminating all the carbon emissions from using the radio in a car, cool but not the problem?

Why are you downvoting this guy for asking something out of curiosity? He clearly says he's not an expert and he's asking for more info. Is everybody here a fucking knowitall retard?

Really interesting, and potentially highly relevant to New Zealand where our many cows and sheep make up about a third of our emissions. Since cows produce quite variable emissions it sounds quite credible that some out of the box thinking like feeding seaweed could actually work in cutting emissions.

> (https://www.landcareresearch.co.nz/science/greenhouse-gases/...): Measurements of methane emission rates on sheep and dairy cows have repeatedly shown that the variability of emissions between individual animals is large (e.g. for young sheep grazing the same pasture, emission rates varied from 9 to 35 g/day per sheep). While this variability may one day be exploited to reduce methane release by selecting for low-emitting animals, it is not well understood.
