Feed additives don't change overall methane emissions much, and not at all near what's touted by grossly misleading stats
https://www.wired.com/story/carbon-neutral-cows-algae/
Thanks for sharing! I agree with your main point about overall emissions not changing too much since most of that reduction comes from feedlots already.
One small addition: the product that I originally linked is based on 3-nitrooxypropanol, a petrochemical-derived active ingredient, not from red algae (so there is probably a different calculation about production cost and CO2 impact than growing, processing and transporting red algae on a large scale).
