No. The concern is about the overall impact of the aquaculture required to scale this seaweed feed supplements production to have a meaningful impact on the methane production from livestock. If you ramp up seaweed production, and reduce methane, but the overall process (aquaculture, processing, distribution) produces anything but than a net negative in GHG emissions, then the only value of the process is greenwashing cattle ranching.

I am not hellbent on finding additional problems, the point is that a lab based solution doesn't solve the problem, and most of your comments have ignored the very real market realities. I would also wager that your opinions are not necessarily grounded in reality - I chatted with my brother, who was a pig farmer for nearly two decades and is still involved in agriculture in both farming and ranching, and my cousin who runs a very large ranch in Manitoba. Some of the concerns I brought up in my previous point about market pushback are summaries of the questions and concerns they raised, although they both thought it was really interesting because they are both especially interested in sustainable farming practices.

Switching gears because you moved the goalposts, nothing I have said has anything to do with starvation or hunger. Since you brought it up, it is almost absolutely certain that building technology that mitigates, partially or wholly, the environmental impact of cattle farms actually exacerbates world hunger. The simple reason that is that the labour and resources that go into producing meat for human consumption would produce significantly more human consumable calories if we shifted those to plant based alternatives (up to and including feeding people seaweed).
