- what would happen to the economy in hot countries and cold countries.
- what would happen to countries that cannot or do not have farmable lands?
Methane is 8x worse than co2, and can be spotted from space better and better with each new environmental satellite.
In short, Farting is a byproduct of the normal work of a healthy cow stomach. If your cows don't fart, the cows are starving and will not grow (neither well, nor fast enough). The milk may even have a funny taste, so your career as farmer will not last. The entire job of a farmer is to raise the cattle to market grade as fast as is biologically possible
Giving cows a diet of seaweed is like trying to breed your baby on a whole diet of painkillers and aspirin.
Economically it does not make sense either, because this seaweed are a scarce valuable resource. They are difficult to regenerate, expensive to harvest, and are sold yet to industry for <bigger amount of money>.
But don't trust me. The best proof that it will not work is that in 20 years nothing came of it.
I wouldn't advice to put any of your money on this idea that was obviously dumb from the start: Seaweeds are sought for their antibiotic properties, and cows need its gut microbiome alive to break the cellulose into sugars. Sold the seaweed and buy steaks instead with the money.
What is the point to save a bit of CO2 here and there, when Ukraine, Sudan and Iran wars are sending us to the Carboniferous firing on all cylinders?
Arsonists detained in France, Spain and UK. In Calabria there are even reports of cats with flammable soaked rags tied to its tails, set on fire and released in the fields, they had found also candles lit among flammable rags, and delayed ignition devices [1]. This is everything except a natural disaster. Hybrid war. Don't look no further.

The biggest fire in France has most likely accidental root cause (https://fr.wikipedia.org/wiki/Feux_de_for%C3%AAt_de_2026_en_...)
China and Russia are doing relatively well at least. Except by Volgograd Oblast, that is boiling, and some Siberian activity below the expected average, most of Russia is quiet. China has less active wildfires than Spain.
And if you think that this, or the 652 wildfires in France and other 670 in Spain are bad, check the more than 30.000 critical-level wildfires active in Angola, Zambia and other African countries. African rainforest is a smoking disaster right now.
