Cows in world := 1,000,000,000

Seaweed per day per cow := 0.085kg

Seaweed per year per cow := 31.025kg

Seaweed per year for cow population := 31,025,000,000kgs

Global seaweed production := 6,350,293,180kgs

So, we'd need to increase seaweed production by 5 times. We would then need to distribute this from the largest producers (China, Japan, Korea) the countries that consume the most (Europe, US). This isn't a problem that can be solved by mandated changes in a matter of years, and I have no idea what the CO2 output would be for this sort of production and shipping.
