You could do this with a little math yourself to see if it's a real concern instead of what appears to be trying to discount the accopmplishment. Per Google a cow eats about 2% of its body weight. A cow weighs between 1000- 1800 lbs and emits 70kg to 120kg of methan each year. Methane is 20 times more effective as a greenhouse gas so call in 2000 kg C02 equivalent each year. Are cow will eat 20-36 lbs per day so let's call it 12kg * 365 which is roughly 4400kg/year
So at 2% of their diet that's about 88kg of seaweed or about 200lbs
A truck emits 100g /km tonne of CO2 so a 1000km drive to Vancouver presuming we can ship something back would be 10kg of CO2
So 2000kg of CO2 saved for 10kg of transport. Presuming the co2 emitted seaweed farming vs hay farming is equal.
