You are half right about that. It also matters how these gases are released. Intensive cattle farming involves a lot of CO2 and methane that has more to do with supply chain of the food for the animals than it has to do with the animals themselves. Think soil erosion due to tilling (which emits massive amounts of C02 & methane), fertilizers, pesticides, etc. needed to compensate for that. Transporting of the animal food and the rest of the supply chain. And getting rid of the excrement and methane.

Compare that with regenerative farming where if done right, the cattle actually captures more carbon in the soil than is released as co2 or methane. Even just having animals not taking a leak where they dump their manure makes a difference. Amonia is nasty and gets created when you mix the two. That's why cattle farms smell so nasty: it's the urine and manure mixing when they shouldn't.

Same steak but completely different from a sustainability point of view. Expensive but tasty. Might actually scale if farmers were incentivized to try this. There's no shortage of land to restore.

Feeding cattle seaweed might help a little. But maybe let's not intensively farm oceans to feed land animals. That sounds like a net loss.
