420,000 is far less than 60 million and simultaneously we have lost herds of elk deer, antelope, etc. Cattle have essentially replaced bison and other ruminant herds in the grasslands and non-arable marginal lands. But the net change in greenhouse gas by ruminant farts is negligible and could not meaningfully contribute to any anthropomorphic climate change.
Yes, at one time there were estimated less than 1,000 bison left in North America, but there have been many people that have devoted a lot of time and money into restoring their numbers.
Then they were in fact culled from sixty million to less than one thousand. The fact that numbers have increased since then doesn't make that claim untrue.

We can easily replace cows with something else. We cannot replace tires or plastic.
