>It takes a cow a lot longer to reach slaughter weight eating grass, so even if they're belching less during that time, it's a long enough time that it may be a wash, or even worse. This would still mean the cows live shorter lives and fart more intensely in that time. So that would destroy a headcount comparison with previous levels of wildlife, since basically now you're comparing one life of a bison with hundreds of cows living in it's lifespan.
