Why is it? Sorry to be so thick there, gregorach! I honestly have missed this one.
Continued population growth is obviously a non-starter, we're both agreed on that. Where we disagree is on how best to maximise (a) the sustainable human population, and (b) the aggregate carrying capacity and biodiversity of the environment. I'm certainly
not arguing that we can have unlimited population growth indefinitely, no matter
what we do - even the Soylent Green option can't achieve that. My
personal solution to my portion of the population problem is simple: don't breed. I'll wager
that decision has contributed more to reducing my environmental footprint than veganism ever would, but I'm not about to start telling other people what they should do...

Which is totally
not what I'm talking about here. Not all meat production is equal. I completely agree that we shouldn't be expanding meat production, especially not at the expense of using good arable land which could be put to better uses. I'm just saying that we shouldn't necessarily completely eliminate the portion of meat production which
doesn't use good arable land. I completely agree that the "western lifestyle" normalises the consumption of
far too much meat, I'm just not convinced that going to the opposite extreme is the necessarily
always best option.

The whole point of my argument is that, in
some circumstances, your approach does
not sustain "far more people" - it sustains
fewer people, and lowers biodiversity into the bargain. There is no one easy, perfect answer which is applicable in all circumstances.
Now, if you want to make an
ethical argument for veganism, that's entirely fine and I'm not really interested in arguing about it. My entire point in this thread is that I'm profoundly unconvinced about universal applicability of the
practical argument you're advancing.
