But, also, the fact that not all cattle (nor goats) are domesticated, nor will all of them wind up as meat for human consumption.sooner or later.
@gnotiall’s graphic and post is about meat consumption; @LSLGuy 's graphic and post is about the total weight of mammals on the planet. The two are somewhat related, but it shouldn’t be too surprising if they don’t tell exactly the same story.
Understood, but they seem to tell a fairly different story regarding pigs and cows.
The cite I found is on-point to the issue of meat consumption.
The XKCD cite is not.
It could be said more people on the planet eat goat meat than pork or beef, I guess. I mean those two meats are against some religious restrictions, and goats are common. But those of us that eat beef eat a lot more meat than many others on Earth.
That proposition I could certainly believe. e.g.: “More people will eat at least one serving of goat this year than at least one serving of beef.”
Yeah, that sounds more believable, doesnt it?
In the 1950s, there was a fad sweeping the nation where couples would compete to see who could poison the most pigeons in parks. Nobody wants to eat a bird that’s been poisoned.
No wonder the world seems so out of tune these days.
No it doesn’t! It tastes much more like lamb than beef, and really, it has a somewhat distinctive flavor of its own. Also, the goat I’ve had, admittedly kid, not adult goat, wasn’t tough at all.
(I’ve had goat meat from two sources. One is a tourist farm, where you can feed the baby animals and also buy the meat. I’ve bought frozen kid from them and roasted it. The other is an Indian restaurant that had small bits of highly seasoned stewed goat in some of the dishes. That could have been almost any meat. It could have been pigeon.)
Goat is a big part of the Indian/Pakistani dinner buffet that I go to. It’s usually stewed, and reasonably tender. It tastes just like lamb (not surprisingly).
Okay, I know “ghost” = goat, but what is “right” a swypo for? 
I refer to it as ‘goaty’ 
. Which sounds like I’m making a joke, but I’m not. Goat milk tastes goaty, goat-milk cheese tastes goaty and unsurprisingly goat meat tastes goaty. I do find it similar to lamb (which I really like and prefer), but as you say distinct. Though I don’t dislike the flavor, the more intensely goaty it is generally the less palatable I find it. Just like mutton is an acquired taste over lamb that I’ve never acquired.
Actually now that I think of it, I think I prefer milder-flavored proteins very generally. I mean I do prefer turkey thigh over turkey breast and like I said above I’m fond of lamb. But I always prefer milder white fish to stronger-flavored, fattier, oilier fish. I prefer pork to beef. Beef to most game meat preparations I’ve tried (I’ve had individual exceptions). Roasted meat to smoked meat.
Goat is fine, overall. I’ve had rank, tough, unpleasantly greasy goat and a more delicate-flavored, very pleasant goat. I think that variability might be baked in to the inconsistency of what mom and pop restaurants can source in the United States, because it has been in either goat tacos or in a goat birria in small taquerias.
Tough
(And my phone just “corrected” that to “right” again. I had to carefully fix it.)
Your phone doesn’t seem to be as fond of goat as you are. 
My phone doesn’t eat meat at all.
