@everyone in particular

Just seems like a bad idea based on the reproduction rates of apex predators. Apex organisms generally take the most in terms of ecological resources to generate and they spawn few offspring. Importantly, the food chain "expects" them to contribute a certain feedback. In their natural system they are generally not shaped by predation. If a trendy, whimsical "why not lions" eatery movement arises, lions are much less "apex" all of a sudden and the Lion part of a massively complex system has a seriously unexpected feedback. The influence of the lion part sends a good wobble into the ecosystem that will shake the general lay of the land (including humans that can't buy their way into a separate existence from their land base; *cough* Africa *cough*) until things equalize into a new pattern. Keep in mind that the land doesn't give a hoot about the way we think things should work.
God forbid it becomes a foodie trend of the western world. Lions would go the way of tuna. (p.s. mind your sushi choices.)

But don't worry - technology will save us...
Lions in battery cages, optimally fed and bred to increase tender lioney muscle parts to serve your taco and your entitled face hole.

FYI, I've been drinking.
I love you all.

Those scream "giant passive cooler" to me. Those are root cellars not bunkers! Classic weapons (spawn of) into plowshares situation. Unplug your refrigerators Albania wooo!
