Yeah so, the amount of meals is correct. But that's about it. I mean, I can't say about the taste, to each their own, but one kg of cow meat needs two dozen kg of grain.

That's about as inefficient as it gets.

As for the leather, the industry doesn't like products that last a decade, so it isn't actually using the leather in such a way. Industrial leather boots last a year tops.

Finally, pet food is made out of discarded cuts of meat, the uglies, etc. But also lots of cereals, and vegetables.

So we could really afford eating less meat. It isn't good for anything. Not for us, not for the other species (certainly not for the cows, that get often half assed butchered in a hasty way because of quotas and profit), and absolutely not for the ecosystem.

But I guess the taste is all that matters.
