how many cows died for your leather seats ? ....

Leather is a by product, not the main product.

It hasn't always been that way. If you look how Oxo
cubes came about it was because meat was an unused
and wasted by-product of producing leather.

Much more likely to have been a byproduct of scraping
the remaining meat off the hide rather than all the meat
from the animal the hide came off.

Unusually wiki is no help about that.
