I take exception to that: My family raises cattle for a large part of our income. ALL of the cows and bulls have names. They are all treated very well with plenty of green pasture to roam and eat in. They all come when we call them to eat, and we know which ones need to be apart from others so they'll be able to not fight over the hay. For the ones that go to auction/slaughter, they are treated with respect and amazing care. Stressed cattle do not fatten up and do not give you the best return of investment. It's in everyone's best interest to keep the cattle happy and healthy. We do not have penned up cows that stand there and eat, like a lot of those "factory farms" you see in the PETA videos. Much of that exists in California where resources are very limited, and state government agencies' oversight forces them to use those obscene methods to "raise" cattle. Here in Texas, land is cheap, water is more plentiful than California, and the cows are happier.
As for the OP's topic, I agree that there should be other options than leather. My last car was a Mercedes that had the MB-Tex vinyl. It was amazingly resilient! As for my Model S, I got the textile option because I didn't want to have to mess with the maintenance of leather.
