rescue cows greeting new comers at a sanctuary.

[Catherine]

There are a lot more farm animal sanctuaries now. Animals that somehow escape from factory farming end up in sanctuaries. 
Maybe some day that is all that there will be. We will shift away from this massive exploitation of animals for food. 

If they can perfect growing "meat" from a few cow cells then a few cows would be needed to give tissue samples. They could live happy lives unharmed. The grown "meat" would satisfy dietary requirements. It would be a kinder gentler future for all of us.
