Frankin-meat?

For you meat eaters and (non-meat eaters as well) out there, if you could eat meat that did not come from the killing or harm of any animal would you? What if that meat was grown in a lab? Scientists have for a couple of years new been working on growing meat in a test tube, sometimes called In-Vitro Meat or Cultured Meat. Think about the possibilities, no fears of mad cow or avian flu, or the environmental destruction from large scale agribusiness. The cruelty associated with raising animals for food would be eliminated. I know the idea might seem unsettling, but what is more unsettling, killing and dissecting animals to eat them or growing sheets of "meat" in a clean room free from disease, hormones, pesticides, cruelty?

Of course what will happen to farm animals if this catches on? Will the cow and the chicken go extinct?
