When you make meat in labs, why would you need cows. For milk, I guess...but I'm sure scientists will figure out a way to make milk like they've discovered a way to make meat in a lab.
And it's not only red meat. Pretty much all meat including chicken & pork can be made in a lab.
They're calling it "Cellular Meat". And it sounds delightful! I'm obviously being sarcastic. REALLY? I think I'll stick with the old fashioned way. But as the animal rights crew grows so do ideas like this.
