Last week US regulators approved the sale of lab grown chicken. That means it's meat grown from real chicken cells, but never was part of a live animal. Tastes like chicken without having been one. So there's no beaks, no feathers and no slaughtering, but you have to be ok eating something made in a lab. It'll still be years until it's actually on store shelves. Fish made that way is also being developed and then there will be beef. But would you buy it? Can you see the case for it?
