"You've seen something as fresh and tasty as meat, but inorganically [grown]..." - Cmd Riker

In the near future, it will be possible to grow meat. The practice promises to be more humane, sustainable, and efficient than conventional meats, with one analysis suggesting it would:

• use 35 to 60 percent less energy
• emit 80 to 95 percent less greenhouse gas
• use around 98 percent less land.

In a world where nearly half of all crop production is used to feed livestock, a move towards artificial meat may be inevitable.
