The United States produces a huge amount of food. Cattle, chickens, turkey, salmon, and other types of meat. Other countries struggle to produce their own food. Struggle to feed their own populations.
What if, in the future, you could grow meat? No animal necessary, just the meat. Anyone who has been on a farm knows the quantities of feed necessary to grow an animal and the byproduct pollution produced. What if this could be done in a more “clean” environment?

I don’t know if this work work out or not. It sounds promising, however.
