Population density is only the tip of the iceberg. The problem is that the land available for farming is limited, therefore the amount of food to feed people is finite. The seas provide some food.

Then there is the land able to be homes to people. That's finite, too.

True. And regardless of what people are arguing, continued population growth is unsustainable given those finite present and future resources. When I was in international relations grad school, we used to argue about the current and future coming resource wars...

Say hello to robotic “Vertical Farming.”

Coming soon to a neighborhood near you.

Coming next - nuts, fruits, and vegetables with no trees or plants.

Grow the apple - forget the tree!
