There is a lot to be said about the future sustainability of food, and there are a lot of really interesting initiatives like Soylent & Vite Ramen (basically Soylent "whole meal" ramen noodles). I think it was the Forks over Knives video that said we already produce enough food to feed 10 billion people, and we have less than 8 billion right now, but our food distribution system is where the problem lies (corruption, dictators, etc.).
We also have incredible growing technology these days. Up in Mass, we have Freight Farms, which is a whole greenhouse in a shipping container that you can buy as literally a turn-key farm:

Over in New York, we have Farm One, which is an indoor vertical hydroponic farming company that uses LED grow lamps:
GE has a 25,000 square foot facility using a similar technique:

The benefits are astounding:
1. Produces 10,000 heads of lettuce per day, regardless of the weather or season outside
2. Typical crop farms have a 50% yield (which means a 50% loss); this method reduces food waste to just 10%
3. Through temp/humidity/irrigation control, the indoor farm cuts water usage to just 1% of the water needed by an outdoor field
