The other day my girls were watching their shows and among the commercials was a feel good segment about a teacher in New York. The teacher had a program where he was teaching his students to grow their own gardens even in an urban environment. At one point it showed he had plants growing on a wall. That is an application that needs to be expanded upon.
Whether it be urban settings or stark settings where growing crops is near impossible a new generation of green houses should spring up. Large warehouse sized green houses where rather than depend on the mere square footage there would be wall after wall of double sided food production. The walls should also be raised and lowered as needed to tend to the plants and harvest the bounty. Fruits, vegetables, grains and nuts could be providing nutrition to the needy locals.
That is one idea.
