Vertical Farms!
This is an amazing idea. Just think, cities in any climate zone would have the ability to grow enough fresh produce year-round to sustain their community without having to import foods. Think of how this could affect the environment…less energy for transportation, the ability to recapture runoff and greywater for use time and again, and a chance for decimated farmland to heal itself and potentially return to forested land. I really hope to see these begin to pop up within a decade.

Now if only we could convince people that it’s inefficient and environmentally unsound to continue using animals as a food source.
