A positive idea for us to use now to grow healthy local food in cities...
I was inspired tonight by a different perspective on producing our food: the
vertical farm!

Producing food in stacked greenhouses (or possibly better designs that allow
us to use more sunlight), in cities, to grow our food instead of ship if
from who knows where. Totally hydroponic, no dirt required, add a few
nutrients to water that circulates and is therefore conserved. Very low
technology, but the cost of doing this in cities is limited by the price of
real estate. There are practical solutions out there.
