Food Systems: Indoor Ag?

The possibilities of urban and vertical agriculture are fascinating. These systems have the potential to rewrite the rules about what crops are grown where. They have the potential to solve transportation, water, and land availability issues.

A large downside? These systems are truly factory farming and could require large capital investment. That could be a big barrier for entry-levels farms.  

Also! The likelihood these systems are more vulnerable to catastrophic failure from pest infestations and pathogenic pandemics.
