One of the largest contributors to problems in our society in general has got to be the way we’re eating right now. There are people in Canada who crave things like watermelons, cantaloupe and pineapple even in the middle of winter. Clearly none of those things can be grown in either Canada or the US in January without being grown in a greenhouse, so typically those fruits and others are flown/trucked in from thousands of kilometres away.
The result is a vastly inefficient food cycle. Things are even poorly managed locally during the past few years. E. coli outbreaks, listeria, salmonella, etc. The solution? It may be vertical farming.
