The parents comment certainly is accurate for most staples, cereals, and even meat (raised on corn) but entirely misses the need for more fresh veggies and leafy greens in the US. In the states it generally costs more to buy food made with fresh vegetables. That’s where indoor and vertical ag shines. Many developed countries have plenty of empty calories. Too many. Indoor Ag provides an opportunity to provide scale and freshness to a number of non-grain foods, with less pesticides and preservatives. I hope the field is successful at that goal.
