Reply #87: In time it would feed the world

[lunatica]

When every country can invest in these farms the need for fossil fuels will fall. It will happen with every vertical farm and become more widespread as the farms proliferate. Produce will not need to be trucked across the country because your city can have any number of these where you can go to the built in store and buy fresh produce every day.
Things can be grown until they're ripe and then harvested and sold in the ground level supermarket right away. With the ability to control temperature no matter what the weather is like outside these vertical farms food can be grown all year. And as it's seen to have a wide range of effects on other problems we have, such as the need for fossil fuels for transporting.

And each vertical farm would have to have an army of people to work in it, from actual agriculture employees to start seedling, grow, maintain and harvest the food, to engineers maintaining the machinery, electricians, hydroponic specialists, janitorial services and clerks selling the food to the community at the local supermarket.
