Vertical farming is making progress, but not profits

Vertical farming is a potential solution for adapting agriculture to climate change, and to the growing food instability crisis. But it faces a profitability challenge, with several companies facing layoffs and bankruptcies. High energy costs and the need for substantial investments limit the financial viability of growing staples like potatoes and carrots. Instead, startups like the Paris-based Jungle produce premium crops like herbs and flowers that can be sold at a high markup.
