π Passage A β The Rise of Vertical Farming
As urban populations grow and arable land becomes scarce, vertical farming has emerged as a promising solution. This method involves cultivating crops in stacked layers, often within controlled indoor environments. By using hydroponics and LED lighting, vertical farms can produce food year-round with minimal water and land usage. Cities like Tokyo and New York have adopted vertical farming to reduce food miles and improve sustainability.
Despite its advantages, vertical farming faces challenges. High energy costs, technical complexity, and limited crop variety are common concerns. Critics argue that the technology is not yet scalable for staple crops like wheat or rice. However, ongoing research and investment are driving innovation, and proponents believe vertical farming could play a key role in future food security.
