With traditional farmland threatened by climate change, cities are turning inward to grow food. Vertical farms, using 95% less water than traditional agriculture and zero pesticides, are becoming the primary source of fresh produce for many urban centers. These facilities are often integrated directly into residential and commercial buildings.

The key to the success of urban farming is LED technology and nutrient recycling. By using precise wavelengths of light, farmers can 'hack' plant growth to maximize yield and nutritional content. Waste from the city is processed into organic fertilizer, creating a closed-loop system that reduces the carbon footprint of food transportation.

The next challenge is growing calorie-dense staples like wheat and rice in these environments. While leafy greens are easy, the energy requirements for grains are currently too high for vertical systems. Researchers are working on dwarf varieties of these crops specifically designed for indoor environments...
