Singapore Builds First Vertical Farm

As more and more people inhabit the Earth, there is less and less arable land for agriculture. For Singapore, a small, crowded country that imports most of its food, increasing the amount of produce grown yearly would be beneficial, so they have developed vertical farming.

Vegetables are grown in multiple troughs, in twenty-seven foot tall, aluminum towers. Although more expensive now, the prices are expected to drop as the farm increases production.
