Question

Most people think that crops need to be grown outdoors. But what if crops could be grown without sunlight?
Researchers in the Netherlands think this might be possible. They believe that the perfect crop field could be grown inside of a windowless building. It would have carefully controlled light, temperature, humidity, and air quality. With this invention, crops would no longer be at the mercy of unpredictable weather or disease. Farms could be established in the middle of a city or a desert. Supporters say that these indoor farms could be the answer to the world's food problems.
