With less available land and more people to feed each year, we have a real problem on our hands, whether or not we all choose to acknowledge it. However, some people are already considering ways to fix it, and one of the most viable solutions is to build massive vertical farms that require no soil, use water efficiently, and replace the sun with LED lighting to grow fresh produce.

The biggest vertical farm in the world is currently under construction in New Jersey, and it will produce some 2 million pounds of lettuce and other leafy greens per year once it's completed.

AeroFarms already operates one such farm and the results have been extraordinary. The facility is able to grow vegetables indoors without requiring fertile soil or any sunlight at all. These crops consume less water as well, since the system uses a root-misting nutrition and oxygenation procedure that needs 95% less water than a regular field.
