Farming is the oldest industry out there, but it's one that's far from being perfect. Some parts of the world suffer from major cases of over-farming, whereas other places can't get enough. It's tricky trying to get the right balance between supply and demand when it comes to food, but with thanks to machine learning techniques, we may just be one step closer to achieving this. The world's population is steadily increasing, and in order to continue to feed everyone, farming techniques need to become more efficient and farmers smarter. One new technique that has been developed to tackle this problem is vertical farming.
