Vertical Farms - amazing idea

Producing crops closer to the consumers and using efficient techniques will cut down on wasted water and other resources used for farming. Dickson Despommier at Columbia University in New York City stated that 80 percent of the land available for farming is already being used and to feed more people by 2050 we will have to produce crops in farms in Skyscrapers. Solar powered lighting system will be used to grow the crops, and there will be provisions to recycle water and waste by natural means. Crops will be safe from flood as well as drought and required amount of irrigation could be provided.
