"By the year 2050, nearly 80% of the earth’s population will reside in urban centres. The human population will increase by about 3 billion people during the interim. If we don’t learn how to [vertical farm] soon, these will become horrible places."
According the UN, the amount of arable land per person decreased from about an acre in 1970 to roughly half an acre in 2000 and is projected to decline to about a third of an acre by 2050.
There will simply not be enough farmland to feed us.
Vertical farming also uses a fraction of the water land farming does. Countries that are "water challenged" will implement this type of farming in the near future says most scientists.
