It is expected that human population may reach 9 billion till the year of 2050, among which 80 percent people will be residing in cities. This planet will not have sufficient places for farming due to over-population. So we will have to find out a solution that will save this planet.
Other than oxygen and water, there is one more essential thing that people need to stay alive is food. In order to farm food, people need land which will be filled-up due to over-population, and they may not want to use forests land by eliminating long trees, because it may cause more damage to this planet. So it will be a big challenge to farm good quality food for 9 billion people in earth. Vertical farming is such an innovation that can solve this big problem.
Vertical farming is a kind of process which helps producing food in vertically stacked layers like in a skyscraper. They practiced vertical farming in warehouse, or shipping container. It is done by using indoor farming technique and controlled-environment agriculture technology. All environmental factors are controlled in this place. Less space will be occupied by vertical farming, and it may be capable to farm almost 1000 times more food on the same area of land.
