  • It is projected that by 2050, about 80% of the world's population will live in cities.

  • For such economical reasons, Dickson Despommier,

  • professor of environmental health sciences and microbiology

  • at Columbia University in New York City,

  • believes that the food growth should come from the inside.

  • So, he has developed the idea of vertical farming.

  • But what exactly is vertical farming?

  • It is an architectural approach, based on two concepts:

  • the vertical development of buildings,

  • and the possibility of cultivating biological products from the inside.

  • Take a look.

  • My name is Dickson Despommier.

  • I teach at Columbia University's medical school and school of public health.

  • The world would be a much better place if we had vertical farming.

  • New York City, where I live, that's a big city right? Eight million people.

  • These eight million people consume food that it takes the state of Virginia in land mass to grow.

  • We have to find another way to farm.

  • And here's the other way to farm.

  • If you could think of stacking greenhouses on top of each other, that would be one way to envision it.

  • You know, the leaning, no, not the leaning tower of Pisa, forget about that.

  • Think about the hanging gardens of Babylon.

  • Here's my vision of what a vertical farm might look like.

  • My gold standard for this is the Apple store in New York City on 5th Avenue.

  • If you took that building,

  • and made it into a five story building...

  • Now in the building, you have multiple floors, of course.

  • And inside each floor you have multiple layers of crops.

  • Let's take some typical crops:

  • let's take tomatoes, strawberries, and turnips.

  • And you could grow a lawn of cabbage, a lawn of lettuce.

  • There's a seed sorting facility next door,

  • you've got people sitting there sorting out all of the seeds of the world coming in.

  • This one's good, this one's not so good.

  • You've got continuous planting at one end,

  • monitoring of growth in the middle.

  • And at the end of it, you've got people harvesting.

  • I mean, what you've done here is create a mini ecosystem.

  • My world will be ecologically balanced.

  • And it will be balanced because we've learned how to manufacture food

  • for ourselves in tall buildings within the cityscape.

  • We have learned to live within our means.

  • Life is good, life is good, life is good.

  • Thanks to hydroponics, these crops will be able to produce

  • a richer harvest as they are protected from atmospheric conditions and parasites.

  • The idea of vertical farming could be the solution

  • to many of the problems that we face today. Especially overpopulation and food shortages.

  • According to Dickson Despommier's estimates,

  • the large 30-story building will be able to feed up to 50,000 people every year.

  • Who would have ever thought that one day we could build skyscrapers that will feed us?

It is projected that by 2050, about 80% of the world's population will live in cities.
