By the year 2050, nearly 80% of the earth’s population will reside in urban centres. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. Vertical Farms make the most sense for cities.

Vertical Farming Explained, with Dickson Despommier

Dickson Despommier: Vertical Farming | BIG IDEAS | GOOD

TEDxWindyCity -- Dickson Despommier -- The Vertical Farm

"The vertical farm is a world-changing innovation whose time has come. Dickson Despommier's visionary book provides a blueprint for securing the world's food supply and at the same time solving one of the gravest environmental crises facing us today."--Sting

Imagine a world where every town has their own local food source, grown in the safest way possible, where no drop of water or particle of light is wasted, and where a simple elevator ride can transport you to nature's grocery store - imagine the world of the vertical farm.

Vertical farms will allow us to:

- Grow food 24 hours a day, 365 days a year

- Protect crops from unpredictable and harmful weather

- Re-use water collected from the indoor environment

- Provide jobs for residents

- Eliminate use of pesticides, fertilisers, or herbicides

- Drastically reduce dependence on fossil fuels

- Prevent crop loss due to shipping or storage

- Stop agricultural runoff
