Key Concepts

  • Farming is ruining the environment, and not enough arable land remains to feed a projected 9.5 billion people by 2050.
  • Growing food in glass high-rises could drastically reduce fossil-fuel emissions and recycle city wastewater that now pollutes waterways.
  • A one-square-block farm 30 stories high could yield as much food as 2,400 outdoor acres, with less subsequent spoilage.
  • Existing hydroponic greenhouses provide a basis for prototype vertical farms now being considered by urban planners in cities worldwide.
