2. Vertical Farming
It will take just 150 buildings to feed the entire city of New York per year.
Even better, these farms would be self-sustaining and LEED certified.
The cost would be around $20 million per building, but could feed over 50,000 people.
The benefits of Vertical Farming clearly outweigh the drawbacks:
Access to year-round fresh fruits and vegetables
Organically Grown: no herbicides, pesticides, or fertilizers
More food using less land
