New farming way that generate millions of Rands

Vertical farming practiced on a large scale in urban centers has great potential to:

1. supply enough food in a sustainable fashion to comfortably feed all of humankind for the foreseeable future;

2. allow large tracts of land to revert to the natural landscape restoring ecosystem functions and services;

3. safely and efficiently use the organic portion of human and agricultural waste to produce energy through methane generation, and at the same time significantly reduce populations of vermin (e.g., rats, cockroaches);

4. remediate black water creating a much needed new strategy for the conservation of drinking water;

5. take advantage of abandoned and unused urban spaces;

6. break the transmission cycle of agents of disease associated with a fecally-contaminated environment;

7. allow year-round food production without loss of yields due to climate change or weather-related events;

8. eliminate the need for large-scale use of pesticides and herbicides;

9. provide a major new role for agrochemical industries (i.e., designing and producing safe, chemically-defined diets for a wide variety of commercially viable plant species;

10. create an environment that encourages sustainable urban life, promoting a state of good health for all those
