Reply #12: Betting on horses at the track

[Confusious]

brings in a much better return then working a job, but its not very stable.

There are 5 Billion people on this planet. Right now, return on investment is not the pressing problem. How to fill all those bellies when they growl is. Crop rotation and fallow fields works, but it doesn't produce the yields that chemical fertilizers do. Case in point Europe in the mid-19th century which you didn't even touch. Don't let reality intrude on a dream world huh?

As far as distribution system, WTF does that have to do with chemical fertilizers or sustainable farming?
