But it is also a high risk, high yield strategy. The high yield is great, the high risk not so much. It is heavily reliant on very few, very closely related varieties and pesticides. That's just a ticking clock until a fungus or something like it, attack these strains and the lack of genetic diversity leads to mass starvation.

There's also the very long term damage from chemical fertilizer, things like hard-pan.

Hardly. Part of the Green revolution was the heavy use of chemical pesticides which is horrible for the environment.
