Everyone wants to talk about GMs...(meanwhile, we're soaking in them)

What do farmers want?
More production for less input (higher yield).The "triple stack" (corn and soy requirement).Drought tolerance, water use efficiency.Nitrogen use efficiency (lower need for nitrogen).Disease and pest resistance (lower need for chemical inputs).Various "agronomic traits".

A growing middle class worldwide wants to eat the way Americans and
Europeans do.That would require more farmland than exists on the face of this planet....
....by a factor of about THREE.

Seed companies (and independent breeders worldwide) are responding to this by developing new, higher yield, lower input varieties.
....surely that's only part of the solution.

Almost NONE of what you see in the produce section of your supermarket occurs in nature.
It's ALL genetically modified.
