"If enough diversity is lost, the ability of crops to adapt and evolve will have been destroyed. We will not have to wait for the last wheat plant to shrivel up and die before wheat can be considered extinct. It will become extinct when it loses the ability to evolve and when neither its genetic defenses nor our chemicals are able to protect it. And that day might come quietly even as millions of acres of wheat blanket the earth."
