Way back when, farmers tended to grow different hybrids. They'd save seeds from the best, perhaps create their own variations, that kind of thing. The crops they grew tended to be subtly different (even within a species) from the crops their neighbours grew. If a bug figured out how to wipe out one person's crop, its trick might not work on the one next door, and so it's spread was limited. With everyone growing the same trademarked GMO species, if one goes, all are vulnerable.
That's just crops though, and as bad as the consequences might be, there are potential solutions.
Have any of you noticed how it's spread? How many here either are, or have eaten foods (primarily yogurt) with 'pre-biotic' or 'pro-biotic' bacterial cultures in them, aimed at whatever health benefits they're claiming? Lets take one in particular (nameless, although if you think 'Activ-', you're only short the last two letters). This one contains a proprietary (probably trademarked, if not patented) strain of bacteria designed to colonize your intestinal tract, most likely replacing at least a portion of whatever native fauna are already there. Think about it. Millions of people having the exact same strain of patented bacteria in their digestive system. No variations, no uniqueness. Should this specific strain prove vulnerable, would that mean every person whose guts have been invaded by this stuff is at risk?
It's good yogurt though.
