Two sides to every coin...

One of the main arguments of those opposing GM crops is that their seeds might contaminate nearby fields with possibly harmful results.  To meet this argument, GM producers have come up with "suicide" or "terminator" seeds, which are designed to be planted, grow, crop and then die off without producing any further seeds.  Good idea?  Well, no, it would seem, because this of course would mean that farmers would be forced to buy new seed every year from the GM producers. So you're damned if you do, and damned if you don't!
