Every time someone plants a field of Roundup-Ready canola, the possibility it will cross pollinate with a wild, brassica type cousin increases, someday surely resulting in a Round-up resistant offspring. This should reduce the usefulness of Roundup over time which one might applaud if one happen to dislike it.
There is still hope, however, for the garden variety Roundup aficionado, as what may become uneconomical for mass agriculture may remain useful in the backyard.
