Letters: GM crops `bias'

Sir: I have just driven down the A1 for 100 miles and have enjoyed the bright spring flowers which decorate the verges most of the way. These are nearly all bright yellow, and can be identified as oilseed rape. These flowers were never planted there, but found their way there, borne on the wind or by birds. Can anyone really believe that GM plants won't be carpeting the verges in a few years' time?
