Scientists in Denmark, the US and Canada have all been working on producing a genetically-engineered plant whose flowers will come up red instead of white in the presence of underground explosives. The idea, of course, is that you can use them to to test for the presence of landmines by dropping the seeds from the air and seeing what colour the flowers are when they come up.
Apart from the benefits if the technology works (and the rampant symbolism), this is the kind of project that the genetic engineers needed to come up with at the start of the technology to help sell it to the public. It would take a very hard person, however suspicious they were of science, to oppose a cheap new mine-detection technology.
Instead, of course, despite all the publicity about how GM products were going to end third-world hunger, reinvigorate medicine and who knows what else, the first major products were herbicide-resistent crops, allowing farmers to use even more toxic chemicals in the quest for ever-more intensive crop production. Personally I think that most of the opposition to GM food is incoherent, illogical and based entirely on prejudice, but I still can’t feel very positive about Round-up Ready soybeans.
