(This post originally appeared on Sustainablog on 8/1/11) In the debate about GMO crops, the “threat of genetic contamination” is often raised as a reason to reject the technology. Is this threat real? Does it justify acts of vandalism? Could it lead to the “End of Organics“? Is it actually an over-blown issue? To answer these questions it is necessary to put this issue in the context of basic plant biology. What We Are Talking About Is Really Just “Plant Sex” “Genetic Contamination” is an emotional term which obscures the fact that the underlying biological process in question is quite normal, natural and highly necessary.
