All this is arrayed against science, even if it’s science that could materially benefit the environment. Gluckman has urged that we open up to it, saying it’s doubtful sustainable farming can continue without gene editing. New Zealand has developed a potentially world-leading curb on greenhouse-gas emissions: a genetically selected rye grass that drastically reduces stock methane emissions. But our strict controls on GE have meant we’ve had to trial the grass in the US. Because it is gene-edited, a form of selective breeding, rather than…
