It’s CRISPR’s world, and we’re just living in it. The gene-editing technology, which has been likened to a genetic word processor, allows researchers to make specific changes ranging from tweaking a single DNA base pair to revising whole paragraphs of genetic information. Most of CRISPR’s media attention has focused on the vast improvements it could bring to medicine, such as fixing genetic diseases, curing cancer, speeding up vaccine development, andovercoming antibiotic resistance in disease-causing microbes. Less widely reported, but no less momentous, are the dramatic transformations that CRISPR will bring to nearly all aspects of farming. All that is needed for this new green revolution to take off is for regulators to get out of the way. Thanks to entirely...
