Conservation demands safe gene drive

Interest in developing gene drive systems to control invasive species is growing,with new zealand reportedly considering the nascent technology as a way to locally eliminate the mammalian pests that threaten its unique flora and fauna. if gene drives successfully eradicated these invasive populations,many would rejoice,but what are the possible consequences? here,we explore the risk of accidental spread posed by self-propagating gene drive technologies,highlight new gene drive designs that might achieve better outcomes,and explain why we need open and international discussions concerning a technology that could have global ramifications. © 2017 esvelt,gemmell.
