A US military agency is investing $100m in genetic extinction technologies that could wipe out malarial mosquitoes, invasive rodents or other species, emails released under freedom of information rules show.
The documents suggest that the US’s secretive Defense Advanced Research Projects Agency (Darpa) has become the world’s largest funder of “gene drive” research and will raise tensions ahead of a UN expert committee meeting in Montreal beginning on Tuesday.
The UN Convention on Biological Diversity (CBD) is debating whether to impose a moratorium on the gene research next year and several southern countries fear a possible military application.
UN diplomats confirmed that the new email release would worsen the “bad name” of gene drives in some circles. “Many countries [will] have concerns when this technology comes from Darpa, a US military science agency,” one said.
The use of genetic extinction technologies in bioweapons is the stuff of nightmares, but known research is focused entirely on pest control and eradication.
Cutting-edge gene editing tools such as Crispr-Cas9 work by using a synthetic ribonucleic acid (RNA) to cut into DNA strands and then insert, alter or remove targeted traits. These might, for example, distort the sex-ratio of mosquitoes to effectively wipe out malarial populations.
Some UN experts, though, worry about unintended consequences. One told the Guardian: “You may be able to remove viruses or the entire mosquito population, but that may also have downstream ecological effects on species that depend on them.”
“My main worry,” he added, “is that we do something irreversible to the environment, despite our good intentions, before we fully appreciate the way that this technology will work.”
