In 2016, the national government announced the adoption of the programme Predator Free 2050, aiming to reverse biodiversity loss trends in the country. A few years have passed, and many academics and researchers are still sceptical about whether this goal is feasible. The main reason? The programme rejects one of the most promising invasive predator management tools – gene editing.
