New Zealand has a rat problem. The non-native rodent, which originally hitched a ride to the island on ships in the 13th century, has proliferated to such an extent that it is now partially responsible for the endangerment of many of New Zealand’s native species.* The kakapo, for example—a giant flightless parrot that is endemic to the island, and evolved without the threat of rats—nearly went extinct in 1960. Today, its population stands at 153.
To save the country’s birds, New Zealand has introduced an ambitious plan to eradicate its invasive predators. Predator Free 2050 will employ multiple techniques, including CRISPR, with a single end goal: to kill every last rat on the island.
