The eggs of the endangered sea turtle are considered a delicacy and an aphrodisiac, making them an expensive commodity on the black market. To catch poachers who steal sea turtle eggs, a conservation nonprofit is planting GPS-implanted eggs along with real eggs. That way, when poachers take eggs from a sea turtle’s nest, the nonprofit can monitor the movements of poachers and stop them in their tracks. The data that the nonprofit collects could also be shared with governments to aid enforcement of anti-poaching laws, particularly if the trackers show that the eggs are crossing borders and violating international treaties.
