As the plane descended over the emerald cliffs and black sand beaches of Hawai’i, I felt both awe and responsibility settle in. Ahead lay ten days of volunteer service as a Mars Ambassador, partnering with PetFix to bring spay/neuter and preventive care to communities where veterinary resources are scarce. From the air, the islands appeared connected by ribbons of ocean, yet on the ground, each community faced its own barriers: distance, cost, and access to veterinary care.
