Marine biologist Elvira Alvarado, hailed as "the mother of Colombian corals," is leading efforts to rescue endangered Caribbean reefs. At 70, she employs in-vitro fertilization to reproduce coral, combating the devastating effects of disease, pollution, and rising ocean temperatures. Despite the challenges, Alvarado and her team are focused on growing hardier coral varieties, aiming to regenerate reefs faster than they die and ensure their survival for future generations.
