Chasing hippos

Gina Serna is helping lead Colombia’s effort to sterilize the roughly 120 invasive hippos roaming the Magdalena River — hippos that were never supposed to be there at all. They were illegally imported decades ago by Pablo Escobar, the country’s most notorious drug lord. In many ways, it’s the perfect job for Serna. She dreamed of being a wildlife veterinarian since she was little. On the other hand, her career has a direct tie to the worst thing that’s ever happened to her.
