The man in charge of deporting Pablo Escobar's 'cocaine hippos' explains how he plans to fly 70 of them across the world

• Authorities plan to relocate 70 of the hippos living wild in Colombia, but it's not an easy task.
• Since hippos are large, aggressive, and have very tough skin, sedation requires a team effort.
• Hippos that can't be moved will likely be sterilized or culled, since they threaten the ecosystem.

Colombian authorities have decided to deport at least 70 of Pablo Escobar's "cocaine hippos" to zoos in other countries.
