The case pertains to a lawsuit against the Colombian government, which is considering killing or sterilising the offspring of hippos once kept as pets by notorious drug kingpin Pablo Escobar. Since the 1980s, the hippo population in the late drug lord’s ranch now number 65-80. Colombian authorities see them as pests, and anticipate violent encounters with humans soon. The Animal Legal Defence Fund in the US thinks otherwise. Its request to grant ‘legal personhood’ to the hippos was allowed – by the US court – earlier this month, even though it won’t apply in Colombia. Sovereign issues aside, we still say hippo hippo hurray!
