Scientists warn that a rapidly growing population of hippopotamuses that were introduced to Colombia decades ago by drug kingpin Pablo Escobar should be culled to preserve the local ecosystem, according to a study published this month. Researchers warned in the study, published in the journal Biological Conservation, that hippos, the "largest invasive animal" in the world, are likely to colonize habitats around the country with serious environmental impact.
