Colombia prepares to fight against Pablo Escobar's hippopotamuses

Colombia is preparing to combat the hippopotamuses of Pablo Escobar. They escaped from the drug lord's private zoo in 1993 and have since reproduced in ideal conditions. The authorities have long tried to control their population, but without success. Last year, hippos were recognized as an invasive species that harms the ecology. Now they will be actively sterilized and sold to foreign zoos.
