BBC News Magazine posted a story about Columbia’s hippo problem. It is an invasive species situation caused by the importation of these animals by infamous drug lord Pablo Escobar.
Ecologist Rebecca Lewison points out that hippos “aren't like crocodiles… they don't see a thing and instinctively want to kill it.” This explains why no one in Columbia has been killed or hurt so far. However, they’re one of Africa’s deadliest mammals, and are responsible for about 500 deaths per year worldwide (490 more than sharks and wolves). They are described in the article as a “time bomb,” and a lingering threat to the local population.
For various reasons, solutions to the problem are still unclear. One element hampering the implementation of a cull is the “floppy effect." Carlos Valderrama, a vet working to curb the problem, notes that Columbians “are more vulnerable than Africans because they see hippos as cuddly, 'floppy' animals.” This also means that the charismatic animals must be handled sensitively. Photos of the bloodied bodies of charismatic animals won't do wonders for PR (case in point: Danish zoos).
The article closes with a consideration of how these animals have been used in popular culture and have become a fleshy metaphor for “what's happened in Colombia in the last 20 years.”
It should also be noted: This American Life had a fascinating short report about a plan in the early 1900s to bring hippos to America as a new food source. This is an adaptation of a longer written account. Curiously (to my mind), no one on the program seems to find anything glaringly wrong with the plan.
