Pablo Escobar's 'Cocaine Hippos' May Be Restoring Colombia's Ecosystem

Colombian drug lord Pablo Escobar left a legacy of criminal offense and violence in his region ― but his most lasting impact might be on the ecosystem.

Properly, not Escobar specifically, but a team of nearly 80 hippos descended from the 4 he owned that were set free of charge just after his death in 1993.

While the so-called “cocaine hippos” have been accused of wreaking havoc on the nearby ecosystem, a new analyze implies the invasive animals may also “restore ecological functions” missing for thousands of decades due to “human-driven extinctions.”

In other words, it seems that huge herbivores like the hippos in Colombia are actively playing a biological purpose similar to that of mammoths, big sloths and giant wombats throughout the Late Pleistocene time period about 116,000 to 12,000 decades back.

Study co-creator John Rowan advised the Guardian that Escobar’s feral hippos have a food plan and body measurement like people of the extinct large llamas that employed to stay in the region, though they share a identical dimension and semiaquatic habitat with a further extinct mammal identified as the notoungulates.

“So, though hippos really don’t flawlessly substitute any a single extinct species, they restore elements of critical ecologies throughout many species,” said Rowan, a Darwin fellow in organismic and evolutionary biology at the University of Massachusetts Amherst.

The review goes towards the typical destructive watch of invasive species.

For case in point, Escobar’s hippos have been accused of polluting lakes with their feces. But review co-creator Erick Lundgren pointed out to Gizmodo that hippo poop “plays a keystone role in boosting fishery productivity” in Africa, so it’s possible it’s not all bad.

Rowan acknowledged that the new report may perhaps result in some controversy in biological circles, but hopes it encourages individuals to take into account extensive-expression effects when assessing the impact of invasive species on a unique ecosystem.

“Hopefully it ignites a discussion on entrenched sights in conservation biology and encourages folks to ‘take the extended view’ when wondering about biodiversity’s earlier, current, and foreseeable future,” he advised Newsweek. “All we require is an open head and a tiny creative imagination.”

The study seems in the most recent issue of Proceedings of the Countrywide Academy of Science.
