EMERGENCY! Colombia Has A Problem With Excess Hippos, Thanks To World's Richest Criminal - Pablo Escobar

For years, Pablo Escobar and the Medellin Cartel were notorious criminals who amassed a fortune in Colombia and were a scourge to their enemies.

Escobar’s Medellin Cartel were drug traffickers who took part in extortion and mass killing, amassing a fortune that made Escobar one of the world’s richest criminals.

Escobar’s style when dealing with authorities tended to be to bribe them or execute them. He was killed in 1993, but his life of luxury at the Hacienda Napoles ranch left a negative legacy for the Colombian environment.

At the height of his power in the 1980s, the drug lord brought four hippos to a private zoo at his estate, along with giraffes and elephants. After his death, while other animals were taken away, the hippos were deemed too difficult and remained at the property.

Now an estimated 80 hippopotamuses, perhaps more, live in the area around the Rio Magdalena, Colombia’s principal river.

The rapid growth of their numbers has authorities worried residents could be attacked — the three-tonne animals can be aggressive and kill more people per year in Africa than any other wildlife species.

Since Escobar’s death, the animals have thrived in the area’s large lakes and waterways, and grass pastures, and have brought a tourism boost.

However, the animals are having an impact on the native flora and fauna, with indications their presence is displacing some local species.

A new study by researchers at the University of California, San Diego, found the hippos were changing the quality of the water. The hippos feed at night then spend the day cooling off in the water where they defecate, changing the chemistry in the lakes.

Now a plan has been hatched to sterilise the animals. Ms Serna and a group from Cornare last year conducted in-the-wild surgical sterilisation of a female, the first in Colombia.

It’s a complex procedure that requires luring and trapping a hippo in a corral before using sedatives to put it to sleep. Just cutting through a hippo’s dense layers of skin, fat and muscle takes three hours.

The animal is then sterilised and stitched up and allowed to return to the wild while their recovery is monitored.

Later this year, Cornare will attempt multiple surgical sterilisations, as well as a chemical sterilisation technique that has been successful in pigs.

But they acknowledge that won’t be enough to contain a hippopotamus population that is estimated to quadruple over the next 10 years and could eventually reach into the thousands.
