When Pablo Escobar smuggled four hippos into Colombia in the 1980s to stock his private zoo, no one imagined the animals would outlast his drug empire by decades. Now numbering at least 169 according to a Colombian government estimate published in 2024, the hippos roaming the Magdalena River basin have become the largest invasive population of the species outside Africa. And their fate has drawn an unlikely suitor: Anant Ambani, the 29-year-old son of Mukesh Ambani, chairman of Reliance Industries and one of the wealthiest people on the planet.
Through his Vantara wildlife facility in Jamnagar, India, the younger Ambani has proposed relocating 80 of the hippos rather than allowing Colombian authorities to euthanize them. The offer landed just as Bogota formalized a management plan that includes lethal measures as a last resort, setting up a collision between international animal welfare ambitions and the ecological emergency unfolding along Colombian waterways.
How Colombia reached this point
Colombia’s hippo crisis did not arrive overnight. After Escobar was killed in 1993, his Hacienda Napoles estate fell into disrepair. Most of his exotic animals were relocated, but the hippos proved too large and dangerous to move easily. Left largely unchecked, they bred prolifically in the warm, water-rich lowlands of the Magdalena Medio region.
For years, the government’s response was piecemeal. Veterinary teams carried out rounds of surgical sterilization, backed by the Instituto Humboldt and the Universidad Nacional’s Instituto de Ciencias Naturales, but the procedures were expensive, risky, and too slow to keep pace with the animals’ reproduction rate. A handful of hippos were relocated to facilities abroad, including transfers to sanctuaries in India and Mexico in 2024, but those efforts barely dented the population.
The legal turning point came when the Administrative Tribunal of Cundinamarca ruled, through a popular action lawsuit, that the hippo overpopulation violated Colombians’ collective right to a healthy environment and ecological balance. The court ordered the Ministry of Environment to move beyond ad hoc responses and issue binding, long-term regulations.
The result was Resolution 0774 of 2024, which established a formal Plan de Manejo y Control built on four pillars: translocation, sterilization, confinement, and, as a last resort, euthanasia. The ministry stressed that lethal control would be considered only when other tools could not adequately protect ecosystems or public safety.
What Ambani is proposing
In a formal statement from Vantara, signed by CEO Vivaan Karani on Ambani’s behalf, the facility offered to take in 80 hippos, the same number that had become associated in public debate with a potential cull. According to Indian Express reporting, Ambani sent a letter directly to Colombia’s environment minister describing what the outlet characterized as a “fully resourced relocation program” to be carried out under the direction and approval of Colombian authorities.
The same Indian Express report stated that Vantara pledged to cover the costs of capture, quarantine, international transport, and long-term care. No dollar figure was included in the reporting, and no independent verification of the pledge’s financial scope has been published. The facility was described as featuring large enclosures designed to resemble the hippos’ ancestral African riverine habitats. CBS News reported that Ambani framed the initiative as a humane alternative that would spare a substantial portion of the herd from being killed.
For context, the 2024 transfer of just a small number of hippos to international sanctuaries required specialized crates, heavy sedation protocols, and weeks of veterinary preparation. Scaling that operation to 80 animals, each weighing up to two tons, would demand heavy-lift aircraft or ships, extensive quarantine arrangements, and coordinated export and import permits from both Colombian and Indian regulators. The absence of a public cost estimate makes it difficult to gauge whether the pledge matches the logistical reality.
Why Colombia has not said yes
As of May 2026, there is no formal confirmation from the Colombian Ministry of Environment that it has evaluated or accepted Ambani’s proposal. The ministry has opened an institutional email channel to receive offers related to hippo management but has not singled out the Vantara initiative for public comment.
Part of the hesitation is practical. Transporting 80 semi-wild hippos across continents raises serious biosecurity questions. Both governments would need to approve disease monitoring plans and ensure the animals do not introduce pathogens or ecological disruptions to their new environment. India’s climate and regulatory landscape differ sharply from Colombia’s, and the hippos’ status as an invasive species complicates the legal picture on both ends.
There are also questions about Vantara itself. While the facility has been promoted as a large-scale animal rescue and rehabilitation project, no independent assessment of its capacity to house 80 adult hippos has been published by Colombian authorities or international wildlife bodies. Some past reporting has raised questions about transparency and operational standards at Vantara, though those concerns have not been formally examined in the context of this specific proposal.
Coverage by the Associated Press emphasized that Colombia had approved a plan to kill up to 80 hippos, citing the environment minister’s concerns about cost and the limits of sterilization. But the ministry’s own resolution frames euthanasia as one tool among four, not a standalone target. Whether the figure of 80 represents a firm number, a ceiling, or a preliminary estimate has not been clarified in official documents.
The view from the Magdalena River
For communities along the Magdalena basin, the debate over Ambani’s offer can feel distant from daily reality. Hippos have been reported wandering near farms, crossing roads, and entering fishing areas. Authorities have documented incidents of aggression and close calls with residents and livestock. As the population grows, so does the likelihood of serious human-wildlife conflict.
Many local stakeholders want the risks reduced quickly, even if that means accepting lethal control for some animals. International campaigns focused on saving the most visible hippos can appear disconnected from the experience of living alongside a herd that is expanding faster than any intervention has managed to contain.
Colombian scientists involved in drafting the management plan have repeatedly emphasized that the hippos are not simply charismatic megafauna. They are powerful ecosystem engineers whose grazing, dung output, and movement through waterways reshape river chemistry, displace native species, and alter habitats in ways that ripple through the food chain.
Conservation scientists remain divided
The proposal has split the conservation community. Some international organizations have applauded Ambani’s offer as a rare case of private funding stepping in to save individual animals that would otherwise be culled. Others warn that large-scale relocation could set a problematic precedent, encouraging the idea that invasive populations can always be shipped elsewhere rather than managed in place.
Colombia’s government has tried to position its plan as both scientifically grounded and open to collaboration. Officials have said translocation and sterilization remain central pillars of the strategy and that euthanasia will be applied only when other measures cannot feasibly address specific groups of animals. In principle, a carefully vetted relocation to a high-welfare facility could fit within that framework. But until Vantara’s proposal undergoes a formal evaluation covering veterinary, ecological, legal, and financial dimensions, it is impossible to say whether the Indian option will be folded into the official plan or remain an unimplemented idea on the sidelines.
A decision shaped by history and urgency
The standoff over the Escobar hippos reflects one of conservation’s hardest tensions: how to balance concern for individual animals against the need to protect entire ecosystems. These hippos are at once victims of a criminal past, symbols of a notorious drug lord’s excess, and active agents of environmental change in a river system that was never meant to support them.
Until Colombian authorities issue a clear response to Ambani’s relocation offer and specify how it would interact with their existing tools of sterilization, confinement, and euthanasia, the fate of the 80 hippos at the center of this controversy will remain unresolved. What is certain is that the clock is biological: every breeding season that passes without decisive action adds more animals to a population that has already outpaced every effort to control it.
