A documentary by Juliette Marquis

Ten years. Four continents.One radical idea.

Diving into the labyrinth of rhino horn trafficking, a filmmaker embarks on a decade-long journey to discover that tangled within the web of bureaucracy and ideology is a groundbreaking biotechnology with the potential to transform wildlife conservation.

i. The Film

What if you could biofabricate rhino horn in a lab?

For decades, we have tried to save species X or species Y of wildlife around the world. These species remind us that Mother Nature is all around us, despite our technological innovations. They are part of our connection to our very beginning. Saving them somehow connects us to the beginning of our own species. Despite all our efforts, and all the money poured into resolving this problem, we are still on the road to the extinction of many species. There are many reasons for this. One of them is wildlife poaching.

Horn Maker dives deep into the black market trade of arguably one of the most poached species on the planet: the rhinoceros. Its horn, unique amongst all wildlife, is priced more than gold or cocaine by weight. We meet the people along the chain of this trade: the poachers, the rangers, the carvers, the bureaucrats, and the conservationists who have dedicated their lives to saving wildlife.

Along the way, we come across an uncomfortable but innovative idea. What if all this effort could be flipped on its head by biotechnology? Biotech allows us to work with wildlife DNA without involving animals, but this innovation has never been applied to the black market of wildlife. Matthew Markus, a tech innovator, devises a plan and builds 3D-printing technology to create bio-identical rhino horns that sabotage, saturate, and collapse the illegal trade by exploiting its inherent greed from within.

The idea reverberates across the globe, with some calling him a genius and others calling for his arrest. Horn Maker follows Markus across Africa and Southeast Asia as he introduces his technology and the framework behind it to every player in the chain. Along the way, the film exposes striking contrasts in worldviews, from deeply rooted cultural traditions and trafficking networks to the cutting-edge realm of high-tech innovation. What results is the sheer witnessing of that effort. What it says about our culture. And a glimpse into reality as it is today, as opposed to the spin we have known up to now.

ii. Director's Note
Juliette Marquis on safari.

I have always felt bound to the natural world. In the mid-2010s, when the poaching of elephants and rhinos seemed at its worst, as they were being killed faster than they could be born, I resolved to understand who the people were and what methods were employed to make it better.

I traveled across Africa, sleeping in villages in huts beside the families of admitted poachers in Mozambique and Tanzania, and I sat with the top officials on three continents charged with stopping them. The more I saw and listened, the less certain I became. The hardest thing was to accept is that there is no villain to point to. The harm is in the shape of the system itself... in how we approach wildlife conservation. A single answer, applied everywhere, is doing some of the gravest damage to the ecosystems and the people it claims to protect. Every region carries its own history, its own needs, its own relationship to the land. Conservation has to meet them there.

THE PAPER TRAIL

A formal U.S. government memo from September 2020 suspended conservation grants after finding taxpayer funds had been linked to murder, rape, and torture of indigenous people. WWF, the sector's dominant player, received $333 million over 15 years and was repeatedly cited in the findings.
