About Our Film
This sweeping cinematic short film showcases the untold story of the porcine zona pellucida (PZP) contraceptive vaccine. PZP is transforming conflict between humans and wildlife into peaceful coexistence from Africa’s vast savannas, through New York State’s suburban neighborhoods, to the American West’s rugged mesas.
About Our Film
A FILM ABOUT PZP
Humane Wildlife Fertility Control
Project Coexistence journeys across continents as scientists Dr. Audrey Delsink in South Africa and Dr. Karen Herman in New Mexico prove that a humane way of coexisting with animals has arrived: PZP.
Our film chronicles how South African researchers proved the critics wrong about the porcine zona pellucida contraceptive vaccine (PZP) and how their vision changed the law.
Our film reveals how researchers took PZP out of the laboratory and brought it into the field, blazing the trail for what’s happening now in South Africa and the American West.
Our film recalls how PZP changed Dr. Allen Rutberg’s career when he partnered with Drs. Jay Kirkpatrick and John Turner to develop humane animal contraception.
ABOUT ANIMAL CONTRACEPTION
A STORY OF INNOVATION: WILD BIRTH CONTROL
Dr. Allen Rutberg recalls the moment PZP changed the trajectory of his career. He was in the middle of a field study at Assateague Island National Seashore in the 1980s when the Park Service decided its wild horse population was too dense, “… and these two cowboys came riding into Assateague and that was the end of my study.” But it marked the beginning of a decades-long partnership with Dr. Jay Kirkpatrick and Dr. John Turner—the researchers who took PZP out of the laboratory and breathed life into it in the field.
ABOUT PZP (PORCINE ZONA PELLUCIDA)
PZP MYTH-BUSTING: ENVIRONMENTAL ANIMAL CONTRACEPTION
No place on this planet is spared from the impact of humans. Though Africa is vast, fences divide historic ranges of elephants that are vital to a healthy ecosystem. But fenced-in, populations can quickly grow too large for the area. Conflicts with humans can erupt. Ecosystems decline. Enter: PZP.
ABOUT SAVING WILD LIVES
A STORY OF IMPACT: HUMANE PZP VACCINE
Historically, humans have attempted to manage animals such as wild horses, deer, and elephants through relocation, fear tactics, or culling— techniques that can backfire and, in fact, spur population growth.
