Science: Kurt Vonnegut’s Ethical Vision, Tuna And Shark Extinction Risks

On this week’s show: How sci-fi writer Kurt Vonnegut foresaw many of today’s ethical dilemmas, and 70 years of tunas, billfishes, and sharks as sentinels of global ocean health

First up this week on the podcast, we revisit the works of science fiction author Kurt Vonneugt on what would have been his 100th birthday. News Intern Zack Savitsky and host Sarah Crespi discuss the work of ethicists, philosophers, and Vonnegut scholars on his influence on the ethics and practice of science. Researchers featured in this segment:

Peter-Paul Verbeek, a philosopher of science and technology at the University of Amsterdam and chair of the World Commission on the Ethics of Scientific Knowledge and Technology David Koepsell, a philosopher of science and technology at Texas A&M University, College Station Christina Jarvis, a Vonnegut scholar at the State University of New York, Fredonia, and author of the new book Lucky Mud & Other Foma: A Field Guide to Kurt Vonnegut’s Environmentalism and Planetary Citizenship Sheila Jasanoff, a science studies scholar at Harvard University

Next, producer Kevin McLean discusses the connection between fishing pressure and extinction risk for large predatory fish such as tunas and sharks. He’s joined by Maria José Juan Jordá, a postdoc at the Spanish Institute for Oceanography, to learn what a new continuous Red List Index using the past 70 years of fisheries data can tell us about the effectiveness and limits of fishing regulations. Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for custom publishing, interviews Joseph Hyser, assistant professor in the Department of Molecular Virology and Microbiology at Baylor College of Medicine about his use of wide-field fluorescence live cell microscopy to track intercellular calcium waves created following rotavirus infection.

Wildlife: The Black Rhino’s Comeback In Zimbabwe

In Zimbabwe, the mighty rhino is making a comeback. In southern Africa, the animal was poached to near extinction in recent decades. We visit a wildlife sanctuary, with an elite anti-poaching team, to see how the animal is being bought back from the brink.

It’s one of the most successful rhino conservation projects in Africa. In south-eastern Zimbabwe, a private wildlife sanctuary is working hard to bring endangered rhinos back from the brink. In decades past, the mighty Black Rhino was poached to near extinction in southern Africa. Its horn, almost worth its weight in gold, makes it a target for organised poaching gangs.

In 1998, the privately-funded Malilangwe Trust had a population of 28 white and 28 black rhinos, imported from South Africa. Today its rhino population numbers in the hundreds. Reporter Michael Davie, an Australian born in Zimbabwe, returns home to witness this extraordinary wildlife success story. He spends time with the sanctuary’s highly trained anti-poaching team, the Malilangwe Scouts, the tip of the spear against the ever present poaching threat.

“Individually you can’t win against poaching and we need every one of us to fight against poachers,” says Patrick, a Sergeant in the Scouts. “You have to be a team, a strong one.” Davie captures all the incredible action of the hectic “rhino ops” where specialists dart the animals from helicopters then move in on 4WDs as they dash across the park. Led by ecologist Sarah Clegg, the rhino ops team collect vital data on the herd.

“They’ve got this reputation of being bad-tempered and dangerous and they are, but I think it’s mostly that they’re just such emotional creatures,” says Sarah, who’s studied the animal for more than two decades. “They’re just insecure, you know? And so they need more love.” Malilangwe increased its rhino population to such an extent that last year, it relocated some of its Black Rhino herd to nearby Gonarezhou National Park — a former killing ground for rhinos.

“It’s what we all aim for in our careers as conservationists,” says Sarah. “It’s a wild park, so being able to put the rhino back into that park is like waking it up again.” This visually stunning story has a powerful message of hope. “Everyone needs to know the rhino is special,” says Patrick.

Wildlife: The Alpine Ibex – Return From Extinction

The ibex is the king of the Alps, famed for its curved horns and extreme climbing skills. But for centuries, these mountain goats were hunted by humans – to the very brink of extinction. A royal hunting reserve in Italy saved the Alpine ibex, but is climate change now threatening them all over again? We tell the story of their remarkable comeback and ask what the future might hold.

The Alpine ibex, also known as the steinbock, bouquetin, or simply ibex, is a species of wild goat that lives in the mountains of the European Alps. It is a sexually dimorphic species: males are larger and carry longer, curved horns than females. Its coat colour is typically brownish grey. 

Nature: Report Finds 30% Of Species Face Extinction

Nearly 30 percent of the 138,374 species assessed by the International Union for the Conservation of Nature (IUCN) for its survival watchlist are now at risk of vanishing in the wild forever, as the destructive impact of human activity on the natural world deepens.
