Wildlife crossings are having a moment
Mongabay Newscast
Nearly three years ago, Newscast guest, author and journalist Ben Goldfarb his book Crossings, which is about wildlife crossings and road ecology. Wildlife crossings help reconnect habitats fragmented by road networks, reducing collisions, helping protect threatened wildlife, and improving genetic diversity. Since that conversation, Goldfarb has the growing popularity of wildlife crossings worldwide. He returns to the Newscast to detail how, where, and why wildlife crossings are becoming increasingly funded and built. “Probably the biggest factor is that at this point, the evidence that...

The radical plan to rethink work, wealth and planetary well-being
Mongabay Newscast
A group of more than 40 researchers spent 20 months devising a plan for the world to achieve ecological sustainability within , all while seeing incomes rise for 98% of the global population and reducing working hours for everybody by half to two and a half days a week. The plan to achieve this by 2100 is laid out in the recent “.” If it sounds utopian, Lucas Chancel, the co-director of the and editor of the report, is the first person to acknowledge this, but explains why it’s not only possible — there’s even historical precedent for many of the measures the report outlines....

Mongabay Newscast
Theonila Roka Matbob grew up next to what was — at the time — the world’s largest open-pit mine in Bougainville, an autonomous island in Papua New Guinea, operated by a subsidiary of Rio Tinto. This mine wrought environmental and social devastation on the community of Panguna for decades. And many of these impacts carry on today, says Roka Matbob, who is an Indigenous Nasioi woman and politician. With the help of Jubilee Australia and the Human Rights Law Centre, Roka Matbob was able to file a legal complaint with Australia’s National Contact Point for Responsible Business Conduct. As...

She wrote it for readers and listeners like you. “I think we're all in our own ways grappling...

Australia claims it’s ‘on track’ to meet its environment targets. Scientists disagree
Mongabay Newscast
Australia is one of 17 “megadiverse” countries that account for 70% of Earth’s biodiversity. However, Australia is unique in having the highest mammalian extinction rate in the . That makes conservation on the island continent, where most of the wildlife is found nowhere else on Earth, all the more urgent. Conservation and environmental scientists have come out the Australian federal government’s claim that it’s “on track” to meet most of its targets under the agreed upon at the U.N. biodiversity summit in 2022. This week on the Mongabay Newscast, , a professor of wildlife...

The world must address pandemic threats urgently, says former CDC officer
Mongabay Newscast
“[The]cruel irony here [is] that the world cannot get its act together to address these threats … people are dying, animals are suffering, we're losing rainforest … these are all interconnected threats,” Neil Vora tells me on this week’s episode of the Mongabay Newscast, just a day after the World Health Organization (WHO) reported more than 80 deaths in the Democratic Republic of Congo from an outbreak of the Ebola virus.

A new Netflix documentary captures rare mountain gorilla behavior
Mongabay Newscast
“That might be something that you see in a decade, not in two years of filming,” Tara Stoinksi, CEO of the Dian Fossey Gorilla Fund, tells me. The behavior she’s referring to occurs in mountain gorilla groups, such as a “dominance transfer,” where a younger male silverback takes over leadership from an older male, and infanticide, where an outsider or ostracized gorilla kills the offspring of a new mother within the group. The former of these was captured on camera within days of filming for the new Netflix documentary A Gorilla Story: Told by David Attenborough. Stoinski joins the...

Centering an Indigenous approach to forestry through reciprocity, not extraction
Mongabay Newscast
Forester and scientist Suzanne Simard is well known for her landmark 1997 , which demonstrated that two distinct species of trees could share resources. At the time, it turned traditional Western forestry thinking on its head. Instead of the Darwinian view of trees as being in competition with each other, it introduced the idea that these trees may actually help each other, and that industrial logging practices may be missing the forest for the trees. In recent years, Simard has been advocating for Indigenous knowledge as the only way to save the Earth and its forests. Environmental reporter...
info_outlineNearly three years ago, Newscast guest, author and journalist Ben Goldfarb discussed his book Crossings, which is about wildlife crossings and road ecology. Wildlife crossings help reconnect habitats fragmented by road networks, reducing collisions, helping protect threatened wildlife, and improving genetic diversity.
Since that conversation, Goldfarb has documented the growing popularity of wildlife crossings worldwide. He returns to the Newscast to detail how, where, and why wildlife crossings are becoming increasingly funded and built.
“Probably the biggest factor is that at this point, the evidence that wildlife crossing structures are effective is just overwhelming. Maybe 20 years ago, you could've theoretically said, ‘Well … we don't necessarily know that …’ but here in 2026, we just have a lot of scientific research basically showing that animals of all shapes and sizes use wildlife crossings,” Goldfarb says.
He takes us to locations in South America, North America and Europe, where this particular type of infrastructure has rare nonpartisan political support. A bill is currently before the U.S. Congress to make the Wildlife Crossings Pilot Program permanent. Public surveys show overwhelming support for wildlife crossings in the United States. Goldfarb explains that the positive reception may also be due to the visual nature of one iteration of crossings, the highway overpass, which a source of his long ago described as “billboards for connectivity.”
“I love wildlife crossings for … their ability to … just remind us that we're sort of global citizens of a planet that we share with wildlife.”
