As the planet continues to sprint toward an inferno-like, unlivable state, David Attenborough is returning to the BBC with a new nature documentary that promises to be both depressing and necessary: Extinction: The Facts.

Per the BBC, the one-hour documentary will focus on the precariousness of the natural world, and will go “beyond our emotions to investigate what the extinction crisis means, not just for the planet but for every one of us. World-leading scientists will explore why species are disappearing at such an alarming rate and will ask what that means for humanity.” Still, it seems safe to bet this one will be a downer.

The series follows a bombshell 2018 report from the World Wildlife Fund that found the Earth’s animal, bird, and fish populations have shrunken by 60% since 1970, with human activity predominantly to blame. A recent United Nations report also found that 1 million plant and animal species currently face extinction.

According to Deadline, Extinction: The Facts will examine species such as the blue whale, which relies on krill populations to survive. In a statement, BBC Controller, Factual Commissioning told Deadline, “Even today a record number of wildfires are burning in the Amazon and around a million species of plants and animals face extinction.... We know our audience has a hunger to understand how these urgent environmental issues affect them, but more than that, what they themselves can do in their homes. We’ve proven with Big Blue Live, Climate Change the Facts, Drowning in Plastic that we can bring big broad audiences to complicated environmental subjects. This is television that matters. And I’m thrilled Sir David Attenborough continues to work with us to make it.”

As climate change continues to ravage the planet, programming like this will likely become both more common and more vital than ever. Attenborough also recently narrated Netflix’s Our Planet, which debuted this spring and included a heartbreaking look at walrus attempting to climb a steep cliff and falling to their deaths. “There’s probably [200] or 300 hundred dead walrus on about a half-mile stretch of beach here,” one documentarian said while watching the scene. “They’re exhausted because they have to swim a hundred miles now to get to food, and then coming back here because it’s the only place to sleep. They used to sleep on the ice, dive down, eat food, sleep on the ice—easy.”

“This is the sad reality of climate change,” added another documentarian. “They’d be on the ice right now if they could be. There’s no option but to come to land. They’re just a danger to themselves.”
