David Attenborough Observes A Natural World In Crisis If you were to make a list of celebrities of the natural world, Sir David Attenborough would most likely make the cut. You probably know him from television series such as Life on Earth, The Secret Life of Plants, Living Planet, and so many more. Now, at age 94, he’s written a new book, A Life on Our Planet: My Witness Statement and Vision for the Future, and filmed an accompanying Netflix documentary. The book and film talk about the changes to the natural world in the time he’s been alive—from overfishing, to deforestation, to climate change—and urge us to adopt a more sustainable future. David Attenborough and BBC producer and science writer Jonnie Hughes join Ira to talk about the challenges the world is facing today, and steps we can take toward sustainability. Read an excerpt of Attenborough’s new book. China’s Chang’e-5 Lander Touches Down On The Moon It was an historic week for space news. On Tuesday, China’s Chang’e-5 lander touched down on the moon’s near-side, near Mons Rumker, a mountain in the “Ocean of Storms” region. Over the course of two days, the lander collected several kilograms of lunar soil—the first samples collected in over 40 years. If all goes well, the Chang’e-5 ascension module and its cargo will reunite with the orbiter on December 6th. Also this week, a video from the control tower of the Arecibo Observatory in Puerto Rico captured the moment its final cable snapped. The platform came crashing down on the dish, effectively ending the future—but not the legacy—of this iconic observatory. Ira and Loren Grush, senior science reporter for The Verge, pay tribute, and discuss the historic space news of the week. This Wednesday, the United Kingdom announced approval for a COVID-19 vaccine through an emergency authorization, beating out the U.S. and most other countries. The vaccine is being produced by the U.S. pharma company Pfizer and German partner BioNTech. And the first U.K. vaccinations may start as early as next week. Nsikan Akpan of National Geographic talks about how this vaccine works and what it means for the vaccination schedule for the rest of the world. Subscribe to this podcast.
