National Geographic photographers Beverly and Dereck Joubert gave a TED talk last month in which they discussed their documentary, The Last Lions. In case you missed it, or if you’re not in LA, New York or Washington DC where the film is screening, now you’ve got another chance to see these amazing and unsettling images. There’s a book to accompany the project, which tells the story of a family of lions in Botswana’s Okavango Delta. I’m a big fan of TED talks, a sucker for gorgeous wildlife photography, and I will forever be in awe of the lengths to which National Geographic photographers will go to tell us these important stories of conservation. Read all about and watch the TED talk at the Brain Pickings blog, and follow that with a visit to the official Last Lions film site. There you’ll find photo galleries and information about the filmmakers and the Big Cats Initiative to help preserve these animals and their habitats.
