Bear Grylls' latest show, NBC's Running Wild With Bear Grylls, involves the survival expert taking celebrities on wilderness adventures—and he's lined up quite the celebrity for the show's second season. President Obama will go on an Alaskan trek with Grylls, former host of Discovery's Man vs. Wild, for a special episode of the show airing later this year, NBC announced today. Why? The episode "will highlight the effects of climate change in that area," USA Today explains. (It's not Obama's first foray into nontraditional media.)
