Bear Grylls dropped by Discovery Channel Other episodes saw Grylls dropped by parachute into jungles and deserts, survive for days by eating snakes, sleep in snow holes and wrap a urine-soaked T-shirt around his head to ward off dehydration. Heather Krug, a spokesman for the adventurer, added: "Bear's goal has always been to make life-empowering shows for his many fans around the globe, and he has taken great risks to bring Discovery such award winning programming over seven seasons. Unfortunately, Bear and Discovery have not been able to come to mutual agreement on new programming, and he disagrees with Discovery's decision to terminate current productions. Bear has loved the 'Man vs Wild' journey and looks forward to producing further cutting edge content again soon for his loyal audience. Grylls learnt parachuting, jungle warfare and combat survival during three years in the elite SAS. He climbed Mount Everest at the age of 23. As well as his television work, Grylls is a sought after motivational speaker and the author of a number of books, including fiction for teenagers and a bestselling autobiography. He lives on a converted barge on the River Thames in London with his wife Shara and their sons Jesse, Marmaduke and Huckleberry.
