Inside Nature's Giants (PBS, 1-pm) - Australia may not come to mind as home to camels, yet in the middle of this vast continent there are more than one million feral dromedaries roaming around.
European settlers introduced them more than a century ago to help build Australia’s railways and explore the Outback. But with the advent of roads, cars and trucks, camels were no longer needed, so their owners released them into the desert. Camels have adapted so successfully that they're playing havoc with the environment, so the government has introduced a program to limit their numbers.
