Asia, S1 E2, Above the Clouds

Asia is the most mountainous continent on earth. From the forested peaks of the tropics to the hostile heights of the Himalayas, Asia's mountains are home to an astonishing abundance of specialised plants and wildlife. In India, elephants live in high-altitude tea plantations, and in Thailand, mountainous caves hide the planet's greatest gathering of swifts. In Pakistan, markhor live life truly on the edge, fighting for mates atop towering cliffs, and in Nepal, the forested foothills of the Himalayas provide hiding places for one of Asia's shyest mammals, the red panda.
