Welcome home. A place 200 million years in the making. Long ago, our planet had only one gigantic land mass. Then something momumental happened. That supercontinent ruptured and seven different worlds were born. Each of these worlds - or continents - evolved, and continues to evolve, its own way of life. From the jungle of the Congo or the majestic Himalayas to the densely populated wilds of Europe or the comparatively isolated Australasia, 'Seven Worlds' explores the natural wonders tha give each of our continents its distinct character.
