We live in a world that gets smaller every day. The media, intercontinental transport and the exporting and mixing of cultures make borders seem increasingly closer and more diffuse. As a consequence, there is a tendency to think that there are hardly any areas left on the planet untouched by the influence of civilised man, places that still follow the millenary guidelines of their own history. But nothing could be further from the truth. Lost Worlds will introduce us to such places where times seems to have stood still, immune to the aggressive cultural tendencies and techniques of the western world. They are places that follow their own course, their own evolutionary and cultural paths where species, including man, have found adaptive solutions different than ours. Nature in its wildest state, the rarest species on earth, the most isolated indigenous races, the ruins of ancient lost empires, history and legend: these are the pillars of a new documentary series which will show the permanence of diversity and the mystery of a planet which still harbours fascinating Lost Worlds within.
