Seven Worlds, One Planet S01E02 - Asia

Asia is the largest and most extreme continent on our planet, stretching from the Arctic Circle in the north to the tropical forests on the equator. The animals here face the hottest deserts, tallest jungles and highest mountains found anywhere on Earth. But the continent has not always looked like this. These extreme worlds were created when India collided with the rest of Asia 30 million years ago, shaping the continent as we know it today. Animals here have adapted to the extreme environments in almost unbelievable ways.
