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. Did you know the Northernmost Asia has temperatures that can drop below minus sixty degrees celcius?

This week, Martin Bester looks forward to the second episode of BBC Earth’s “Seven Worlds One Planet,” focused on Asia. The biggest continent on Earth, Martin looks into highlights including Walruses, Polar Bears, monkeys and a snake!

The Polar bear fur is translucent, and only appears white because it reflects visible light. Beneath all that thick fur, their skin is jet black? How incredible!
