Around the globe, unique and fascinating species face extinction from hunting and habitat destruction, which affects vulnerable animals in every kind of environment. Biologists, conservationists, wildlife preservation centers and zoological parks work to breed and shelter rare and critically endangered animals when and where they can, but many species are down to the last few individuals and face an increasingly uncertain future. For some, however, the future is all too clear. Lonesome George, a Pinta Island tortoise from the Galapagos Islands, is the very last of his kind.

In the animal kingdom, there's no shortage of bizarre behaviour. This episode burrows high and low ground to unearth some of the creepiest creatures who crawl on this planet!

And that's just a sampling of over 20 species whose antics you can hardly believe...or turn away from. (www.youtube.com)

Broadcast 2012. In this episode, Chris travels to North America to witness the annual miracle of the temperate forest: the destruction of its ecosystem in winter, followed by it rebuilding itself in spring. Chris Marvels at the exquisite timing that is necessary in two particularly wonderful stories - the story of how the Canada lynx depends for its prey on a caterpillar high up in the canopy, and the story of why the giant trees of the north-west are dependent on bears and salmon.
