The last episode in the series Frozen Planet looks at the man-made threat to the environment and examines how Earth's ice caps are changing and the likely consequences for the rest of the planet.

But US audiences will not be shown the final episode, where many fear a show that promotes the theory of global warming could upset viewers.

As Ben Stewart of Greenpeace said: "It's regrettable that millions of viewers in the US won't be getting the full story when they watch this mesmerising series."

Tell Discovery Channel that Americans should be shown the final episode of Frozen Planet and be allowed to come to their own conclusions.
