An episode of the BBC’s Frozen Planet documentary series that looks at climate change has been scrapped in the U.S., where many are hostile to the idea of global warming.

British viewers will see all seven episodes of the multi-million-pound nature series throughout the Autumn.

But U.S. audiences will not be shown the last episode, which looks at the threat posed by man to the natural world.

It is feared a show that preaches global warming could upset viewers in the U.S., where around half of people do not believe in climate change.
