Our Changing Planet
series, E1, S1
We begin the launch of the BBC's ambitious seven-year natural history project, in which six presenters visit six of the planet's most threatened ecosystems to meet the people fighting to restore the Earth's delicate balance. In this first episode, Steve Backshall, Chris Packham and Ella Al-Shamahi visit the Maldives, Iceland and Cambodia.
