Our Changing Planet BBC One, Sunday, 7pm

The launch of a definitive seven-year diary, documenting the fight to save our planet’s most threatened ecosystems. Six presenters meet the people fighting to restore the balance.

In the next seven years, the world’s population is set to increase by almost one billion. One million species could face extinction and rising seas will flood land where 147 million people currently live.

This series is the definitive diary of the planet’s threatened ecosystems.

Six presenters, passionate about the natural world, will visit six habitats and return over a period of seven years to chart pivotal changes in Earth’s history, documenting these stories, and meeting the scientists and local conservationists fighting to make a difference.

In the first year of this unprecedented documentary project, presenters Liz Bonnin, Chris Packham, Steve Backshall, Gordon Buchanan, Ade Adepitan and Ella Al-Shamahi will be in California, Iceland, the Maldives, Brazil, Kenya and Cambodia, exploring the ecological issues threatening the planet.

Experiencing the effect of urbanisation, desertification, the warming and acidification of our seas, melting glaciers, deforestation and economic development, each presenter will also discover stories of hope.

Can we turn the tide, halt the wildfires, save our coral reefs and prevent vast areas of the earth becoming too hot to inhabit? In this series our six eyewitness presenters will introduce us to the people who just may have the groundbreaking solutions that could restore Earth’s natural balance and save the wildlife under threat.
