Dr. M. Sanjayan explores seven of Earth's bellwether biomes.

Steve Backshall visits the Maldives, a country facing significant climate challenges. He finds these challenges are galvanizing the science community. Liz Bonnin returns to California to investigate some surprising solutions for the onslaught of wildfires. Chris Packham is in Greenland to learn more about the effects of global warming and the rate at which snow and ice are melting in the Arctic.

It’s year two of BBC’s ambitious, seven year project charting the fortunes of six of Earth’s most threatened ecosystems, and in the second episode we join three presenters as they celebrate the experts and communities fighting to rebalance another trio of vulnerable habitats.

Our coral reefs are at a tipping point. Consecutive bleaching, caused by climate change, are leaving them with challengingly short periods of time to restore themselves. The science community is experimenting with innovative techniques that just may hold the key to saving the coral. Steve Backshall catches up with the scientists who are making groundbreaking discoveries to save the reefs.

A look at two world-leading projects designed to tackle the crises facing Earth's rivers.
