BBC - Our Changing Planet Series 1 (2022)

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.

Chapter 1:
Steve Backshall travels to the Maldives, an area facing significant challenges because of climate change. Warming seas and the acidification of the oceans have led to coral bleaching on a massive scale, destroying the surrounding ecosystem. The biodiversity of the reefs provides food security, income and other benefits to the people of the Maldives, and Steve finds that they are working hard to try to stem the tide of destruction. He also goes diving off the reefs to check on a group of manta rays, whose presence offers a clear indication of the health of the reef.

Chapter 2:
Liz Bonnin travels to California to learn about the increasingly invasive wildfires hitting the headlines. Scientists can see clear links between the fires, climate change, raised temperatures and an extended drought season. There is one crucial element that is key to a sustainable future in California: biodiversity. Loss of keystone species and large carnivores is a threat to the state's ecosystems, and conservationists and scientists are mobilising to save wildlife from wildfires and to treat their burns.
