Scientists, conservationists and other researchers are using audio soundscapes in innovative ways to record the natural world in rich detail and help develop strategies to preserve it. Gaia Vince visits the Dear Earth exhibition at London’s Southbank Centre where she interacts with the ‘Tell It To The Birds’ artwork by Jenny Kendler. This piece transforms spoken word into birdsong, which Jenny hopes will help raise awareness of threatened species. She is joined by Dr Patricia Brekke from the Zoological Society of London who reveals more about the threats faced by birds. We then visit the Knepp Estate to meet ecologist Penny Green, who reveals more about the value of audio for her work. Gaia then speaks to Dr Alice Eldridge, an acoustics expert from the University of Sussex, who has spearheaded the Wilding Radio project at the Knepp Estate in Sussex. She was curious to find out whether the sounds in the environment would change following the introduction of beavers to the estate. In collaboration with arts cooperative Soundcamp, she built high-quality, solar-powered equipment to continuously broadcast the soundscape from above and below the water.While we can record animals which we currently share the world with, what about those that have been lost forever? Cheryl Tipp, the British Library’s curator of wildlife and environmental sounds, looks after the library’s audio collection of more than 250,000 species and habitat recordings. She shares the heartbreaking tale of a now-extinct bird and explains why sound is such a valuable resource. Finally, Dr Tim Lamont, a marine biologist from Lancaster University, tells us why a degraded coral reef sounds different from a healthy one. He explains how broadcasting the sounds of a healthy reef can help attract more marine wildlife to an area.Presenter: Gaia Vince Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell Editor: Richard Collings

On Tuesday, the United Nations reported that the breach of the Nova Kakhovka dam on the Dnipro River in Ukraine will impact heavily on global food security, causing a rise in food prices and leaving many without access to clean drinking water. Nine days after the disaster Gaia looks to the future alongside Kira Rudyk, Ukrainian MP who is also leader of the opposition party Golos and Laura Wellesley, senior research fellow in the Environment and Society Programme at Chatham House.Earlier this week the three-year inquiry into COVID began, seeking ‘to examine the UK’s response to and impact of the COVID-19 pandemic and learn lessons for the future.’ Eyes are on the inquiry from many angles. Inside Science looks at what scientists hope to contribute and learn from it, with author and broadcaster Philip Ball.Also, a spike in North Atlantic sea temperatures has sparked concern among scientists. Richard Betts, head of climate impacts at the Met Office, talks through the factors that have coincided to form the anomaly.

For World Ocean Day, Gaia Vince finds out how the planet’s seas could help us to generate clean power, capture CO2 and feed the world. Gaia is joined in the studio by science journalist and marine biologist Olive Heffernan. She dives into the controversy regarding the potential of mining in deep oceans and discusses whether the seas could become the location for Industrial Revolution 2.0.We’re used to seeing seaweed wrapped around our sushi rolls but it’s so much more than that. As well as being a tasty addition to what we eat, seaweed plays a vital role in absorbing CO2. Gaia speaks to Vincent Doumeizel, a senior adviser on oceans to the UN Global Compact; he’s also the food programme director at the UK-based charity Lloyd’s Register Foundation. He’s confident that seaweed could enable us to sustainably feed a growing global population in the coming decades.Phytoplankton – microscopic species of algae that exist on the surface of the sea – also absorb huge amounts of carbon from the atmosphere. Sir David King, founder and chair of the Climate Crisis Advisory Group and former chief scientific adviser to the UK Government has the radical idea that artificial whale poo could boost phytoplankton growth, leading to an increase in fish stocks and, consequently, improved biodiversity in the oceans. He tells Gaia about his project and the potential it has for carbon capture.When we think of energy generation from the oceans, we tend to think of offshore technology such as wind turbines. But what about generating electricity using the water itself? Gaia speaks to Eco Wave Power’s Inna Braverman who reveals how her project harnesses the power of the waves by attaching to existing coastal structures such as piers and jetties, to provide a source of clean, renewable energy.
