单集简介 ...

Seagrass meadows are one of the world’s most valuable underwater habitats. As well as providing food and shelter to thousands of species, seagrass is also known for its ability to store carbon and improve water quality, making it a powerful natural solution to tackle the impacts of climate change. But so much of the once thriving plant has disappeared from our planet. We visit North America’s eastern seaboard where scientists are looking at how a technique called ‘assisted gene flow’ is helping seagrass adapt and survive in warming waters. And we travel to a river estuary in northeast England to find out how local people are trying to regrow these lost meadows. People Fixing The World from the BBC is about brilliant solutions to the world's problems. We release a new edition every Tuesday. We'd love you to let us know what you think and to hear about your own solutions. You can contact us on WhatsApp by messaging +44 8000 321721 or email peoplefixingtheworld@bbc.co.uk. And please leave us a review on your chosen podcast provider.

  • Now let's jump into today's episode.

  • Beneath the ocean's surface lies one of the world's most valuable and most overlooked ecosystems,

  • a unique flowering plant that's disappearing at an alarming rate.

  • I mean when you look at them they just look so delicate and fragile and then you just leave them out here to the elements and obviously the tide washing them twice a day.

  • This is their home.

  • They're coming home.

  • I'm Mayra Anubi and today on People Fixing the World from the BBC World Service,
