People Fixing the World - Super seagrass

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.
