As the human population increases so too does our demand for food, but in the face of the climate crisis scientists are seeking alternative and sustainable solutions to traditional agricultural practices. In this episode of IFLScience, The Big Questions, we teamed up with BBC Earth to speak with Luca Gamberini of Nemo’s Garden to ask: Is the future of farming underwater? Nemo’s Garden is working to create an alternative system of agriculture that uses the oceans and other bodies of water to establish a more sustainable way of farming. In this episode, host Rachael Funnell speaks to Gamberini about the complexities of farming underwater and how their innovative agricultural practices could help to protect and conserve the planet. This episode is presented in partnership with BBC Earth as part of #OurGreenPlanet – an impact initiative that aims to protect our green spaces by sharing the extraordinary stories of people around the globe dedicating their lives to positive change.
