Strap on your eco-friendly gear and prepare to be immersed in tales of transformation, recovery, and the relentless pursuit of a better world. Join adventurer Phoebe Smith in Egypt's Red Sea (literally) where she meets the resort cleaning up its act - and the ocean. Red Sea Safaris in Marsa Alam (one of the first PADI eco-dive centres in the world) firmly pushes back against the mass tourism model, and empowers divers to be part of the solution by offering the Dive Against Debris course free of charge, alongside other conservation first initiatives, and in doing so improves both the land and underwater world for everyone.  Also coming up: How to travel sustainably on a budget; Discover the top 10 places to try diving; I meet ultrarunner and co-founder of Black Trail Runners Sabrina Pace-Humphreys to discuss why Lanzarote is just like running in the Sahara desert and why she never travels without her running shoes. In our regular gear chat we consider the most eco-friendly snorkelling kit;  be awed and humbled by child solider turned artist Peter Oloya, who is using his talent to empower other survivors in Uganda; and in our Wander Woman of the Month - learn about the woman who made waves becoming the first scuba instructor in the USA - Dottie Frazier. www.Phoebe-Smith.com; @PhoebeRSmith
