Our time in Mexico comes to an end with the final episode of the expedition! We park our usual animal heavy chat to speak to Dr Kathy Slater (Mission Mexico: Welcome to the Jungle guest) about the communities who live around the biosphere and the threats it is under. Dare we say it - but we get serious for possibly the first time ever on the show! Firstly, we talk to Kathy about the honey production which many local communities are engaged in, and her work alongside local NGOs to help them move away from unsustainable agriculture practices. It's not just Kathy we speak to about the honey though - as we interview one of the local Mexican staff members Esteban about his own hives and what it's like producing honey...  alongside wildlife... ... in a drought.  The other big topic while we were on expedition was the "Tren Maya" train project that was being constructed. While we haven't mentioned this in the earlier episodes, this mammoth construction project was hard to avoid in Calakmul. Kathy helps explain a bit more about the train and offers some insight to the impact it could have to the region. Do read up on it - which has recently featured in the Natural History Museum Wildlife Photographer of the Year competition.  Finally, rest assured there's still some Jack and Roddy chat squeezed in - as we round up our success in seeing our Big 5, Jack gives his bird breakdown and we have the most grown up conversation we've ever recorded as we reflect on our time in the forest...   For more information on Operation Wallacea, check out www.opwall.com To support the show by leaving us a donation, please visit www.buymeacoffee.com/howmanygeese Follow our Instagram page for updates here www.instagram.com/howmanygeese
