It wasn't my usual holiday experience: standing on the I beach, getting ready to release a baby sea turtle no bigger than my hand. But that was how I spent my final night in Puerto Vallarta, Mexico. During my week there, I 5 had seen other tourists releasing the turtles in the early evening, and as my stay came to an end, I decided to join in. I asked the hotel receptionist who the organiser was and she told me that his name was Oscar Aranda. Oscar runs Sociedad Ecológica de Occidente conservation project that brings residents together to pune tourists save the sea turtles of Puerta Vallarta. These turtles are under threat from poachers who want their meat and eggs. But Oscar and his volunteers collect the eggs and take them to protected areas where they are allowed to hatch in safety. Then, within 24 hours, they are taken back to the beach where tourists like me join in the conservation effort. We listened to Oscar's instructions. He told us that the turtles were released as the sun goes down so the bright lights of the hotels and nightclubs don't stop them finding their way back to the sea. We stood a few metres from the sea's edge holding our one-day-old turtles carefully in both hands. At a signal from Oscar, we gently placed them on the sand, stepped back and watched as they crawled slowly into the sea. I watched until my baby turtle vanished beneath the waves. Back home, I still think of the tiny baby turtle and wonder where it is now. Did it make it to the open sea? Is it safe? Oscar Aranda has dedicated his life to saving the sea turtles; I only gave a few minutes of my time, but those 35 minutes will stay with me for a lifetime.
