Whilst in Costa Rica we accompanied the marine biologists on several excursions. Often it felt like we were hindering their scientific process rather than helping as although we had bucket loads of enthusiasm we had little training in any specific conservation technique. However, sometimes we seemed useful and this film portrays one such occasion, when we dove in murky, turbulent waters to retrieve a receiver that had been collecting data for the past 3 months. It was truly fulfilling, a real adventure, all activism has a feel good factor attached to it somewhere but this day will stand out in my memory as an example of what satisfies me the most; doing positive work in slightly dangerous, physically and mentally testing conditions and coming out of it with a successful result. Good times indeed.

The plan is to use the data to determine what areas of the ocean sharks and turtles inhabit most and for what reasons, and then to put forward a case for a new marine conservation area based on these findings. If the animals can be left alone long enough for them to repopulate their species – at the moment so many fish and turtles are being caught before they’ve even had time to reproduce so extinction is close on the horizon for species such as shark, turtle and tuna – they may still have a chance of survival, as will our oceans and therefore us. In case you didn’t know, the oceans produce 50% of the oxygen that we breathe so if we allow them to fall into bad health, we are all likely to suffer. If you enjoy my films and think they are important, please share around, thanks.
