It's only a couple of days since the Esperanza set out on the Defending Our Pacific Tour, but already the crew are deeply engaged in the fight to save Pacific tuna from decimation.
Tuna are the main target of industrial fishing fleets from Asia, USA and the EU. Between them they took over 2.5 million tonnes last year alone - a totally unsustainable amount. And the indiscriminate nature of their fishing methods means that thousands of sharks and turtles also die needlessly in their nets.
