In the concluding installment of our two-part season finale of Naked Oceans, we get a bit thoughtful and contemplate what might lie in store for the future of the oceans. Helen catches up with some of the marine experts we've heard from throughout the last two series and asks them about what they think the future might hold. Are they ocean optimists or pessimists? What solutions will be needed to protect the oceans of the future? And on a more positive note, we ponder what great ocean discoveries might lie ahead.
