Asked what worried him the most about the crew’s findings, the 91-year old said: ‘Two things. One of course is the rising temperature, and particularly in the last programme it is illustrated what happens if the temperature goes up by 1.5 degrees.
‘The second thing is plastic. Plastic in the ocean. Now what we’re going to do about 1.5 degrees rise in the temperature of the ocean over the next 10 years, I don’t know, but we could actually do something about plastic right now. And I just wish we would.
‘There are so many sequences that every single one of us have been involved in, even in the most peripheral way, where we have seen tragedies happen because of the plastic in the ocean.
‘We’ve seen albatross come back with their belly full of food for their young and nothing in it.
‘The albatross parent has been away for three weeks gathering stuff for her young and what comes out? What does she give her chick?
‘You think it’s going to be squid, but it’s plastic. And the chick is going to starve and die.
‘There are more examples of that. But we could do things about plastic internationally tomorrow.’
Enlightening how he hoped the series would encourage viewers to think about our influence on the environment, he continued: ‘We have a responsibility. Every one of us. We may think we live a long way from the oceans but we don’t.
‘What we actually do here, and in the middle of Asia and wherever has a direct effect on the oceans and what the oceans do, then reflects back on us.
