Not to worry you or anything, but,
O'Shea has found plastic in the stomachs of giant squid. "The oceans are very sick," he says. "The predictions that I have, in terms of published reviews, maintain that we will see the collapse of all commercial fisheries by 2025. Any fish that you're getting on your plate when you go down to the supermarket will be gone by 2025," commercially extinct though not absolutely extinct. "It's going to be another 25, 30 years after 2025 before levels might have climbed up again to justify some sort of commercial fisheries. But during the intervening years, we'll have had to go for an alternative food source and I don't think that people are going to be so interested in completely annihilating the oceans all over again."
