Blue Planet II To Highlight How We Are Choking The Oceans With Plastic

From the vast expanses of the seemingly endless open oceans to the microcosm of life found within a single rock pool, the latest offering from the BBC Natural History Unit has not disappointed. But as Blue Planet II draws to an end, it has a somber warning for humanity: we are smothering the oceans with plastic.

The final episode of the series will address the state of the oceans, and what humans have done to cause it. Often accused of skirting around the issue of how we are destroying the environment, the makers are dedicating a whole episode to how climate change, plastic, overfishing, and noise pollution are creating the greatest threat our oceans have seen in human history.

“For years we thought the oceans were so vast and the inhabitants so infinitely numerous that nothing we could do could have an effect upon them. But now we know that was wrong,” said David Attenborough. “It is now clear our actions are having a significant impact on the world’s oceans. [They] are under threat now as never before in human history. Many people believe the oceans have reached a crisis point.”

One particularly heartbreaking story involves the wandering albatrosses filmed for the Big Blue episode. Despite nesting on remote islands in the Antarctic Ocean, the scientists monitoring the birds on South Georgia's Bird Island have found that the chicks are still being killed due to plastic. The adults search thousands of miles of ocean seeking out enough squid and fish to feed their growing chicks, but often pick up plastic floating on the surface instead.

One researcher described finding that a chick died because a plastic toothpick had punctured its stomach. “It’s really sad because you get to know the birds and how long it takes the parents, away for 10 days at a time, to collect food for their chicks and what they bring back is plastic,” explained Dr Lucy Quinn.

“And what’s sad is that the plague of plastic is as far-reaching as these seemingly pristine environments.”
