Overfishing, oil drilling, pollution and climate change are imperilling the ecosystem. But ocean sanctuaries could help protect what belongs to us all, says Greenpeace director John Sauven
The awful news that all but two penguin chicks have starved to death out of a colony of almost 40,000 birds is a grim illustration of the enormous pressure Antarctic wildlife is under. The causes of this devastating event are complex, from a changing climate to local sea-ice factors, but one thing penguins, whales and other marine life dont need is additional strain on food supplies.
Over the next year we have the opportunity to create an Antarctic Ocean Sanctuary the largest protected area on Earth which would put the waters off-limits to the industrial fishing vessels currently sucking up the tiny shrimp-like krill, on which all Antarctic life relies.
In 1990, the Voyager 1 space probe looked back at Earth from six billion kilometres away and took a historic selfie of our solar system. What it saw, according to renowned astrophysicist Carl Sagan, was a pale blue dot.
Our planet is a blue planet, echoed David Attenborough, in his opening words to the BBCs landmark Blue Planet series. With over 70% of our world covered by water, this is no exaggeration. Our oceans can be seen from across the solar system.
The majority of this water falls outside of national borders. In fact, almost half of our planet is a marine natural wonder outside the boundaries of flags, languages and national divisions. These vast areas cover 230 million square kilometres, and they belong to us all. To give a sense of scale, thats the size of every single continent combined, with another Asia, Europe and Africa thrown in for good measure. The size of our oceans may seem overwhelming. Our collective responsibility to protect them, however, should not.
It wasnt long ago that the oceans were thought to be too vast to be irrevocably impacted by human actions, but the effects of overfishing, oil drilling, deep sea mining, pollution and climate change have shown that humans are more than up to the task of imperilling the sea and the animals that live there.
