Antarctic sanctuary: The Weddell Sea quest | earthrise

Environmental correspondent Nick Clark follows a Greenpeace campaign to create the world’s largest sanctuary in the remote Weddell Sea in Antarctica. The continent’s spectacular wildlife is under threat from climate change and human activity such as fishing and deep-sea mining.
The campaign is yet to succeed. And yet, it is critical it does. Conservation groups and the UN are calling for governments to protect 30 percent of the planet by 2030 if we are to stand any chance of averting the worst consequences of runaway climate change and biodiversity loss.
