Episode 15: Ocean Census: Species discovery at speed and scale

 
Charles Darwin once dismissed the ocean as a ‘tedious waste, a desert of water.’ Some of his contemporaries disagreed. The brave Challenger expedition of the 1870s set out to discover what lurked beneath, traversing over 100,000 kilometres and discovered 4,772 specimens, from sea snails to snake eels, discovered the deepest trench on earth, and toppled false assumptions about the lack of life under the waves. Over a century later, the Census of Marine Life picked up the baton. An eighty-country collaboration, with 2,700 scientists, the project identified another 6,000 species. Yet even these numbers are a literal drop in the ocean.

Oliver Steeds, Ocean Census director and chief executive of Nekton, a UK-based marine science and conservation institute, speaks to Naka Kondo, the lead editor of Back to Blue initiative about a new mission, the Ocean Census, launches this year with a far greater ambition: to find at least 100,000 new marine species in its first decade.

Episode 14: Sarah Doll from Safer States, on the role of government in tackling forever chemicals in drinking water

 
On March 14th 2023 the US Environmental Protection Agency (EPA) announced a proposal to establish legally enforceable levels for six types of ‘forever chemicals’ known as per- and polyfluoroalkyl substances (PFAS). It is expected to prevent thousands of deaths and reduce tens of thousands of serious illnesses attributable to PFAS.

The rule would require public water systems to monitor PFAS levels, notify the public of these and reduce them if exceeding the proposed standards. Developed over several years and grounded in the authority that the EPA has from US Congress, through the Safe Drinking Water Act, the goal is to issue a final PFAS drinking water standard by the end of 2023 or early 2024. This will result in a standard to which all water systems in the US must adhere.

Episode 13: Takeaways from the World Ocean Summit 2023

 
The World Ocean Summit is an annual global event run by The Economist Group, which brings together the wide ocean community, from business and finance to governments, national and international policy-makers, civil society and academia. This year, we celebrated the 10th anniversary of this event in Lisbon, Portugal.

In this episode, Martin Koehring, head of the World Ocean Initiative at Economist Impact, shares his firsthand experience at the summit and his key takeaways, with Naka Kondo, lead editor of Back to Blue at Economist Impact.

Episode 12: Peak plastics: bending the consumption curve

 
The world will continue to drown in plastic waste unless a bold and comprehensive set of policy changes is applied – this is according to Peak plastics: bending the consumption curve – a new report by Back to Blue, an initiative of Economist Impact and the Nippon Foundation. We delve into how we can decisively tackle plastic waste that is polluting our ocean and land environments with guest, Winnie Lau, project director of the Preventing Ocean Plastics project at The Pew Charitable Trusts. What will it take to decisively tackle the plastic waste crisis? Can we bend the consumption curve?

Episode 11: Ocean Acidification: A crisis in the making

 
The UN’s Sustainable Development Goal 14, Target 14.3, calls for minimising and addressing the impacts of ocean acidification through co-operation at all levels. There is an urgent need for scientific communities to come together with the media, education systems, policymakers and civil society to help bring more attention to the issue and to come up with technological solutions and robust legislation.

Listen to the panel discussion on ocean acidification by Steve Widdicombe, director of science, Plymouth Marine Laboratory, Peter Thomson, United Nation Secretary-general’s special envoy for the ocean, Malaika Vaz, Explorer, National Geographic, and Founder, Untamed Planet and moderated by Charles Goddard, editorial director, Economist Impact.

The Back to Blue team was at the UN Ocean Conference in Portugal and spoke to President Surangel Whipps Jr. of Palau about the ocean pollution issues they face, and Professor Bethanie Carney Almroth, Associate Professor of EcoToxicology, University of Gothenberg about her research into marine pollution and why she and her colleagues believe the pollution planetary boundary has been breached in the ocean.

Episode 7: The Invisible Wave: Can green and sustainable chemistry be the solution?

 
What is green and sustainable chemistry and can it be the solution to marine chemical pollution? What role can the private sector play?
