How To Protect The Ocean

The ocean is facing some of the biggest challenges in its history. Rising temperatures, marine heatwaves, coral bleaching, habitat loss, and overfishing continue to put pressure on marine ecosystems around the world. If you only follow the headlines, it can feel like ocean conservation is losing the battle. But hidden within a recent United Nations ocean report is a surprising reason for optimism. While ocean health continues to decline in many areas, the systems designed to protect the ocean are getting stronger. Countries are expanding marine protected areas, improving international...

How To Protect The Ocean

For decades, Indigenous communities were often asked whether they approved of projects happening in their territories. But a different question is now emerging: why should they not own part of those projects? In this episode of How to Protect the Ocean, Andrew Lewin looks at the shift from consultation to Indigenous ownership in ocean conservation, fisheries, infrastructure, and ocean technology. From the Mi’kmaq ownership stake in Clearwater Seafoods to the future of ocean data, monitoring, and blue economy projects, this episode asks who gets to lead, who benefits, and why ownership...

Pilot whales rely on sound for nearly every aspect of their lives. They use vocalizations to communicate with family members, coordinate movements, find food, and navigate through their environment. But what happens when the ocean becomes so noisy that those sounds are drowned out? In this episode of How to Protect the Ocean, we explore new research suggesting that commercial shipping noise in the Strait of Gibraltar may be interfering with the ability of pilot whales to hear and communicate with one another. The Strait of Gibraltar is one of the busiest shipping routes on the planet,...

In this episode of How to Protect the Ocean, Andrew Lewin looks at the Trump administration’s move to reopen protected marine sanctuary waters to commercial fishing and asks a bigger question: who actually benefits when public ocean resources are opened up? The episode breaks down why marine protected areas matter, how fisheries recover when protections stay in place, and why local and Indigenous fishing communities may not be the ones who gain when large commercial fleets get access.

A viral underwater video of a great white shark in the Mediterranean Sea recently captured the attention of people around the world. For many viewers, the footage seemed to show a shark appearing in a place where it shouldn’t be. But the truth is much more interesting. Great white sharks have been documented in the Mediterranean for decades, yet they remain one of the most mysterious and least understood apex predators in the region. In this episode of How to Protect the Ocean, Andrew breaks down why this sighting matters and what the public often gets wrong about stories like this. The...

Ocean conservation is often treated like an impossible problem, but the truth is simpler: when strong laws are created, enforced, and guided by science, ocean protection works. In this episode of How to Protect the Ocean, Andrew Lewin looks at the unglamorous but powerful role of legislation in ocean conservation. From Canada’s Oceans Act and marine protected areas to the U.S. Endangered Species Act, Marine Mammal Protection Act, and Magnuson-Stevens Act, this episode shows how laws can help recover species, rebuild fisheries, and protect habitats. But laws only work when governments follow...

Canada has a rare chance to become a global ocean conservation leader, but the path is not simple. In this episode of How to Protect the Ocean, Andrew Lewin breaks down Canada’s proposed $3.8 billion nature strategy, what it could mean for marine protected areas, and why ocean protection matters as development pressures grow. From pipelines and shipping to offshore oil and gas, fisheries conflicts, climate change, and Arctic access, Canada’s ocean future is being shaped right now. This episode looks at the promise, the risks, and the question every coastal nation should be asking: what...

Are We Protecting the Ocean Fast Enough? show art Are We Protecting the Ocean Fast Enough?

How To Protect The Ocean

The world has now protected about 10% of the ocean, a major milestone compared to where we were a decade ago. But with the global 30x30 target aiming to protect 30% of land and ocean by 2030, the big question is whether we are protecting the right places, fast enough, and with enough enforcement to make those protections real. In this episode, Andrew breaks down why 10% ocean protection is worth celebrating, why the next 20% will be difficult, and why small coastal protected areas still matter even if they do not add much to the global percentage.

Many people feel powerless when it comes to environmental issues. Whether it's climate change, habitat destruction, or controversial development projects, it can seem like the biggest decisions are made without public input. But recent protests against proposed AI data centers are reminding us that communities still have influence when people choose to get involved. Across North America, residents have been raising concerns about water use, energy demand, environmental impacts, and transparency surrounding AI data center developments. By attending meetings, contacting elected officials, and...

How To Protect The Ocean

Ocean conservation often focuses on threats: climate change, overfishing, plastic pollution, deep-sea mining, and political failure. But on World Ocean Day, this episode takes a step back to ask a deeper question: why do we protect the ocean in the first place? I reflect on the emotional, cultural, and personal connections people have with the ocean, from living near the coast to watching whales, exploring tide pools, diving, kayaking, listening to waves, or simply standing beside water and feeling calmer. The episode argues that ocean protection cannot only be about resources, regulations, or...

Global tuna fisheries are facing mounting pressure from overfishing, bycatch, and unsustainable fishing practices. Gala Moreno from the International Sustainable Seafood Foundation (ISSF) shares her expert insights on the current state of tuna populations and the urgent need for sustainable solutions. She explains how ISSF is collaborating with fishers, policymakers, and scientists to create strategies that protect tuna stocks while supporting the fishing industry. From improving fishing gear to implementing science-based management, Gala provides a clear picture of what it takes to maintain a healthy balance between conservation and commercial interests.

One of the most fascinating parts of the conversation is Gala’s insight into Fish Aggregating Devices (FADs). She breaks down how these devices work to attract fish, the environmental risks they pose, and the innovative strategies being developed to minimize their impact — including non-entangling and biodegradable FADs. Gala also discusses the exciting advancements in acoustic technology that are helping fishers identify tuna species more accurately, reducing bycatch and improving fishing efficiency.

This episode offers a powerful look at the intersection of science, policy, and industry in protecting one of the ocean’s most valuable resources. Gala’s expertise highlights the importance of collaboration and data-driven decision-making in shaping the future of sustainable tuna fisheries. Whether you’re passionate about marine conservation or simply curious about where your seafood comes from, this conversation is packed with valuable insights.
