How To Protect The Ocean

Have you ever had an idea for your community, like a beach cleanup, a water fountain, or a patch of shoreline that needs some love, and thought, "If I just had a little money, I could make this happen"? That kind of funding is hard to find. In the UK, there's a charity built for exactly that. Sea-Changers was founded about 15 years ago by Helen Webb and Rachel Lopata, two divers with no background in marine science who watched the places they loved underwater start to decline. Instead of starting one project, they started a way to fund hundreds. They bring in money from businesses and...

How To Protect The Ocean

"We'll never see that in our lifetime." You've probably heard it about the ocean. Andrew has heard it plenty, and admits he's said it too. For years it was the standard answer about protecting the high seas, the two-thirds of the ocean that lies beyond any country's borders. Then the High Seas Treaty was agreed, entered into force in January 2026, and passed 100 countries in September, Canada included. In this week's wrap-up, Andrew uses that win to show why a global plastics treaty can happen too, and how it gets built from the ground up. He walks through the ladder: a town like Tofino...

"You can't care about plastic. Your phone is made of plastic." If you've ever heard that, you know what it's for. It's designed to make you feel like a hypocrite, so you give up. In this episode, Andrew goes back to one of the most famous moments in plastic pollution: the 2015 video of researchers in Costa Rica pulling a plastic straw from an olive ridley sea turtle's nose. A few months later, the same researcher pulled a plastic fork from another turtle. The straw video helped spark a global push against single-use plastics, and then the straw itself became a punchline. Andrew explains why...

Picture a beach cleanup. Two hours of hauling bottles, wrappers and foam off the sand. Now picture the same beach ten years later, where you walk the whole length and come home empty-handed. Not because nobody cleaned it, but because there's nothing left to clean. That's a real story, and it happened in Tofino, a surf town on the west coast of Vancouver Island. In 2016 its beaches were covered in plastic, and the local Surfrider chapter realized they could clean every weekend for the rest of their lives and it would never stop. So they changed tactics. They went to the businesses handing out...

How To Protect The Ocean

Do you ever feel disconnected from ocean action? You sign the petition, you donate, you share the post, and you still don't feel like you're doing the work. Andrew knows the feeling. Fresh out of his undergrad, he emailed organization after organization offering to help for free, and mostly heard nothing back. In this episode he explains why that happens (it usually comes down to trust and how organizations take on volunteers), and how to get past it. He also retells the story of Lilly Woodbury from yesterday's episode: an environmental studies grad who kept hitting the same wall until she...

How To Protect The Ocean

Do you ever feel like ocean action is happening somewhere else? You sign the petition, maybe donate, but you're not really part of the work. Lilly Woodbury knows that feeling, and she found her way in by walking into a Surfrider meeting in Tofino in 2016. Lilly is the campaigns and storytelling director at Surfrider Foundation Canada. In this episode she tells Andrew how a small volunteer chapter helped Tofino and Ucluelet ban plastic straws, bags, cutlery and foam containers, and how Tofino became the first municipality in Canada to ban single-use plastic water bottles. Ten years in, she says...

How To Protect The Ocean

Picture a kid at an aquarium in Durban, standing in front of the penguins with a pen and a postcard. She writes one sentence, a promise to change one habit for the ocean, and drops it into a little post box. More than a year later, researchers emailed visitors like her to ask if they'd kept their promise. About half could point to a real change they'd made. This week's episodes covered a lot: marine protected areas nobody can name, a reef that rebuilt itself, and why "fishing is bad" pushes people away. If all of that left you feeling heavy, this episode is for you. Andrew talks about...

Picture a woman on a beach before sunrise, sorting the night's catch to feed her kids. Now picture a campaign poster that says "Stop eating fish." That poster just reached her. When conservation messages treat every fisher the same, the people with the smallest footprint stop coming to meetings, stop sharing catch data with scientists, and step out of the conversation entirely. Andrew walks through the Illuminating Hidden Harvests study from the FAO, Duke University and WorldFish, which found that small-scale fisheries land at least 40% of the world's wild catch and employ about 60 million...

In 2023, a marine heat wave settled over Palmyra Atoll, a remote ring of coral islands about 1,000 miles south of Hawaii, and stayed for more than half a year. Some of the reef’s most vibrant corals turned white. Joe Pollock of The Nature Conservancy, who monitors the reef, admitted he didn’t know if it would come back. Three years later, he put his face in the water and found the reef floor covered in baby corals. In this episode, I break down why Palmyra recovered when so many reefs struggle. It comes down to an intact food web: parrotfish that graze algae off the reef, a bubblegum-pink...

How To Protect The Ocean

Quick test: name one marine protected area in your country. If you came up blank, you're in good company. When an aquarium in Durban, South Africa surveyed its visitors, fewer than one in five could name a single MPA. Andrew Lewin explains why that silence is one of the biggest threats MPAs face, because a place nobody can name is a place nobody defends when it gets weakened, shrunk or quietly reopened. This episode follows South Africa's long road from protecting 0.4% of its mainland ocean to 5.4%, and the communicators who realized the science and consultations were done but the public was...

In 2023, a marine heat wave settled over Palmyra Atoll, a remote ring of coral islands about 1,000 miles south of Hawaii, and stayed for more than half a year. Some of the reef’s most vibrant corals turned white. Joe Pollock of The Nature Conservancy, who monitors the reef, admitted he didn’t know if it would come back. Three years later, he put his face in the water and found the reef floor covered in baby corals.

In this episode, I break down why Palmyra recovered when so many reefs struggle. It comes down to an intact food web: parrotfish that graze algae off the reef, a bubblegum-pink crustose coralline algae that holds space for young corals, and sharks that keep the whole system in balance. Then we travel to Tsitsikamma, Africa’s oldest marine protected area, where Rhodes University researchers found that protected red roman stayed active through an extreme cold spell while fished populations slowed down.

Protected areas buy reefs time, and cutting emissions decides how much time they need. I close with one simple action you can take this year: submitting a short comment of support the next time a marine protected area consultation opens in your region. Here’s the template from the episode, ready to copy and paste: “I support protecting this area because intact ecosystems recover faster from heat waves. Please give science-based protections full weight.”

Takeaways

  • Bleached coral is starving, not dead, and can recover if the heat breaks in time
  • Palmyra’s reef recovered with a “sea of baby corals” whose parents survived the 2023 bleaching
  • Corals that survive bleaching often tolerate heat better and can pass that tolerance to offspring
  • Parrotfish, crustose coralline algae, and sharks form the “crew of three” that keeps a reef ready to recover
  • Protected red roman in South Africa kept moving through a cold spell that slowed fished populations
  • At 1.5°C of warming, 70 to 90% of coral reefs are projected to decline, so emissions cuts remain the primary fix
  • One two-sentence comment on an MPA consultation counts
