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...

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...

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...

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...

Most people can't name a single marine protected area in their own country. Dr. Judy Mann-Lang found that out the hard way when she asked aquarium visitors to name one and they named the aquarium. With South Africa's new MPAs stalled on a minister's desk and oil and gas lobbyists in the room, she realized the ocean needed public support that didn't yet exist. That gap became MPA Day. Judy spent 30 years at uShaka Sea World in Durban, moving from education to CEO to conservation strategist, then five years with the Two Oceans Aquarium, earning a PhD on how effectively aquariums communicate...

You bought the fish with the green check mark. Investigators with The Outlaw Ocean Project then checked the supply chains behind hundreds of seafood companies making sustainability claims, and more than half had a documented crime or concern somewhere upstream. In the final episode of our fish feed series, Andrew Lewin looks at what sustainable seafood labels cover and where their audits stop. Follow fishmeal from Western Sahara to ASC-certified sea bass farms in Türkiye that supply UK supermarkets, and from the Golden Lead plant in Gunjur, The Gambia, to a certified shrimp feed mill in...

In a single day in March 2024, Gambian navy officers arrested eight industrial trawlers. Seven were fishing in waters reserved for local canoes, four were using illegal nets, and every one had switched off its tracking beacon. That one patrol shows a problem playing out across the global ocean. About three in four industrial fishing vessels are not publicly tracked, and many of the boats supplying the fishmeal that feeds farmed fish are among the hardest to see. In this episode of How to Protect the Ocean, Andrew Lewin follows the boats that catch the fish behind fish feed. He covers how...

On a May morning in 2017, the people of Gunjur in The Gambia woke to find their lagoon had turned red, with dead fish on the surface. Investigators traced the pollution to a fishmeal plant up the road. In this episode, Andrew Lewin follows the feed from West African beaches to farmed salmon fillets in Europe and North America, building on The Outlaw Ocean Project’s five-year investigation into the fishmeal industry. Small, oily fish like sardinella and bonga are everyday protein in Senegal and The Gambia. Fishmeal plants buy them in unlimited volumes, outbid the women who have smoked and...

Chitin, a substance found in the shells of seafood shellfish, has emerged as a promising alternative to traditional plastic. Researchers at the University of Connecticut have developed a method to extract chitin from crabs, lobsters, and other crustaceans. Historically, chitin extraction has been challenging due to the use of harmful substances like hydrochloric acid, which can harm the environment. However, the researchers have found a more sustainable approach using non-toxic and biocompatible byproducts from the biodiesel industry.
This breakthrough is significant because chitin-based products could offer a more environmentally friendly solution to plastic pollution. Chitin-based materials have the potential to break down more easily in the environment, reducing the harmful impact on ecosystems. With approximately six million tons of seafood waste generated in the US alone each year, there is a vast potential source of chitin that could be repurposed into sustainable products.
The innovative extraction process involves using organic acids like glycerol, choline chloride, lactic acid, or malic acid to separate chitin from the shellfish material. This method not only makes chitin extraction more efficient but also eliminates the use of corrosive substances that harm the environment. The resulting chitin can be used as a biodegradable replacement for petroleum-based plastics, offering a more sustainable option for various products.
Furthermore, the researchers are exploring additional applications for chitin, such as turning salvaged chitin into nutrient-rich fertilizer for crops. This demonstrates the versatility and potential value of chitin as a sustainable resource. The episode emphasizes the importance of investing in innovative research projects like this to drive positive change and reduce our reliance on fossil fuels.
Researchers have made a groundbreaking discovery in finding a more environmentally friendly way to extract chitin from shellfish, making it a viable option for plastic production. Traditionally, extracting chitin from shellfish has been a challenging and polluting process, involving the use of harmful substances like hydrochloric acid. However, a lab at the University of Connecticut has found a new method that utilizes non-toxic, biocompatible, and cost-effective byproducts of the biodiesel industry, such as choline chloride, glycerol, and organic acids.
This innovative approach involves creating a solvent rich in hydrogen bonds that can break down the original bond in the shellfish material, enabling the separation and release of chitin from other compounds in the shells' complex matrix. This method not only makes the extraction process more efficient but also eliminates the harmful environmental impacts associated with traditional extraction methods.
With this new extraction process, chitin can now be obtained sustainably from the shells of crabs, lobsters, crustaceans, and shrimp. This discovery opens up a world of possibilities for using chitin as a biodegradable replacement for petroleum-based plastics. The potential applications of chitin in plastic production are vast, offering a more sustainable alternative that breaks down harmlessly in the environment.
Furthermore, researchers are exploring additional uses for chitin, such as turning salvaged chitin into a nutrient-rich fertilizer for crops. This demonstrates the versatility and value of chitin as a resource that can be repurposed into valuable products, contributing to a more circular and sustainable economy.
Overall, this discovery represents a significant step towards reducing plastic pollution and transitioning towards more eco-friendly alternatives in plastic production. By investing in innovative research like this, we can pave the way for a more sustainable future and reduce our reliance on fossil fuels for plastic manufacturing.
Governments play a crucial role in driving innovation towards more sustainable practices and reducing reliance on fossil fuels. As discussed in the podcast episode, investing in innovative projects like the use of chitin to create sustainable products presents a significant opportunity for governments to lead the way in environmental conservation. Chitin, extracted from seafood waste, offers a biodegradable alternative to petroleum-based plastics, addressing the pressing issue of plastic pollution.
By investing in research and development of chitin-based products, governments can support the transition towards a more sustainable economy. This investment not only fosters technological advancements but also promotes job creation and economic growth in emerging industries focused on sustainability.
