Half of Murres seabird population dies after this happened
How To Protect The Ocean
In this episode of the How to Protect the Ocean podcast, host Andrew Luan discusses the significant decline in the population of common murres, a seabird species in Alaska, which has seen about half of its population die off—approximately 4 million individuals—since the marine heat wave known as "the blob" occurred from 2014 to 2016. The primary reason for this drastic decline is linked to the effects of the heat wave on the marine food web rather than direct thermal stress on the birds themselves. The heat wave caused shifts in the availability of food sources, leading to starvation among...

Plastic Pollution Clean Up Through Absorption
How To Protect The Ocean
Plastic pollution clean up through absorption is now a possibility by using a combination of cotton and chittin to take microplastics out of the ocean...but can this work at scale? In this episode of the "How to Protect the Ocean" podcast, host Andrew Lo discusses the pressing issue of microplastics in the ocean and introduces a promising new method for their absorption using a combination of cotton and chitin. The mechanism involves creating a sponge-like substance called CT cell biomass, which combines cellulose from cotton and chitin from squid. This innovative material is designed to...

Climate Action When Governments Won't Help
How To Protect The Ocean
In this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin discusses the pressing issue of climate change and the challenges posed by government inaction. With the recent political shifts in North America, particularly the incoming administration in the United States, there are concerns about the rollback of environmental regulations and policies that protect the ocean and climate. Key points include: Government Inaction: The episode highlights the potential consequences of a new U.S. administration that may prioritize economic interests over environmental protection,...

Orcas Playing with Their Food: Wearing Salmon on Their Head
How To Protect The Ocean
Orcas playing with their food is not a new behavior; however, wearing salmon on their heads is not usual. In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses a fascinating phenomenon involving orcas wearing salmon as hats. A recent photograph captured an orca in Puget Sound sporting a salmon on its head, reminiscent of similar behaviors observed in the 1980s when orcas from the southern resident population also donned salmon hats. Lewin explores the potential reasons behind this behavior, suggesting it could be a playful act, a celebration of a successful...

Leave the seashells on the Seashore
How To Protect The Ocean
Seashells on the seashore are being taken in large quantities and it's increasing erosion along beaches. A new study reveals the tourism industry is taking too many seashells along coastlines in Costa Rica. In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses the environmental impact of taking seashells from coastal areas, particularly in Costa Rica. He highlights a growing crisis where the removal of seashells, driven by tourism, destabilizes beaches, accelerates erosion, and harms marine ecosystems. Seashells are essential for various marine species,...

Abandoned Fish Farms in Greece: Ghost Farm Clean Up by Healthy Seas
How To Protect The Ocean
Abandoned fish farms in Greece are plaguing the coastline with marine debris; however, Healthy Seas is working to clean up some of the sites and raise awareness for support to tell the Greek government that fish farm owners should be responsible for cleaning up their sites once the business is done operating. In this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin discusses the pressing issue of ghost farms—abandoned fish farms that are polluting oceans, particularly in Greece. The episode highlights the work of the organization Healthy Seas, which is actively...

Solar Panel Efficiency Improvements Mimicking Giant Clam Algae
How To Protect The Ocean
In this episode of the "How to Protect the Ocean" podcast, host Andrew Luan discusses the fascinating connection between giant clams and the efficiency of solar panels. He highlights the vibrant colors of giant clams, which are not only visually stunning but also play a crucial role in coral reef ecosystems, particularly in the Southeast Pacific. The key focus is on the algae, specifically zooxanthellae, that live within the soft tissue of giant clams. These algae absorb sunlight and are essential for the clams' survival, as they facilitate photosynthesis and contribute to the clam's calcium...

Orcas vs. Whale Sharks: A New Apex Predator Dynamic
How To Protect The Ocean
In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses the fascinating behavior of orcas, particularly their recent predation on whale sharks, the largest fish in the ocean. Orcas, known as apex predators, have been observed hunting whale sharks in the Gulf of California. This behavior was documented in a new study published in the journal Frontiers of Marine Science, which includes video footage and images of the attacks. The orcas target the whale sharks by striking their underbelly and grabbing their pectoral fins, aiming for the nutrient-rich liver,...
info_outlineIn this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin discusses the pressing issue of plastic pollution and highlights a promising biological solution involving African mealworms.
The episode focuses on the Kenyan lesser mealworm, a larval form of the Alphitobius darkling beetle, which has shown the ability to break down polystyrene, commonly known as styrofoam. This capability is attributed to the unique microbes and bacteria in the mealworms' gut. Researchers are studying these gut bacteria to identify specific communities that facilitate the degradation of plastic materials.
Key findings from the research indicate that the mealworms can effectively digest polystyrene when provided with a nutrient-rich diet, such as bran, alongside the styrofoam. This balanced diet appears to enhance the production of the necessary bacteria and enzymes to break down plastic. The study revealed significant shifts in bacterial composition based on the mealworms' diet, suggesting that the gut microbiome adapts to optimize plastic degradation.
The episode emphasizes the potential of harnessing these naturally occurring bacteria and enzymes for large-scale applications in plastic waste management, particularly in regions like Africa, where plastic waste poses significant environmental challenges. By isolating and utilizing these microbial communities, there is hope for developing innovative methods to biologically process plastic waste, reducing reliance on harmful chemical recycling methods.
The podcast presents a hopeful perspective on using biological solutions, like the African mealworm, to combat plastic pollution and promote environmental conservation.
