How To Protect The Ocean

Nature is protected by laws on paper, but what happens when those laws are not enforced? On the high seas, beyond national borders, illegal fishing, whaling, and environmental exploitation often operate in legal gray zones. Environmental lawyer and author Sarah Levy joins the show to unpack how international ocean law actually works, where it fails, and why enforcement remains the biggest challenge in marine conservation. Law and activism collide in this deep dive into Sea Shepherd, Captain Paul Watson, and the controversial role of aggressive nonviolence in protecting marine wildlife. We...

How To Protect The Ocean

Nature is absorbing more heat than we realize, and most of it is going into the ocean. Global ocean heat content has reached record highs, confirming what climate scientists have warned for years: the ocean has absorbed more than 90 percent of the excess heat trapped by greenhouse gases. Data from NOAA and findings summarized in the IPCC AR6 report show a continued upward trajectory, with no sign of stabilization. Ocean heat is not just a statistic. It is driving stronger marine heatwaves, coral bleaching, shifting fisheries, oxygen loss, and rising sea levels through thermal expansion. Peer...

How To Protect The Ocean

Seagrass meadows may be the most powerful climate solution underwater, and almost no one is talking about them. Research published in Nature Climate Change shows that seagrass ecosystems store vast amounts of carbon in their sediments, sometimes for centuries. Unlike forests, much of this carbon is locked below ground in oxygen poor environments, reducing the risk of rapid release. But when seagrass meadows are degraded, that long-stored carbon can return to the atmosphere. A study in Science Advances demonstrates that large scale seagrass restoration can significantly enhance blue carbon...

How To Protect The Ocean

Ocean fish populations are under pressure, and public money is still part of the problem. The World Trade Organization adopted a Fisheries Subsidies Agreement to curb harmful funding tied to illegal fishing, but major loopholes remain. Billions of dollars in government support continue to prop up industrial fleets that contribute to overcapacity and overfishing. Research published in Nature estimates that governments provide approximately 35 billion USD annually in fisheries subsidies, with the majority considered harmful or capacity enhancing. While the WTO agreement marks progress, it does...

How To Protect The Ocean

Atlantic fish stocks sit at the center of a new political push to expand commercial fishing in federal waters. A recent U.S. executive action signals increased access for industrial fleets, raising critical questions about how economic policy aligns with science based fisheries management. The United States promotes its fisheries system as one of the most sustainably managed in the world, built on stock assessments, annual catch limits, and rebuilding plans overseen by NOAA Fisheries. Yet globally, more than one-third of assessed fish stocks are already overfished, according to the FAO. When...

info_outline Are All Plastics Toxic? What the Science Actually Says About Microplastics and Human Health show art Are All Plastics Toxic? What the Science Actually Says About Microplastics and Human Health

How To Protect The Ocean

Microplastics are now found in the deepest ocean trenches, Arctic ice, seafood, drinking water, and even human blood. Headlines often claim that all plastics are toxic, but what does the science actually say? Recent research has detected microplastics in human lungs, placentas, and cardiovascular tissue, raising urgent questions about inflammation, chemical exposure, and long term health risks. At the same time, scientists caution that not all plastics behave the same way, and toxicity depends on polymer type, additives, breakdown processes, and exposure levels. This episode breaks down the...

How To Protect The Ocean

Marine Protected Areas are expanding faster than ever, but new research raises an uncomfortable question: are they actually protecting top predators? Satellite tracking of silky sharks shows that even inside designated protected zones, highly migratory species frequently move into heavily fished waters. If sharks cross invisible boundaries every day, how effective are those boundaries in the first place? Shark conservation and ocean governance collide when industrial fishing fleets concentrate along MPA borders and enforcement resources struggle to keep up. Studies reveal that some protected...

info_outline Paper Parks? Why Marine Protected Areas Are Failing Sharks show art Paper Parks? Why Marine Protected Areas Are Failing Sharks

How To Protect The Ocean

Marine Protected Areas are expanding worldwide, but new research shows that protection on paper does not always translate to protection in reality. Satellite tracking of silky sharks reveals that highly mobile predators regularly cross MPA boundaries into heavily fished waters, exposing serious enforcement gaps. When fishing fleets concentrate along invisible ocean borders, even large reserves struggle to deliver real conservation outcomes. Shark conservation and ocean governance are at the center of this story. Studies published in peer-reviewed journals and vessel tracking data from Global...

How To Protect The Ocean

Coral Reef Recovery is happening faster than many scientists once believed possible, but only under the right conditions. Long-term monitoring from the Caribbean and Indo Pacific shows that reefs can regain coral cover and rebuild three-dimensional structure when fishing pressure is reduced, water quality improves, and protections are enforced. The idea that reefs are doomed after bleaching events is being challenged by real data collected over decades. Reef Resilience Science reveals that recovery is not random. Areas with healthy herbivore populations, strong marine protected area...

How To Protect The Ocean

Coral reefs can still show living coral cover and yet be ecologically collapsing beneath the surface. In this episode, we break down new coast-to-coast reef assessments from Thailand that reveal a critical warning sign: reefs are losing structural complexity even when coral is still present. Structural complexity, also known as rugosity, is what gives reefs their three-dimensional shape. That shape creates habitat for fish, supports predator-prey balance, fuels biodiversity, and protects coastlines from storms. New research published in Science and Nature Climate Change shows that repeated...

The largest solar farm on the ocean is now running off the coast of China as the country continues to invest in ways to support its sustainable energy needs. 

In the "How to Protect the Ocean" podcast, host Andrew Lewin discusses China's deployment of the world's largest open sea offshore solar panel farm. The project, developed by CHN Energy, spans 1,223 hectares (3,023 acres) and is located 8 kilometers off the coast of China. It aims to generate one gigawatt of renewable energy and is notable for its innovative use of offshore solar technology.

Pros of the Offshore Solar Project

  1. Efficient Land Use: Utilizing water bodies for solar energy reduces the need for land clearing and habitat destruction typically associated with land-based solar farms.

  2. Reduced Evaporation: The solar panels cover the water surface, which can help conserve water by reducing evaporation rates in reservoirs and agricultural areas.

  3. Improved Solar Efficiency: The cooling effect of water can enhance the efficiency of solar panels compared to those installed on land.

  4. Dual Use Potential: Floating solar farms can coexist with hydroelectric facilities, optimizing energy production and utilizing existing infrastructure.

  5. Algal Bloom Reduction: The solar panels can help suppress harmful algal blooms in aquatic systems by limiting sunlight penetration.

  6. Clean Energy Generation: The project contributes to renewable energy production, reducing greenhouse gas emissions and reliance on fossil fuels.

Cons of the Offshore Solar Project

  1. Impact on Aquatic Systems: The shade from solar panels may alter water temperature and light penetration, potentially disrupting habitats for aquatic plants and animals.

  2. Habitat Disruption: The solar farm installation could affect fish spawning areas and migratory patterns, similar to concerns raised about wind farms.

  3. Material Degradation: Using plastics and metals in solar structures could lead to microplastic contamination and chemical pollution over time.

  4. Recreational Disruption: Floating solar farms may hinder recreational activities, fishing, and navigation in the area.

  5. Installation Risks: The anchoring and cabling required for the solar systems could disturb sediments and harm local aquatic habitats.

  6. Vulnerability to Weather Events: The structures may be susceptible to damage from storms, hurricanes, and flooding, potentially releasing debris or pollutants into the water.

The episode emphasizes the need for careful planning and mitigation strategies to address the potential environmental concerns associated with floating solar farms. While the project presents a promising opportunity for renewable energy generation, it also raises important questions about the ecological impacts on marine environments. The host encourages listeners to engage in the conversation about the balance between renewable energy development and ocean conservation.
