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_outlineKey Considerations for Restoring Mangroves
Site Selection:
It is crucial to choose appropriate locations for planting mangroves. Areas that are prone to tidal flooding may not be suitable, as seedlings can drown. Historical mangrove sites may no longer be viable due to changes in land and sea levels.
Long-Term Planning:
Restoration efforts should focus on the longevity of the mangrove ecosystem. This includes monitoring the planted areas over time to ensure that seedlings survive and grow into established mangrove forests.
Biodiversity:
Avoid monoculture planting (e.g., only red mangroves) as it can lead to vulnerabilities. Diverse mangrove species should be planted to enhance resilience against pests and environmental changes.
Public and Private Partnerships:
Collaboration between companies and government entities can be beneficial, but it is essential to ensure that local communities retain ownership rights to their land and that restoration efforts do not lead to land grabbing.
Carbon Sequestration:
While mangroves are effective carbon sinks, the focus should not solely be on carbon credits. Restoration projects must ensure that they are genuinely contributing to biodiversity and ecosystem stability.
Monitoring and Reporting:
Companies involved in restoration should commit to long-term monitoring of their projects to demonstrate success and avoid greenwashing. This includes regular updates on the health and growth of the mangrove areas.
Adaptation to Climate Change:
Restoration strategies must consider the impacts of climate change, such as rising sea levels and increased storm surges, which can affect the viability of mangrove habitats.
By addressing these considerations, restoration projects can be more effective and sustainable, ultimately leading to healthier coastal ecosystems.
