Orcas vs Great White Sharks: How Killer Whales Are Changing Shark Populations
How To Protect The Ocean
Orcas vs Great White Sharks is more than a dramatic headline—it’s a sign of how ocean ecosystems are shifting before our eyes. New drone footage shows orcas in the Gulf of California attacking and killing juvenile great white sharks in what scientists believe are nursery zones. The footage, captured in 2020 and 2022, reveals orcas flipping young sharks onto their backs, inducing tonic immobility, and surgically removing their livers—a precise and efficient hunting technique that may reshape predator-prey dynamics. For years, scientists have known about great white shark nurseries, but...

Seagrass Decline in Moreton Bay: What Long-Term Research Reveals About Ocean Change
How To Protect The Ocean
Seagrass meadows are among the most vital yet overlooked ecosystems on our planet. In this episode of How to Protect the Ocean, Andrew Lewin explores a new 19-year study from Moreton Bay, Australia, which shows that seagrass coverage and diversity are declining over time despite short-term recovery periods. This long-term research reveals that while short-term studies might show seagrass bouncing back after storms or floods, the bigger picture tells a story of gradual loss and ecological transformation. The episode also highlights why this decline matters: seagrass meadows are nurseries for...

Bill Gates & Climate Change: Why His Latest Comments Shocked the Climate Community
How To Protect The Ocean
Bill Gates and Climate Change have become a trending topic after the billionaire philanthropist argued that the world is too focused on cutting carbon emissions and not focused enough on improving human welfare. In this episode, I unpack what Gates said, why it caused such a reaction, and how his argument connects to decades of work in climate justice and climate equity. Many climate justice organizations have long emphasized that people struggling with hunger, illness, or poverty cannot prioritize environmental action until their basic needs are met. Gates’s claim—that people fighting to...

Are These Whales Doing Better?
How To Protect The Ocean
North Atlantic right whales have been teetering on the edge of extinction for decades, with fewer than 400 individuals left. But recent reports hint at a small sign of hope: the population may finally be stabilizing, or even slightly increasing. In this episode, Andrew Lewin explores what that really means. Conservation efforts, from slower ship speeds to ropeless fishing gear, are starting to make a difference—but are they enough to ensure these whales survive? Andrew breaks down the latest science, the hard numbers from NOAA’s newest technical memo, and why every calf, especially every...

info_outlineIn this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin interviews Dr. Annalisa Bracco, a professor at Georgia Tech specializing in ocean and climate dynamics. The discussion centers around innovative climate solutions, moving away from the typical focus on the negative impacts of climate change.
Key Climate Solutions Discussed:
Sargassum Management:
Problem: Since 2011, there have been significant blooms of sargassum in the tropical Atlantic, impacting beaches in the Caribbean and Gulf of Mexico. These blooms require costly cleanup efforts, amounting to approximately $300 million per year.
Solutions:
-
-
Sinking Sargassum: Research is being conducted to explore the feasibility of sinking sargassum to sequester carbon. This involves understanding the ecological impacts and ensuring that the carbon captured is not released back into the atmosphere.
-
Biofuel Production: Collaborations with engineers and biologists are underway to convert sargassum into biofuels. One approach involves using black fly larvae, which can efficiently consume sargassum and accumulate lipids for biofuel extraction.
-
Bricks from Sargassum: A small business in Mexico is creating bricks from dried sargassum, which are reported to be more resilient to storms than traditional building materials.
-
Coral Reef Connectivity:
-
-
Dr. Bracco's team is using machine learning to study the connectivity among coral reefs, which is crucial for understanding how larvae disperse and how healthy ecosystems can support one another.
-
The research highlights the dynamic nature of coral ecosystems, particularly in the Pacific, where certain areas can recover from bleaching events due to the exchange of larvae. In contrast, the Atlantic faces challenges due to pollution and overfishing, which hinder recovery.
-
Interdisciplinary Collaboration:
-
-
The episode emphasizes the importance of interdisciplinary work in addressing climate issues. Dr. Bracco collaborates with experts from various fields, including biology, engineering, and computer science, to develop comprehensive solutions to climate challenges.
-
Overall, the episode provides a hopeful perspective on climate solutions, showcasing innovative approaches to managing ocean health and addressing the impacts of climate change.
